WSDL documents and browser-based clients for using the service are provided for all test suites. A directory of endpoints for each implementation is maintained on the lab site.

XMethods ( maintained Round 1, conducted in June 2001. The SOAPBuilders interoperability activity is now in Round 2, maintained by Bob Cunnings of White Mesa ( For each round, XMethods and White Mesa provide lists of implementations and WSDL documents that have been tested and document the test results. Based on this information, you can determine the state of ...
