Hi all,
Urgent help needs!!!
I have succesfully deployed JMSReceiver MDB into JBOSS3.2.3.
1> Code:
package netsure.dat.adapterEngine.receiver;
import javax.ejb.MessageDrivenBean;
import javax.jms.MessageListener;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.ejb.MessageDrivenContext;
import javax.jms.JMSException;
import javax.jms.Message;
import java.util.logging.*;
/**
*
* @author netsure
*/
public class JMSReceiverMDB implements MessageDrivenBean, MessageListener {
private MessageDrivenContext mdc = null;
static final Logger logger =
Logger.getLogger("netsure.dat.adapterEngine.receiver.JMSReceiverMDB");
public JMSReceiverMDB() {
addLogger();
logger.info("In MessageBean.MessageBean()");
}
private void addLogger(){
try{
FileHandler handler = new FileHandler("//home/netsure/JMSReceiver.log");
logger.addHandler(handler);
}
catch(Exception e){
e.printStackTrace();
}
}
public void setMessageDrivenContext(MessageDrivenContext mdc) throws
javax.ejb.EJBException {
logger.info("In MessageBean.setMessageDrivenContext()");
this.mdc = mdc;
}
public void ejbCreate() {
logger.info("In MessageBean.ejbCreate()");
}
public void onMessage(Message inMessage) {
TextMessage msg = null;
try {
if (inMessage instanceof TextMessage) {
msg = (TextMessage) inMessage;
logger.info("MESSAGE BEAN: Message received: " + msg.getText());
}
else {
logger.warning("Message of wrong type: " +
inMessage.getClass().getName());
}
}
catch (JMSException e) {
logger.severe("MessageBean.onMessage: JMSException: " +
e.toString());
e.printStackTrace();
mdc.setRollbackOnly();
} catch (Throwable te) {
logger.severe("MessageBean.onMessage: Exception: " + te.toString());
te.printStackTrace();
}
}
public void ejbRemove() throws javax.ejb.EJBException {
logger.info("In MessageBean.remove()");
}
}

.
And I use a session Bean JMSPublisher to publish message onto the topic the MDB
listerning on. In term of the trace, Messages are published. While, no message is
received on MDB. Why?? ANy idea?
Great Apprecation.
