While an "out of the box" install of Spring Roo provides a tremendous productivity improvement for new Java developers and seasoned architects alike, there are many exciting opportunities for further gains once you start developing Roo "add-ons". Writing a Roo "add-on" enables you to fine-tune how Roo works and add support for extra technologies. Despite such flexibility, add-ons are surprisingly easy to write and brief (many core Roo add-ons are only a dozen lines of code). This session will be of interest to anyone interested in developing their own Roo add-ons, as well as those who are simply curious how Roo works under the hood and want to gain a better understanding of the technology.

At its heart, Roo offers a core set of services that permit add-ons to be used. This session will explore everything you need to know to confidently develop your own add-ons. During this session Ben will actually build a simple Roo add-on live on stage. What better proof of how easy it is?! We'll do this by: Looking at how to check the Roo project out of SVN, build it, and configure your development environment to support add-on development. A quick tour of Roo's core infrastructure. This infrastructure includes major building blocks like the shell, file system manager, file system monitor, file undo capability, classpath abstraction, Abstract Syntax Tree (AST) parsing and binding, projec

Spring Security is a popular, open-source Java security framework that represents the Spring portfolio's official security capability. It has received hundreds of thousands of downloads, been ported to other platforms (such as Python and Microsoft .NET) and represents a popular choice in many banking, government, and military installations.

This session presents practical solutions for addressing today's complex enterprise application security requirements using Spring Security. It takes attendees on a step-by-step journey that begins with the simple security requirement of a login form, and grows to include more advanced requirements such as web request authorization, single sign on and federated identity, advanced method authorization, plus rich client security considerations. Many of the exciting new features in Spring Security 3 (such as Spring Framework 3-powered expression language authorization) will also be covered.

This session promises to be intensely demonstration-oriented, with at least five separate live demonstrations and code discussions. As such, you will not only discover the important architectural concepts and standards applicable to enterprise application security, but you'll also receive plenty of practical tips and solid advice on using this powerful and flexible security framework.

Building a desktop application is a hard task, there are some many things to keep track of that many projects simply fail to meet their goals. Setting up the project structure keeping each artifact on a well identified location given its responsibility and type, defining the base schema for managing the application's lif ecycle, making sure the build is properly setup, and more. These are recurring tasks that should be handled by a tool or better yet, a framework. Griffon is such a framework. Inspired by the Grails framework Griffon aims to bring the same productivity gains to desktop development, there are so many traits shared by both frameworks that a Grails developer should be able to pick up the pace fairly quick.

Come see how a restful desktop application can be be boostrapped in literally minutes thanks to the power of well thought conventions and a good deal of Groovy elbow grease. Welcome to the Griffon revolution.

By Andres Almiray

Testing a desktop application, an often neglected task left to the last possible moment if it is not entirely scrapped from the schedule, the QA team should be able to handle the load, ain't that right? with Griffon there are no more excuses, there is an easier way to make ends meet when testing a desktop application. Griffon will help you keep an eye on your application's green bar from the get go, it also comes with a full arsenal of plugins that make this task even more enjoyable and rewarding.

In this session we will sample each and every one of Griffon's testing plugins, like Easyb and FEST to name a few.

In the beginning Orbitz had a Jini based distributed system. The system design provided easy scalability and stability, but at the cost of tight coupling because of many shared modules and components, as well as Java serialization rules. In order to improve cohesion between individual services the decision has been made to migrate to a RESTful web services architecture. The new design is based on Google Protocol Buffers to define message formats and Spring/Spring MVC to handle client-server interaction. This resulted in a loosely coupled federation of services, each with its individual release and deployment schedule, which enabled more developer innovation and easier access to more data in a uniform fashion.

The audience will be shown in detail how to deal with Google Protocol Buffers, how to define and consume the messages, how to implement the client and the server sides using Spring and Spring MVC (showing custom Views, DataBinders and other Protobuf specific implementations of Spring/MVC components) and a demo building an actual client and a server in under 15 minutes. What you will get from this session: - using Google Protocol Buffers to constitute language neutral contracts - using standard HTTP plumbing and intermediaries - designing a reverse proxy for request routing based on RESTful URLs - establishing OLAs for governance and service isolation - utilizing the power of Spring/Spring M

How is your lone web server going to handle all the traffic you'll get when it lands on Slashdot or the front page of Digg? Probably not well. To prepare for all of this popularity you're going to need multiple servers, but there's more to it than buying hardware.

