I am sorry folks about the earlier post. The problem was cause I didnt knew the
working of jboss very well, I suppose, I may be wrong again. If someone with
good knowledge can confirm it that will be good. I know the solution now for
the post I have made.
Jboss Jms works on the ping pong concept that took a bit long time for me to
find out how exactly it worked. I knew there was a thread running behind which
carried out the ping pong thing.
If you see my code, I will stick and paste the part of the code where I
identified the bug
/**
* Send the given String as a JMS message to the testQueue queue.
*/
public void send(String msg) throws JMSException {
// Create a message
TextMessage message = queueSession.createTextMessage();
message.setText(msg);
// Send the message
queueSender.send(queue, message);
}
If you see in above code I was forwarding the Jms exception thrown as it is, by
the time the other part of program where it could catch the the exception and
do something needful, the separate ping pong thread which was running used to
throw its own exception. and I was getting the un-needed exception in my output
log so when I changed the code as follows, the error was finally resolved after
2 days for me hope i save someone elses time.
/**
* Send the given String as a JMS message to the testQueue queue.
*/
public void send(String msg) throws Exception {
try{
// Create a message
TextMessage message = queueSession.createTextMessage();
message.setText(msg);
// Send the message
queueSender.send(queue, message);
}catch(JMSException jmse){
try{
if (queueConnection != null)
queueConnection.close();
//throw my own exception other than JMSException
throw new NullPointerException();
}catch(JMSException jmse){
//for connection exception
}
}
}
what I am doing in my above i am catching the exception thrown at that very
moment at close the connection so the ping pong thread will stop functioning
and later I throw my own exception as I want a centralised place for exception
handling and wish to do something with that exception in my other part of
program..
Hope the query is resolved. If someone can check it it will be good
Thanks in adavance
