Further Reading

Though a number of books have come out explaining SOAP and WSDL, the authoritative source continues to be the official specification documents themselves. You can find the specification documents for SOAP 1.1 at http://www.w3.org/TR/SOAP/ and WSDL 1.1 at http://www.w3.org/TR/wsdl. It is quite likely that SOAP Version 1.2 will become a W3C recommended standard by the time this book reaches you. In this version, the specification is broken into three documents—Primer, Messaging Framework and Adjuncts. The Primer gives a solid overview of SOAP and is worth reading. WSDL Version 1.2 is also likely to reach candidate recommendation status soon.

The definitive source of information for JAX-RPC is the official specification and Javadoc documentation. You can find both of these by following the appropriate links from http://java.sun.com/xml/jaxrpc/. Sun's Java site has a tutorial on Java Web Services with a chapter on JAX-RPC. This tutorial has good information, though it uses Sun's JAX-RPC implementation, and not Axis, for examples. For Axis-specific information, refer to the Axis documentation.
