this is my web wsdl

Got the same excepion today.

I found out that this was not about the wsdl, but about the reply message sent back from the server for the call. That was an html 500 error (in my case due to wrong login credentials in the endpoint url).

GroovyWS cannot parse that html return message.

Try to see your message flow with a message monitor, for example a tcpmon proxy on port 5555. Then run:
> groovy -DproxyHost=localhost -DproxyPort=5555 TestSiebel.groovy
to see the request and reply message. If an html message is the reply, then that is the problem.