In this talk we'll look at implementing Tomcat's HTTP Session clustering, distributed second-level Hibernate caching using EhCache, and using the JDBC store feature of Quartz so your servers can handle the load while maintaining consistent data.

The Yahoo Performance Team has made a ton of great UI performance tuning information available, both online and in two books, "High Performance Web Sites" and the recently released followup "Even Faster Web Sites".

The Grails UI-Performance plugin implements many of these best practices, including compressing and minifying static and dynamic content, aggressive caching, bundling files, creating image sprites and more. We'll look at the wrong way to send content to your users' browsers and the right way, and use YSlow to measure the improvements along the way. Your users will appreciate the zippier response times, and you'll appreciate the decreased server load.

Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.

Dynamic languages provide a lot of power and flexibility compared to statically typed languages. Groovy brings that power and flexibility to the Java platform in a way that is totally compatible with all of your existing Java code, tools and infrastructure. This session covers all of the fundamentals of Groovy and gives developers a whole lot of practical information they need to get started with the language.

By Jeff Brown

There are many features provided by The Grails Framework which at first appear to be black magic. Where does the 'log' property come from? How do GORM dynamic finders really work? How can I add similar properties and behavior to classes at runtime? All of these questions will be answered during this session.

This session is for Grails developers who want to accelerate their Grails Kung-Fu to the next level and really take advantage of the power and flexibility that Grails has to offer.

For many, learning Groovy made you think differently about Java. Now it's time to think differently about Groovy. Although Groovy is not a functional language by many measures, it does support many of the common functional idioms and patterns. Come explore both how far functional programming can be pushed in Groovy, where functional programming can't currently go, and where functional programming is headed in future releases of both the language and the JVM.

Learn about morphisms, option types, tail call optimization, pattern matching, and functional composition in the context of solving classic CS problems side-by-side with a more traditional functional language, and decide for yourself how terms like elegance and simplicity should drive your coding. This is not meant to be an intro to functional programming but no prior experience is required.

"Tests don't break things; they dispel the illusion that it works." (Anonymous)

In this era of "Test-First" and "Test-Driven" development, the modern software engineer knows that testing is no longer an optional part of the process. You need to have the best tools at your fingertips: a set of utilities that maximize your results with a minimum of effort. Groovy offers Java developers an optimal set of testing tools.

In this talk, we use EasyB to gather user stories as executable documentation. We look at GroovyTestCases -- a drop-in replacement for JUnit TestCases that expand the pool of helpful assertions. We'll explore mocking and stubbing with Groovy. And we'll finally go public with Groovy's privacy "issues".

The Rails tenets are great, for web based applications. But how do the values hold up when applied to Desktop and Rich Internet Applications?

In 2004 the web development world was reshaped by a little framework named Rails. What is most notable about Rails was not the technical details of the framework, but the core values that drove these technical decisions. These values have evolved over the years and are now known as the Rails Tenets. How do these values hold when taken to the desktop and Rich Internet applications? It turns out most of these tenets work very well in a rich application setting, and only two (Fat Model/Skinny Controller and Use REST Interfaces) need alteration (Pervasive MVC and Use Data Binding respectively). This presentation will go over all the values and show how the Griffon framework applies them.

The Manifesto for Agile Software Development essentially focuses on meeting customer needs through reducing wasteful activities. For example, Agile developmental practices push for reducing repetitive documentation and for a rapid acceptance of change; yet, achieving these goals is by no means easy. While a process can enable increased collaboration, for instance, there are various tools that can effectively implement Agile principles. Once such tool is easyb (www.easyb.org), which is a Groovy based domain specific language, which facilitates collaboration by bridging those that define requirements (i.e. customers) and those who turn requirements into code (i.e. development). With easyb, collaborative teams can develop stories in a specific format which are then implemented as tests through a framework which marries the underlying application. This test suite enables change and produces accordance among Agile teams in short order.

In this talk, you will learn how to embrace collaboration and change rapidly by defining easyb stories that exercise a Java application end to end. You will learn how to define specific easyb structures, how to plug them into real code, and how to run them in an automated fashion. You will see first hand how non-coders can define tests easily and how the collaboration this brings yields working software faster.

Representational state transfer (REST) is a way of thinking, not a protocol or standard-- it's a style of designing loosely coupled applications that rely on named resources (in the form of URLs, URIs and URNs, for instance) rather than messages. Ingeniously, REST piggybacks on the already validated and successful infrastructure of the Web-- HTTP. That is, REST leverages aspects of the HTTP protocol such as GET and POST requests, which map quite nicely to standard business-application needs such as create read, update, and delete (CRUD). By associating requests, which act like verbs, with resources, which act like nouns, you end up with a logical expression of behavior: GET this document and DELETE that record, for example.

To quote Leonardo da Vinci, "simplicity is the ultimate sophistication." REST embodies this thought and thus yields highly scalable, loosely coupled systems that, as it turns out, are simple to build. There are a few mechanisms for implementing RESTful applications-- Restlets and JSR 311 are two in a handful of options; however, they address one aspect of RESTful applications and ignore other aspects like an ORM and testing. Groovy's Grails gives you the ability to apply RESTful techniques with a full fledged web application framework that supports an ORM and testing to boot! As you see, using Groovy's Grails framework makes building RESTful Web services a snap.

Traditional JSF development has gained a reputation for being overly complex and cumbersome. Spring Faces introduces a host of features that improve the development experience and performance a JSF application. In this session, attendees will see a real-time demonstration of how Spring Faces makes the JSF experience more productive and reduces the pain of container re-starts and verbose configuration.

This live coding session will highlight the features of Spring Faces that make using JSF and Spring together a more cohesive experience:

* High-level DSL for structuring control logic that utilizes EL and Groovy and is both easy to unit test and fully dynamic and refreshable in-container at runtime.
* Introduction of view and flow scopes that fit more naturally with JSF's stateful model
* Reduction in external configuration with no need for JSF managed- bean or navigation-rule definitions
* Easy-to-introduce client-side validation and Ajax
* Flow-managed persistence contexts that enable true transparent persistence.
* Simplified integration with Spring Security
* Less conceptual disconnect by enabling the Spring programming model throughout the stack ("turtles all the way down")

One of the more exiciting features in the new Servlet 3.0 specification is the standard support for asynchronous request processing, opening up a new gateway for innovative technologies. Asynchronous request processing breaks the thread per request limitation that the Servlet technologies have long suffered from. While containers have provided this functionality in the past, all implementations have been propriatery and often not offered complete solutions. The Servlet 3.0 asynchronous API aims to address a majority of the uses cases for true Web 2.0 functionality as well as keeping the complexity of asynchronous programming at a minimal level.

Groovy provides excellent facilities for parsing and creating XML. As well as providing syntactic sugar on top of traditional Java-based parsing approaches (e.g. SAX, DOM, StAX), it has its own XmlParser and XmlSlurper libraries which support XPath-like expressions at the object level (akin to LINQ in the .Net world). In addition, Groovy's markup builders provide an elegant and efficient way to create and modify XML. Groovy also has various options available for SOAP and RESTful web services. We'll examine the most popular of these.

We'll cover: * Reading, creating and updating XML using various approaches including the pros and cons of the various parsers and markup builders * dealing with XML namespaces and XPath * using other XML frameworks: XOM, Dom4j, JDom * integrating with XSLT, XQuery and validators * treating non-XML like XML * GroovySOAP, GroovyWS and Spring web services * JAXB, XmlBeans, CXF and Axis2 for SOAP web services * XML-RPC and RESTful options, RSS, ATOM * trade-offs using Apache Xerces or with native XML support on 1.4 through to 1.7 JVMs * Testing Web services with SoapUI * A quick look at Groovy integration in common XML/web-service tools * Groovy use in web service related products including ESBs

You've used Groovy to quickly hack together some short scripts or a simple Grails app. Now you want to treat it more seriously and apply best practices and tools. For Java you'd look at style and coverage checkers, JavaDoc, dependency injection, mocking, testing and build frameworks. For Groovy you have EasyB, Cobertura, CodeNarc, Simian, GroovyDoc, Hudson, Ant, Maven, Gant, Gradle, Spring, Guice, Spock, GMock and more. The talk is packed full of tips and examples for these and other tools.

We'll examine these tools: * EasyB: for writing acceptance tests * Cobertura: for checking code coverage * CodeNarc: for checking code style * Simian: for checking code duplication * GroovyDoc: for writing documentation * Hudson: for CI builds * Maven/Ant/Gant/Gradle: for build files * Spring/Guice: for dependency injection * GroovyMock/Spock: for mocking and testing * OSGi: for writing bundles

Developer practices for traditional and agile Java development are well understood and documented. But dynamic languages (Groovy, Ruby, and others) change the ground rules. Many of the common practices, refactoring techniques, and design patterns we have been taught either no longer apply or should be applied differently and some new techniques also come into play. In this talk, we'll relearn how to do agile development with dynamic languages.

