[jboss-user] [JBoss jBPM] - Have a node wait for JMS message - Problem
Hello everyone,
I have a node in my process that I want to wait on a jms message. I'm using the
following code:
package ch.siesa.beyondfibre.jbpm.customer.delete;
|
| import javax.jms.*;
| import javax.naming.*;
|
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class WaitAction implements ActionHandler, MessageListener{
|
| private static final long serialVersionUID = 1L;
|
| Context jndiContext = null;
| ExecutionContext executionContext = null;
| TopicConnectionFactory topicConnectionFactory = null;
| TopicConnection topicConnection = null;
| TopicSession topicSession = null;
| Topic topic = null;
| TopicSubscriber topicSubscriber = null;
|
| public void execute(ExecutionContext ctx) throws Exception {
| System.out.println("Subscribing node to JMS topic...");
| this.executionContext = ctx;
| jndiContext = new InitialContext();
| topicConnectionFactory =
(TopicConnectionFactory)jndiContext.lookup("TopicConnectionFactory");
| topic = (Topic) jndiContext.lookup("topic/testTopic");
| topicConnection = topicConnectionFactory.createTopicConnection();
| topicSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
| topicSubscriber = topicSession.createSubscriber(topic);
| topicSubscriber.setMessageListener(this);
| topicConnection.start();
| System.out.println("Subscription ok, waiting !");
| }
|
| public void onMessage(Message message) {
| executionContext.leaveNode("success");
| }
|
|
| }
|
It is however throwing an exception:
11:09:44,983 ERROR [GraphElement] action threw exception: This method is not applicable
inside the application server. See the J2EE spec, e.g. J2EE1.4 Section 6.6
javax.jms.IllegalStateException: This method is not applicable inside the application
server. See the J2EE spec, e.g. J2EE1.4 Section 6.6
I have two questions :
- Is there a workaround this exception ?
- Isn't there a simpler way to have a node wait for a message ?
Thanking you all in advance :)
Regards
