I was going through this post as I am receiving the same error in an attempt to generate the client stubs using the Web Service Client generator in MyEclipse.
The thread seems to suggest that we should use Web Service generation wizard to generate the client stubs as well. But this does not seem to be consistent with the features. There is a separate wizard for Web Service Client generation which fails with most Web Services even though the Test client generation during a WSDL first web service generation works.
Could you please provide direction as to what might be causing an error like this?
Thanks
