Samisa Abeysinghe updated AXIS2-3262:
-------------------------------------
Component/s: (was: wsdl)
codegen
> WSDL2Java generates incorrect Exception stubs
> ---------------------------------------------
>
> Key: AXIS2-3262
> URL: https://issues.apache.org/jira/browse/AXIS2-3262
> Project: Axis2
> Issue Type: Bug
> Components: codegen
> Affects Versions: 1.3
> Reporter: Oleg Efimov
> Assignee: Amila Chinthaka Suriarachchi
> Priority: Critical
>
> I'm going to show simple example of the problem.
> First, I create a test service:
> --------------------------------------------------------------
> test.axis.SoapService
> package test.axis;
> public class SoapService {
> public void test() throws RemoteException {
> }
> }
> ---------------------------------------------------------------
> test.axis.RemoteException
> package test.axis;
> public class RemoteException extends Exception{
> public RemoteException() {
> }
> public RemoteException(Throwable cause) {
> super(cause);
> }
> public RemoteException(String message) {
> super(message);
> }
> public RemoteException(String message, Throwable cause) {
> super(message, cause);
> }
> }
> ------------------------------------------------------------------------------------------------------------------------------------------------------------------
> I deploy it on tomcat5.5 on context /axis, web.xml is:
> ---------------------------------------------------------------- web.xml
> <?xml version="1.0" encoding="UTF-8"?>

> ------------------------------------------------------------------------------------------------------------------------------------------------------------------
> This task generates the following file tree inside testaxis/src/test/axis
> folder:
> ----------------------------------------------------------
> /stub
> RemoteExceptionException0.java
> Soapservice.java
> SoapserviceCallbackHandler.java
> SoapserviceStub.java
> /xsd
> ExtensionMapper.java
> RemoteException.java
> Exception.java
> RemoteException0.java
> ------------------------------------------------------------------------------------------------------------------------------------------------------------------
> So, we've got plenty of exception classes here. To briefly describe their
> relations in UML-like style, I can say:
> test.axis.stub.RemoteExceptionException0 HAS test.axis.RemoteException0 IS
> java.lang.Exception
> test.axis.RemoteException0 HAS test.axis.xsd.RemoteException
> test.axis.xsd.RemoteException IS test.axis.Exception
> Stub method test() is reported to throw
> test.axis.stub.RemoteExceptionException0, which is simply
> java.lang.Exception, not an AxisFault, so really in case of RemoteException
> on server I'll get just AxisFault with message preserved, not any specific
> RemoteException I've wanted.
> I believe, only one exception stub should be generated, called
> RemoteException, and it should subclass AxisFault.
> PS Damn, I really hope someone will read it :)
