Service Endpoint Interface and RemoteException question on the server

Question

Hello,
I would like to be able to log and track RemoteExceptions when the network goes down when an attempt to send a response back to the client. I understand that Weblogic will handle the RemoteException but especially on a network failure I would like to be able to resend the message or at least notify a group that the connection is down.
Can I have pointer on how to do this on the server as I'm sending back the reponse back to the client.
This is an example of what I would like to do:
public String getInformation(String xmlReq) throws RemoteException {
String xmlRes ="";
try {
xmlRes = doTask(xmlReq);
return xmlRes;
} catch (RemoteException remoteEx) {
handleCommunicationFailure(xmlRes); // do what I need to do
throw new RemoteException (); // send the exception back to weblogic
Yes, I'm new at this.
Thanks!

Please understand that Exception you're throwing from the body of your method you're creating the WS operation out of is mapped to SOAP fault. It is not meant to deal with network failure from the server side where your service endpoint is hosted.
Also, in case of synchronous WS invocation, when/if the network outage takes place during the invocation, the SOAP proxy will throw a SOAPException with such information, but it won't convey any error conditions reported from the service (after all, the network has been disconnected, and there is no way to send SOAP response or fault message)
On the server side, the service implementation business logic should/can not deal with network outage condition. However, on the client side, it's possible to have a retry-mechansim when network connection outage is temporary.
