This session will dive straight into the middle of a real-world open source SOA implementations, showing how all the facets of how the SOA Big Rules are attained within the solution. This will cover an in-depth walkthrough, by example and demos, of: How to implement large XML Schema-driven document/literal Web services using partly Java EE 5 and partly J2EE 1.4; How security is enabled through certificate-based authentication with WS-Security; How the services are orchestrated with WS-BPEL; and how JSR-168 portlets leverage the end-user experience and how these are exposed using WSRP. The solution is based strictly on open source software and a guide for picking the right frameworks and the right products in the myriad of these will be addressed as well. Prerequisites: Knowledge of Java technology, IDEs, XML, and an interest in SOA.
