[axis & wsif?] User-defined exception handling

[Rhett . DeWall]

Couple of questions:

I have an EJB that throws a user-defined exception named "userException"
Java2WSDL produces WSDL with the following information:

   <wsdl:message name="UserException">
      <wsdl:part name="fault" type="tns1:UserException"/>
   </wsdl:message>

   <wsdl:operation name="userException">
       <wsdl:input name="userExceptionRequest" message
="impl:userExceptionRequest"/>
       <wsdl:output name="userExceptionResponse" message
="impl:userExceptionResponse"/>
       <wsdl:fault name="UserException" message="impl:UserException"/>
   </wsdl:operation>

When the WSDL is generated, the following message is produced:

     createWSDL:
          [echo] Creating WSDL...
          [java] Feb 25, 2003 9:54:36 AM

1)  What does this really mean, and is it expected?

2)  The EJB implementation simply throws a new user exception, i.e., throw
new userException("some message");  Is Apache-AXIS supposed to map this
into a SOAP Fault?  That is not happening, and I am able to catch the
exception versus detecting a fault.  Also, I am using WSIF, but am not sure
if AXIS or WSIF if responsible for the mapping.

Thanks.
