Professional BlazeDS: Creating Rich Internet Applications with Flex® and Java®

Let me start with an effortless but a limited way to integrate Flex and JPA/Hibernate. This time, the sample application that maintains a list of open source software products and its contributors will have a Flex interface.

• On clicking Next, a new screen is presented to you. This new screen allows inputs for J2EE settings, compilation options, and the output directory. Figure 7-11 shows the details. I selected JBoss AS 4.2 as the deployment environment and point to blazeds.war version 3.2.0.3978 archive file as the Flex WAR file.