What Java practices should you "unlearn"! Myths and truths about dynamic typing Interface-oriented style versus duck-typing vs chicken-typing Better patterns: Adapter, Builder, Delegation, Visitor, Strategy, Singleton, Immutable, Factories, Proxies and more Refactoring your Refactoring and Closure refactoring Applying functional style with closures and currying Pondering the relevance of the open-closed principle Do you need dependency injection when you have a MOP?

Testing can be a complex and thankless task. The technologies change so fast that your tools don't work as they should or you have to write lots of low-level boiler-plate code that is obsolete almost as soon as it's written. Your tests are brittle and hard to relate to customer requirements - you aren't even sure that you are testing the right things. Let's explore some techniques and tools for easing some of these burdens and try to move testing from tedious and hard to easier and fun!

We quickly sample a flavor of many techniques and tools including these topics: * Using Easyb for BDD flavored acceptance tests * developer testing using JUnit 4, TestNG, Instinct, Spock and GMock * writing domain specific testing languages (testing DSLs) * testing web applications with WebTest, Tellurium, Selenium and WebDriver * testing RESTful and SOAP flavored web services * testing databases with DbUnit * testing rich clients and GUIs with FEST * performance testing with JMeter * leveraging AllPairs, All combinations and other testing techniques * model driven testing

You've heard about how easy it is to build web apps with Grails. Maybe you've even seen the simple CRUD app in a blink of an eye, but do you want to see what Grails is really capable of? Then join us as we walk through the construction of a real web application with this powerful framework. Along the way we'll see how to take advantage of Grails' features like GORM, service classes, custom tags, and URL mapping.

You'll be amazed at how quickly you can become productive with Grails, not just because of scaffolding but because of the power of “Convention over Configuration,” sensible defaults, and the dynamic goodness of Groovy - all applied to a suite of the best tools in the industry, such as Spring, Hibernate, Tomcat, Ant, Sitemesh, JUnit, and more.

By Dave Klein

One of the most compelling features of Grails is it's custom tag libraries. Yet many developers, especially those coming from a JSP or JSF background, run from the room screaming when someone suggests creating a custom tag. Grails custom tag libraries are a powerful way to encapsulate business logic and keep code out of our pages. They are also great for declaring intent and making pages more readable. But here's the best part... they are ridiculously easy to create.

We will have a brief tutorial on creating Grails custom tags and then build a few to demonstrate just how easy it can be to tap into this powerful feature.

Software architecture is not static, and architectural shifts occur throughout the course of a project. Agile architecture is defined by our willingness and ability to embrace and accommodate architectural change. In this sense, agile architecture is both temporal and structural. The temporal aspect pertains to when decisions are made, and demands that the architect be flexible. The structural aspect demands that the architecture be flexible so that the team is able to accommodate change. In other words, our willingness to embrace change must be accompanied by our ability to accommodate change. Agile architecture demands both, and the absence of one precludes the presence of the other. In this session, we examine these two aspects of agile architecture. We'll discuss the concept of architecture throughout the lifecycle, and the activities performed by an agile architect. Extensive discussion is also devoted to modularity, and how large systems can be organized to increase flexibility, reusability, maintainability, extensibility, and testability. Numerous examples illustrating modularity patterns will be shown using OSGi and Spring DM. And we'll explore the inextricable link between temporal and structural agile architecture.

Understanding the domain within which customers evolve is a key factor in the success of a project. From this domain and its wealth of concepts, as software developers and architects, we can derive a design that is aimed at solving problems encountered in the day-to-day business.

So far, we mostly solved these brainteasers with computer science paradigms like Object-Oriented Programming, n-tier architectures, or with tools such as rules engines to stay close to the domain at hand. However, with the advent of dynamic languages, a new era has come to let you create languages taylored to a given domain of knowledge, allowing you to share a common methaphore of understanding between developers and subject matter experts.

Groovy, the popular and successful dynamic language for the JVM, offers a lot of features that allow you to create embedded Domain-Specific Languages. Closures, metaprogramming, operator overloading, named arguments, a more concise and expressive syntax, are elements of Groovy you can take advantage of to create your own mini derived language.

The purpose of this presentation is to show how to write such DSLs in Groovy, discovering in turn those various techniques, with pratical and concrete examples taken from real-life projects leveraging Groovy DSLs.

Enterprise application development is a gold mine for applications of AOP. There are many crosscutting concerns found in a typical enterprise application, ranging from well-known security and transaction management to application- and technology-specific concerns. Using AOP leads to implementations that are easy to understand and easy to change. When we combine Spring with AspectJ, we get a pragmatic AOP solution. This demo-driven session shows how to implement common functionality needed by typical enterprise applications, with a focus on web applications.

In this session, you will learn how to implement functionalities such as monitoring, exception handling, policy enforcement, transaction management, fault tolerance, and security. You should be able to take these ideas and implement them in your own projects and reap the benefits of AOP.

Traditional Enterprise Integration products (i.e., Enterprise Services Bus) promote a proprietary development and deployment model that requires a steep, costly organizational learning curve to successfully adopt. In addition, the more successful you are at adopting these development and deployment models - the more locked in to those proprietary products you become. What if Services Oriented Architecture could be be incrementally adopted in a lower risk, more agile way - led by your current Java developers and systems analysts? What if the end-result of this incremental adoption could simply be a re-factored version of your existing Java business application that is still fully portable across all java run-time environments?

Spring Framework, Spring Integration, and Spring Batch are lightweight, embeddable frameworks that serve to support the incremental adoption of SOA within your business applications, not complex, standalone middleware products that aim to control them (and ultimately you). This presentation will demonstrate how a legacy, vertically-integrated Java application can be re-factored toward a more flexible, modular service oriented architecture by the Spring developers you already have using the tools and platforms (tcServer, dmServer) they already know (and love).

Rapid assembly of a Spring web application requires an easy-to-use web framework for developers and web designers that makes it very simple to compose content into the user experience. High-end web sites, such as travel and e-commerce sites, may use Spring to integrate enterprise and back-end systems into the site, but can be let down by limited web frameworks, a lack of content services and a mass of disconnected JSP pages.

This presentation explains and demonstrates the SURF framework as a
new web framework founded upon the concept of Scriptable REST.
Scriptable REST quickens the pace for deploying REST controllers and remote application interfaces. It enables a scripting approach to web application assembly – lowering the cost of application development while moving the design of the web site from a purely technical exercise to one that can be built and extended by a web design team.

The SURF web framework improves upon existing web frameworks (such as Tiles or SiteMesh) by offering an easier means for defining and reusing site elements such as pages, templates, layouts, components and chrome. SURF provides remote connectivity management as well as integration to open standards, such as the OASIS CMIS interoperability standard so as separate content management from the application development process.

Using the standard Spring Pet Clinic application as a starting point, this session shows how that application can be developed using SURF’s Scriptable REST architecture. It demonstrates how content is externally managed, deployed and integrated into the application by the end user. It also shows how the application can be extended using scripting that complements the Spring MVC framework.

This presentation will go over how to use Spring Web Flow in Grails to make easy to use page flow based applications.

One of the hottest new features coming out of the spring team is Spring Web Flow. With the 2.0 released recently, it will start to gain even more support. What is Spring Web Flow you ask? Simply it is a way one can easily construct the flow of the website without having to make the services aware of what page the service should forward to next. However, this is not just about controlling the flow, with Spring Web Flow one is able to keep state of the objects for the duration of the flow, one is able to stop someone from entering in the middle of the flow, and most importantly one can create alternate paths inside the flow. All of these features give your application added functionality that

Ever since Grails came out a few years ago it has grown in excitement and expectations. Grails allows an easy ability for developers to create applications in a faster pace. For Java developers it was even more exceptional because they were able to leverage technologies most were already familiar with, Hibernate and Spring. Especially interesting was the use of Grails Object Relational Mapping (GORM), GORM is the database persistence layer behind GRAILS. This allows for creating dynamic queries that are easily readable like "User.findByFirstAndLast(..)", which will generate a query to find by the columns first and last. Using queries like this makes it very quick and easy to create queries, especially with criteria queries. So what's the downside? We HAVE to use Grails. For some newer apps this may not be an issue. But a legacy application or an organization that does not want to jump down the dynamic path THAT fast it can be an issue. Well no more, with Grails 1.1 the ability to use GORM with a regular spring application is now realized.

In this presentation we will show how to use GORM in your normal day to day Spring app and how GORM will be able to cut down on development time and increase code cleanliness in your Spring application. We will cover how to use GORM and how to integrate GORM with a regular Java Spring app.

As with many technologies, the basics are easy. The hard part comes when the developer needs to do sophisticated integration, development, and testing as part of an enterprise application. A large enterprise application requires the developer to think of issues that affect the development, scalability and robustness of the application. This presentation will cover the advanced topics described below with a focus on the new persistence features in Spring 3.0 and JPA 2.0.

