4.7. Conclusions

This chapter was a quick tour of WSDL, SOAP, and Java/XML mapping. I looked at those topics from the perspective of SOA. The primary assumption is that you need to work with standards-compliant WSDL, XML Schema definitions, and Java classes as you build and deploy SOA components as Web services. This assumption is at odds with JWS in a few places. To demonstrate this, I showed a couple of examples of common integration problems that have no straightforward solution using JAX-WS 2.0 and JAXB 2.0.

The purpose of pointing out these limitations has less to do with criticizing JWS than with pointing out how difficult SOA can be. In the last chapter of this book, I cover the SOA-J Application Framework and outline a WSDL-centric approach to building SOA components from Java that might provide solutions to some of these limitations.
