Some notes I could later use.
A stack comparison of most (I don't see JAX-RPC) of the available Web Service stacks in Java: http://xfire.codehaus.org/Stack+Comparison
(Could be somehow biased since it's made by the guys that do one of the stacks).
https://metro.dev.java.net/ = JAX-WS+WSIT
JibX - fast XML processing tool, JAX-WS can't use it - it can only use JAXB.
SoapUI - cool tool for testing web services, as a standalone and as an eclipse plugin - www.soapui.org
WSIT - Java API for better integration with .NET WCF and the WS-I standards.
