Hi developers,
I have created a WS with some WebMethods running on Jboss as an Eclipse Dynamic Web
Project. I am doing that with the annotations from javax.jws.*.
Now, it is possible that a method needs some time to reply to a clients call. The client
could stop waiting for the reply by setting a timeout value on the WS call like:
client:
// a very short time to test the error
| int timeout = 10; // in ms
|
| // set the timeout property
| Map<String, Object> ctxt = ((BindingProvider)service).getRequestContext();
|
ctxt.put(com.sun.xml.internal.ws.client.dispatch.impl.protocol.MessageDispatcherHelper.REQUEST_TIMEOUT,
timeout);
|
| // now call the WS method
| result = service.myMethod(number);
If now the client stops waiting for the reply and after some time my serverside method
wants to return its result to the client it fails with a java.net.SocketException
'Broken Pipe'. Unfortunately my servermethod finished successfully without getting
known of the failed communication. The exception can only be seen in the jboss log.
Is there a common way to get known of the clientside connection reset within my serverside
method? Does the WS-Framework provide any concept to manage such a race condition in an
elegant way?
Or have u any other ideas on how I could solve my problem? I need to know, that the client
has not recieved my result, cause in that case I need to rollback some actions that have
been done on server side.
