I've set up an AS system and have deployed an analysis engine to it. I've sent test documents through the queue successfully using runRemoteAsyncAE.sh script. Afterwards, I made a test program to send CAS that I auto generate. Watching the queue, it looks like the CAS reaches to the delegate and gets processed. However, when I use uimaAsEngine.sendAndReceive(CAS), it seems to just sit there waiting for a return. If I use uimaASEngine.send(CAS) I get a CannotResolveClassException regarding uimaContextPath. I can't seem to find reference to setting a uimaContextPath in the docs or in the example script. When I stepped through the code execution, I find that that the exception is thrown at:
com.thoughtworks.xtream.converters.reflection.AbstractReflectionConverter Class type = implicitCollectionMapping == null ? determineType(reader, fieldExistsInClass, result, fieldName, classDefiningField) : implicitCollectionMapping.getItemType(); when the fieldName is "uimaContextPath". It works fine for the first child where fieldName is "name". What does this error mean? I am calling the service using the example in the guide: Map<String, Object> appContext = new HashMap<String, Object>(); appContext.put(UimaAsynchronousEngine.ServerUri, "tcp://${Broker}:61616"); appContext.put(UimaAsynchronousEngine.Endpoint, "StanfordEngineQueue"); appContext.put(UimaAsynchronousEngine.CasPoolSize, 1); uima.addStatusCallbackListener(new CallbackListener()); uima.initialize(appContext); for (int i = 0; i < 1; i++) { CAS cas = uima.getCAS(); cas.setDocumentText("This is just a test, Sam."); uima.sendCAS(cas); System.out.println("Sent CAS."); } And the callback listener is pretty much a copy of the callback listener in the runRemoteAsyncAE.sh.
