Look at the methods that are exposed. For the AsyncTaskService you will need to provide a handler that will be called when you receive a response. The SyncWrapper hide those handlers. About the expcetion: +String name = "client 1" ++UUID.randomUUID();+ +TaskClient client = new TaskClient(new HornetQTaskClientConnector(name, new HornetQTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));+ +Are you creating too much clients? When are you creating them? you should close them, if you are not using them anymore or reuse them.+ + + -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/745774#745774] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