A large enterprise application often will have several sub-projects that each contain their own JPA persistence unit. This opens up a number of questions around how to organize the persistence units and how the code between sub-projects should interoperate. Developers will gain insight into these issues and will see a couple of solutions using live code examples. Many enterprise applications require integration with an application server's JTA mechanism. JTA integration allows for JPA components to work with container managed transactions and distributed transactions. A typical usage scenario for JPA & JTA is this: read from a database using JPA, perform some business logic, put a mess

The Amazon Elastic Compute Cloud (EC2) is ideally suited to running Java applications. It lets you develop using standard Java software packages such as Tomcat and MySQL and rapidly deploy applications on servers that are provisioned and managed via a web services API. And, with its pay as you go pricing model, Amazon EC2 enables startups to launch their application without any upfront investment in computer hardware and allows enterprises to reduce costs and become more agile.

However, because it is a cloud, some aspects of Amazon EC2 are very different than a traditional, physical computing environment. In this session you will learn about those differences and how they impact how you handle security, networking, storage and availability. We describe how to use EC2 and the other Amazon web services to develop and deploy Java applications. You will learn how to use EC2 availability zones to deploy highly available applications. We also discuss how to architect secure applications for Amazon EC2.

The Amazon Elastic Compute Cloud (EC2) is probably the best known web service from Amazon but it’s not the only one. There are other highly scalable and reliable web services that you can use in your Grails applications including the Simple Storage Service (S3), Simple Queuing Service (SQS) and SimpleDB, a non-relational database. Although, using these web services couples your application to Amazon, they let you build highly scalable applications without the pain and cost of having to develop your own infrastructure.

In this session you will learn how to use these web services. We describe the various open-source Java libraries for interacting these web services including JetS3t and Typica and how to integrate them into your Grails development model. You will learn about the benefits and drawbacks of these web services and their typical uses cases.

As a small company, it's often necessary to add new features to get the biggest customers to buy your product. Hyperic HQ was a large, enterprise application based on J2EE and Struts. When big clients came to us they frequently required feature additions to close the deal. Groovy gave us the power to say YES to these customers without making any invasive modifications to our code base, allowed us to scale up for extremely large customers, and gave us a new point of contact for community contributions.

In this talk, I'll describe patterns that Hyperic used to give customers specific one-off plugins to dynamically add UI screens, customize existing features, and integrate with external systems. In addition, I'll explain how to use Groovy to make supporting your deployed applications infinitely easier.

Spring 3.0 introduced the Spring Expression Language (SpEL), an extremely powerful yet succinct way to wire non-trivial values into Spring beans. In this presentation, we'll explore SpEL in great detail and see how SpEL opens up a whole new realm of bean wiring possibilities.

Spring's brand of dependency injection is quite awesome. But there are times when simple bean references and static values won't cut it. Sometimes it makes more sense to wire bean properties with values that are evaluated dynamically at runtime. That's where the Spring Expression Language (SpEL) comes in. SpEL is one of the most interesting of the many new features in Spring 3.0. With SpEL you can succinctly wire in values derived... ...from system properties ...mathematically ...from the values of other bean properties ...from the results of static methods ...from almost anything you can conjure up Previously, most of these types of wiring could only be accomplished with more XML confi

The road to application success does not end at deployment. In fact, an application's life is longer after development and initial implementation than it is before, and success is measured almost exclusively by the experience of the application's end-users. Perceived or real, poor application performance can have a lasting effect, and can negatively impact an organization's bottom-line. Measuring availability, key performance metrics, and having timely notification of issues reach the "right people" across the entire application stack is imperative.

In this session we will talk about the importance of a monitoring mindset through the entire "Build -> Run -> Manage" lifecycle of an application, how to identify key performance metrics across an application stack, and how to overlay responsibility work-flows for timely issue notification. The information and discussion is meant to be generally applicable, but specific examples will be imparted using the SpringSource HQ monitoring tool-set.

With its recent acquisition of Ehcache and the newly released Terracotta for Hibernate, Terracotta has built a line of distributed cache products that can help Spring developers build fast scalable applications with a lot less hassle.

In this presentation you'll learn how to get high performance and scale using Terracotta as the engine for Ehcache and Hibernate performance. Ari will walk you though the details of real customer applications where Terracotta has been used with Ehcache and Hibernate to achieve 30-90% database offload, 10 times the application throughput, and reduce application latencies to the single-digit millisecond range. Also, get insights into the Terracotta product roadmap and learn about some new features being built for Ehcache
