Unknown namespace error when generating a client proxy

Question

We are using WAS 7.0 and I'm trying to generate a client proxy for an inhouse webservice via Object Navigator (SE80). When using the Wizard I get an error message from the Librabry Handler saying: "Unknown namespace: http://schemas.xmlsoap.org/soap/encoding".
A check by the colleagues who provide this Webservice says that the wsdl is ok.
Any idea for this error message?
Many Thanks.

Hi Michael,
the use of soapenc:Array is not supported. There are other ways to declare arrays:
-In a DESCRIPTION, array declarations MUST NOT extend or restrict the soapenc:Array type.
-In a DESCRIPTION, array declarations MUST NOT use wsdl:arrayType attribute in the type declaration.
-In a DESCRIPTION, array declaration wrapper elements SHOULD NOT be named using the convention ArrayOfXXX.
-A MESSAGE containing serialized arrays MUST NOT include the soapenc:arrayType attribute.
So you need to copy the WSDL file to a local file and edit it, afterwards, use it to generate the proxy.
Maybe you should have a look at the following url:
http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#refinement16556272
I hope this will help you to solve the problem.
