SOAP Monitor

Came across this brilliant tool for monitoring SOAP inbound/outbound messages:

http://java-source.net/open-source/web-services-tools/membrane-soap-monitor

This is more like a tunneling software, but purely for SOAP monitoring. It formats requests/responses for easiness.

YOu could use the SOAP-UI plugin for eclipse, but its quite heavy. One good thing I liked about SOAPUI eclipse plugin is its ability ot crete Junit test case from WSDL.
