This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
You can read the XML Schema,SOAP,WSDL, UDDI from RMH.
For API oriented topics I would prefer reading the JWSD tutorial from SUN. For topics like SAAJ, JAX-RPC,JAXR tutorial from SUN gives good material. RMH's material for these topics is kind of toooooooooo descriptive and time consuuuuuuuming. I would recommend reading the material from SUN tutorial for API oriented topics and then glancing through the RMH book.
