Spring 2.0 introduced support for Message-Driven POJOs meaning that it is now possible to receive JMS messages asynchronously and delegate the handling of those messages to simple objects even within a lightweight application running outside of any application server. If your POJO has a return value, it will automatically be sent to a response destination.

After a quick overview of Spring's JMS support, we will build a Message-Driven POJO sample application from the ground up. This will include sending a Message as a request and receiving a reply across separate JVMs. You will learn how to configure the Message-Driven POJO without writing a single line of messaging code. You will also learn how to configure the pool of concurrent consumers and integrate with Spring's transaction management. We will use the JMS namespace available as of Spring 2.5, and we will even explore the possibility of delegating to a Groovy-scripted object.

Spring's Portlet MVC framework is one of the major new additions in Spring 2.0, bringing the proven benefits of the servlet-based Spring MVC framework to JSR-168 Portlet development.

In this presentation, you will learn how to use Portlet MVC to develop enterprise portlet applications. It will cover the framework's architecture and API in a direct comparison with Spring MVC. It will also include a walkthrough of a sample portlet application with a detailed review of the implementation and configuration. Mark will highlight a number of the framework's compelling features as well as its integration with Spring Web Flow.
