WSDL2Java

Question

Does anyone have much experience with WSDL2Java.... I created a .wsdl file and when I try to use WSDL2jAVA i get this error:
java org.apache.axis.wsdl.WSDL2Java MYWSDL.wsdl
{http://www.w3.org/2001/XMLSchema}int already exists
{http://www.w3.org/2001/XMLSchema}int already exists
{http://www.w3.org/2001/XMLSchema}string already exists
java.lang.NullPointerException

I have no idea how to trace this back to its source.
Here is my current .wsdl file... please tell me if you see anyhing

Hi there,
did you find any solution to this? I'm facing the same error and I really can't tell how to solve it.
Using Axis' WSDL2Java Tool with the following .wsdl file, I get a NullPointerException.
<wsdl:definitions xmlns:apachesoap="http://xml.apache.org/xml-soap" ...>
  <wsdl:import namespace="http://xml.apache.org/xml-soap"/>
  <wsdl:message name"storeAttachmentRequest">
    <wsdl:part name="content" type="aachesoap:Multipart"/>
  </wsdl:message>
  <wsdl:portType name="TestService">
  </wsdl:portType>
  <wsdl:binding name="TestServiceSoapBinding" type="impl:TestService">
    <wsdl:operation name="storeAttachment">
      <wsdl:input>...</wsdl:input>
      <wsdl:output>...</wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="TestServiceService">
    <wsdl:port name="TestService" binding="impl:TestServiceSoapBinding">
      <wsdlsoap:address location="http://localhost:8080/axis/services/TestService"/>
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>The Exception starts with:
at org.apache.axis.wsdl.symbolTable.SymbolTable.getURL(SymbolTable.java:590)
Does anyone know, what am I doing wrong? Did I forget to define any parameter?
Any help would really be appreciated!
Thanks a lot in advance!
