STP is offering developer support for JAX-WS development and SCA/Java development. This are Java 5 annotation-driven specifications, so we need to have some things in place for each:

1. Annotation jar files that contain the annotation declarations used. The STP annotations processor will use these and the JDT 
    to help developers become more productive with the technologies.
2. Tools jar files that contain code generation tools for the runtimes, including WSDL generators, Java generators, etc.

The two runtimes we are targetting for Europa are [CXF] and [Tuscany]. Here are the jars required for each:
