I need to write a WSDL file to an existing web service which is provided to me by a colleague (it’s realized with Perl and SOAP::Lite). Therefore, I have a given format for the SOAP-response and need to define the service formally to be able to generate the code for a Java client to the service. To test the WSDL file against the service, I have been using both Eclipse’s Web Service Explorer and soapUI, to generate the code for the client I aim to use the Axis version distributed with Eclipse (1.3.x).
The definition file I have at the moment does work to access the service through soapUI and returns the desired SOAP-response which can also be asserted to be Schema compliant by soapUI, but if I generate code from it and try to run the code, things start to fall apart. Apparently, Axis does not recognize the defined types correctly and just creates members with an “anyType” type. The response can therefore not be serialized correctly which results in an exception by the SAX parser.
When I try to validate my WSDL file, I’m told it is not allowed to define an element with just another element as child, which I assume is the root of my troubles here. I tried to nest the “prefix_map” element into an anonymous complexType as the single item of a sequence, but now the Schema compliance assertion in soupUI fails. So how can I define the types for the response-message correctly for the given response?
This is the SOAP-response I get from the service:

Thanks for your help!
Ok. After you comment below I have refined my answer. I believe that Axis is looking for a concrete type for the element in question. Since it is not defined it assumes it is anyType, which it then has a hard time with. I would do the following:
Did that help any? That might make it more explicit and allow Axis to find what it wants.
