Part 1 (6 chapters) - Absolutely a waste of time, not worth a read. And the code examples are not related to JWSDP.
Part 2 (6 chapters) - Discusses on SOAP, UDDI and WSDL. The code discusses using a Older version of Apache SOAP and Apache Axis. The code needs a complete rewrite.
Part 3 - Discusses on JAXP, JAXB, JAXR, JAXM and JAXRPC. Good introductions but the JAXB chapter is based on DTD (which is obsoleted in the latest specs). JAXM and JAXRPC chapters just reproduces the Sun JWSDP tutorial...not much value addition.
Part 4 - Security, WSFL, WSIF (based on IBM Specs) currently these specs are obsolete no further releases.
It might've been a good book during 2002. The code and content needs an update to the latest specs and SOAP implementations.
