Sending Exception To Client from AMI
in Help Center
I have a client application that calls a method on the server. Since this operation takes a long time, I spawn a new thread on the server.
During the life of the server's thread there are several Exceptions that can be raised. How should I pass those exceptions back to the client? Should I create a client callback method to pass an Exception or is there a better way?

If the operation spawns a separate thread then I assume that your server is using asynchronous method dispatch (AMD). In this case, you invoke ice_exception on the AMD callback object (from any thread) in order to report an exception to the client.
If the operation is not using AMD, then you must somehow arrange for the dispatch thread (not the spawned thread) to raise the appropriate exception. However, when a server is spawning worker threads you'll generally find that it's much easier to use AMD instead.
Hope that helps,
