Here is an overview of the issue:
---------------------------------------------------------------------
        Key: AXIS-1554
    Summary: attempting to use incompatible return type - method getCause()
       Type: Bug

     Status: Unassigned
   Priority: Blocker

    Project: Axis
 Components: 
             WSDL processing
   Versions:
             current (nightly)

   Assignee: 
   Reporter: Andrei Iltchenko

Environment: JDK 1.4.X

Description:
WSDL2Java's bean and fault writers are oblivious to the fact that java.lang.Throwable and org.apache.axis.AxisFault, which always serve as base classes for service specific exception classes that it generates, have a certain set of properties. So that when we are dealing with a fault part that refers to a complex type like the one defined below:

<complexType name="MyException">
  <sequence>
    <element name="cause" type="xsd:string" /> 
    <element name="message" type="xsd:int" /> 
  </sequence>
</complexType>

WSDL2Java gemerates Java code that violates the semantic rules of Java:

MyException.java [36:1] getCause() in 
mypackage.myexception cannot override getCause() in 
java.rmi.RemoteException; attempting to use incompatible return type
found   : java.lang.String
required: java.lang.Throwable
    public java.lang.String getCause() {
                            ^
