RE: Question on user exception handling on autogenerated clients

[Choi Jongjin]

Hi, Michael.
Handling service-specific exception is implemented in Axis. 

In the generated code, 

        java.lang.Object _resp = _call.invoke(new java.lang.Object[]
{new java.lang.Integer(in0)});
        if (_resp instanceof java.rmi.RemoteException) {
            throw (java.rmi.RemoteException)_resp;
        }
        else {
AFAIK, _call.invoke() returns RemoteException (AxisFault) for propagated 
soap fault (server-side exception).

But Axis's implementation lacks of JAX-RPC 1.1 compatibility.
The generated exception classes are derived classes of AxisFault and 
require default constructor and setters which are not required in JAX-RPC 
1.1.

I guess this causes some problem.
If you use JAX-RPC 1.1 compliant exception classes (which have not default 
constructor 
and setter methods) in the client side, the deserialization of SOAP Fault 
message would fail.

I will add other comments in JIRA BEEHIVE-133.

Subject: Question on user exception handling on autogenerated clients

I'm autogenerating my clients using the wsdl2java ant task. It's working
really well.
One question regarding exception handling, though: When the server
throws a custom exception (subclass of java.lang.Exception), how does
the autogenerated client propagate the results in the response to the
caller? I had a look at the generated code and couldn't find any hooks
(see below). Is this not yet implemented? Thanks much.
Cheers,
