I had reason to visit and download the latest version of the Eclipse WTP (Web tools Project). This has grown substantially during the last 12 months and there are some nice tools. One in particular is the Web Services Explorer, which provides the facility to view WSDL files and also invoke operations defined within the WSDL document. It automatically renders a form to accept user input and also presents the response in another pane. Very useful for testing deployed web services. Thanks Alex Boisvert for the tip.

I was able to use it to exercise the Work Manager service, which I am currently looking at again.
