Ole Matzura has released soapui 1.0

soapui is a java-swing based desktop application for inspecting,
invoking and functional testing of webservices over HTTP. It is mainly
aimed at developers/testers providing and/or consuming webservices
(java, .net, etc). Functional testing can be done interactively in
soapui or within a automated build/integration process using the soapui
maven-plugin. soapui currently requires java 1.5 and is licensed under
the LGPL license.

some usage scenarios:

WebService Developers - debug your webservices and create automated
tests for validating functionality and compliance
WebService Integrators - inspect target webservices, test their
behaviour and validate their functionality.
WebService Providers/Brokers - provide your customers/clients with
sample soapui projects containing requests and tests that get them
started with your services.

P.S. I haven't done anything on it but as I think it's a great
application, it's worth the post in this group.
