This behavior is random, not occurs always. In the most of the simple programs and simple test case tested, after restart the UIMA-AS Broker without restart service uima-as, the instruccion to uima-as client "BaseUIMAAsynchronousEngine_impl.connectionOpen()" return "false" and correctly i initialize the client again.
The incorrect behavior is most frequently with many uima-as client instances. Is the case of my general application in which i have many service uima-as, and for each one creates one instace of uima-as client (BaseUIMAAsynchronousEngine_impl) and keep it alive to process all requests of the service uima-as. Is in this scenario with many instancies of uima-as client (BaseUIMAAsynchronousEngine_impl) in the same program (a monolithic application web in tomcat) where after restart the UIMA-AS Broker without restart any service uima-as, many uima-as client returns "true" to the instruccion "BaseUIMAAsynchronousEngine_impl.connectionOpen()" but them throw "javax.jms.IllegalStateException: The Session is closed" when proces the request. 2017-07-04 16:13 GMT-04:00, nelson rivera <nelsonriver...@gmail.com>: > One peculiarity is that, is a primitive annotator implented in c++, > but is deployed with de deployAsyncService.sh de uima-as directly. > > 2017-07-04 14:53 GMT-04:00, nelson rivera <nelsonriver...@gmail.com>: >> In my program main, i initialize a uimas-as client only once and I use >> this client to consume all requests to a displayed service uima-as. >> >> Before process a request i ask to uima-as client with: >> BaseUIMAAsynchronousEngine_impl.connectionOpen() >> and if the result es "false", i stop the uima-as client and initialize it >> again. >> >> With some steps, still undefined, but after restart the UIMA-AS Broker >> without restart service uima-as. >> The instruccion to uima-as client >> BaseUIMAAsynchronousEngine_impl.connectionOpen() return "true", but >> them i get a "javax.jms.IllegalStateException: The Session is closed" >> when proces the request. >> >> Wich is the best way to know when connections betewen cliente uima-as >> and ActiveMQ is broken? and i should restart uima-as client. >> >
