Subject: How to create an asynchronous in-out operation with WS-Addressing
Content-Type: text/plain; charset=UTF-8; format=flowed
Content-Transfer-Encoding: 7bit

Hi all,

I'd like to create a WebService using axis with asynchronous operations that 
have an output. I already read some documentation about asynchronous WS in Axis 
but I still don't know to which extent axis supports users there.

Currently I'm following the top-down approach, modeling the WSDL in Eclipse, 
then creating the server skeleton using wsdl2java.

The client of the service will be the Apache ODE Workflow Engine, which should 
provide an EPR when calling WS asynchronously.

For asynchronous operations I think there are two possibilities:

1. Create an in-only operation, as well as a second in-only operation in another 
WSDL, which represents the return path of the first operation's "out" message.

2. Create an in-out operation using an asynchronous message receiver in service.xml.


Is it even possible to provide an in-out operation that can be called either 
synchronous or asynchronous (without providing two version in the WSDL), 
depending on the client supplying an EPR or not?

Best regards,
Jens
