If I understood your problem correctly, MyMDB listens to a topic on WebLogic, and you want to use an additional JMS destination provided by JBoss, defined in a deployed configuration file and identified by its JNDI name (by default, deploy/jms/jms-ds.xml only contains the configuration for the JMS provider and connection factories -- no data sources).
The easiest way is to let the container inject the JMS destination and a connection factory via its JNDI name (in JBoss the JMS destinations are configured by deploying xxx-service.xml files). On startup you can then initialize the connection, and perform cleanup as soon as the MDB is released.
The following examples shows injection (@Resource) and resource managemend (@PostConstruct and @PreDestroy). The JMS connection and destination is used in useJmsDestination(String) to send a text message.
public class MyMDB implements MessageListener {
@Resource(mappedName = "queue/YourQueueName") // can be topic too
private Queue targetDestination;
@Resource(mappedName = "QueueConnectionFactory") // or ConnectionFactory
private QueueConnectionFactory factory;
private Connection conn;
public void onMessage(Message m) {
// parse message and do what you need to do
...
// do something with the message and the JBoss JMS destination
useJmsDestination(messageString);
}
private void useJmsDestination(String text) {
Session session = null;
MessageProducer producer = null;
try {
session = conn.createSession(true, Session.AUTO_ACKNOWLEDGE);
producer = session.createProducer(targetDestination);
TextMessage msg = session.createTextMessage(text);
producer.send(msg);
} catch (JMSException e) {
throw new RuntimeException(e);
} finally {
try {
if (producer != null) {
producer.close();
}
if (session != null) {
session.close();
}
} catch (JMSException e) {
// handle error, should be non-fatal, as the message is already sent.
}
}
}
@PostConstruct
void init() {
initConnection();
// other initialization logic
...
}
@PreDestroy
void cleanUp() {
closeConnection();
// other cleanup logic
...
}
private void initConnection() {
try {
conn = factory.createConnection();
} catch (JMSException e) {
throw new RuntimeException("Could not initialize connection", e);
}
}
private void closeConnection() {
try {
conn.close();
} catch (JMSException e) {
// handle error, should be non-fatal, as the connection is being closed
}
}
}
I hope this can help you.
