Presentations

Choices in Mobile Application Development

With the rising prevalence of advanced mobile platforms such as iPhone, Android, and Web OS, the desire for rich mobile clients as another means of accessing enterprise services is becoming something that can no longer be ignored. In this session, we will explore the current mobile development landscape and discuss what you as a Spring developer can do to support this increasingly important paradigm. We will examine the benefits and tradeoffs of native mobile client development vs. web-based mobile client development, and we will explore some of the emerging cross-platform options such as PhoneGap. We will look at the various strategies for utilizing a Spring back-end with these mobile platforms, such as consumption of RESTful services, authentication and authorization via OAuth, and server-push style messaging.

Session Detail

Harnessing the power of HTML5

The role that server-side Java plays in a web application is rapidly changing due to the rising prevalence of high-performance JavaScript VMs and browser support for advanced HTML5 APIs such as Canvas, Web Sockets, and Web Workers. This session will show how a RESTful Java back end built with Spring can provide scalable rich data and services to complement a smart client-side framework such as jQuery, Dojo, or GWT and its use of the HTML5 APIs.

This session is aimed at experienced Java web developers. It will cover: -Rapidly building lightweight RESTful services with Spring 3.0 and Spring Roo to support rich HTML5 clients -How to carry over the concepts of Java EE APIs such as JPA and Bean Validation to a smart client -Async message-based communication over Web Sockets.

Rapidly Building Spring-powered Flex RIAs with Spring BlazeDS Integration and Spring Roo

Spring BlazeDS Integration has proven itself as a powerful tool for enabling rich Flex client applications to fully take advantage of the power and flexibility of Spring-based services. The latest release of Spring BlazeDS Integration and it's accompanying addon for Spring Roo make developing Spring-backed Flex applications easier and more productive than ever. In this session developers will learn the basics of the integration and will learn how to use the Roo addon build a rich application that leverages the remoting, security, and server-push capabilities of this simple-yet-powerful technology. Along the way, we'll cover the new features in Spring BlazeDS Integration 1.5, such as first-class support for AMF serialization of Hibernate entities, that make the Roo addon possible.
