Thanks for the fast answer, but its the same problem. I added:
<wsdl:message name="GetCategoriesRequest"/>
to my wsdl. But an invokation produces:
java.lang.NullPointerException
at
org.apache.axis2.context.MessageContext.setEnvelope(MessageContext.java:681)
at org.apache.axis2.ProductStub.GetCategories(ProductStub.java:119)
at ProductTest.main(ProductTest.java:10)
Here is the new WSDL again:
