Hi Jaroslaw, I tried my Example with the RoomNumberAnnotator service - it worked because it is a primitive service. I only have problems with aggregates defining delegates. I tried the Deploy_MeetingFinder.xml in the example folder, but the service doesn't work. I have to check the Exceptions.
In the attachment you can find the test client. The WorkerThread is a copy of the RunRemoteAE example shipped with the uima relase. The MultiThreadedTestClient creates the threads. thx Dietmar On Wed, Dec 8, 2010 at 2:52 AM, Jaroslaw Cwiklik <[email protected]> wrote: > I've created a multi-threaded application that uses a > BaseUIMAAsynchronousEngine_impl instance per thread.
