Try adding a callback listener to the client via
public void addStatusCallbackListener(UimaAsBaseCallbackListener aListener)
There is try ... catch block in the client code
} catch (ResourceInitializationException e) {
state = ClientState.FAILED;
notifyOnInitializationFailure(e);
throw e;
}
which should notify your code of the problem. Are you deploying your
services in
the same process as the application? Or are these services deployed in their
own processes?
