New Course on Web Services for WebSphere®

Capstone today releases a new course which lays out the state of the art of developing web services using IBM WebSphere® 6.1. Course 561-WS, "Developing Web Services on WebSphere," springs from our hugely popular Course 561 on JAX-WS and JAXB web services, and has been completely reworked to support the particulars of WAS.

And this was no mean trick! WebSphere 6.1 does implement JAX-WS and JAXB, but does not implement the standard for web-services metadata on Java EE 5 -- often known as JSR 109. And there are other standard behaviors not yet available in WebSphere 6.1. This amounts to a partial implementation of the prevailing standards, and it means that Course 561-WS is a lot more than a simple port of the standard course.

So we discuss the standards (which are supported in WAS 7) as a future direction, but focus on practical applications under WebSphere, and point out server-specific ways of doing certain things along the way. In a week, the course covers:

  • Interoperable standards: SOAP, WSDL, UDDI, WS-I BP
  • Java EE standards: JAXB, JAX-WS, SAAJ
  • WSDL-to-Java and Java-to-WSDL development (what IBM likes to call "top-down" and "bottom-up")
  • Headers and handlers
  • Low-level implementation with Provider/Dispatch APIs and JAXP

A RAD7 overlay is available for the course, similar to the Eclipse overlays we provide for our usual Java-EE courses.
