Consuming a Webservice created on WAS 6.20

Hello,

is it possible to generate a client proxy automatically on WAS 6.40 for a WSDL-description which is generated with the Webservicebrowser on a WAS 6.20?

I tried to do this but when i test the proxy i receive the following fault-message:

Unexpected element -el=definitions ns= http://schemas.xmlsoap.org/wsdl/>

When i compare a generated WSDL document on 6.40 and a generated WSDL document on 6.20 i see that these documents are different. What is the reason for this differences?

Thanks for your help!
