[JBoss Messaging] - Piling thread count when it polls the queue.
by apk2072
For every 10 seconds my code calls the below method to poll for new messages, but the problem is, JBoss messaging implementation is internally creating a new thread whenever it executes the session.createConsumer(queue) statement. And thread count grows continuously as it polls, after some time it ends up with Out of Memory error.
Is it a bug in the JBM implementation or I am not doing it correctly? Please advice.
| public String pollForNewMsg() throws Exception
| {
| InitialContext ic = new InitialContext();
| ConnectionFactory cf = (ConnectionFactory)ic.lookup("/ConnectionFactory");
| Connection _jmsConn = cf.createConnection();
| Session session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
| Queue queue = (Queue)ic.lookup(queueName);
| javax.jms.MessageConsumer consumer = session.createConsumer(queue);
| conn.start();
| TextMessage msg = (TextMessage)consumer.receive(10);
| String text = msg.getText();
|
| consumer.close();
| conn.close();
|
| return text;
| }

I get several database deadlocks like the one bellow, when i am trying to stress my application.
I am using JBoss 4.0.5.GA with JBoss messaging 1.2.0GA configured to use MS SqlServer 2005 as a persistent storage.

[JBoss AOP] - Re: unable to resolve an AOP IllegalArgumentException
by kabir.khan＠jboss.com
In my experience, this error cannot occur unless your classes have already been woven with a really old version of AOP (as in the IDE) and deployed in jboss with a different version. Two things to try to check if this is happening
1) Run with EnableLoadtimeWeaving=false. If you still get the same error, your classes have been woven.
2) Go to the root directory of where your compiled classes are/where they are put into the .war and execute:
$javap org.acme.Foo
(substituting org.acme.Foo with the name of one of your woven classes that you want to check). If the class implements the Advised interface it has already been woven.
I am not familiar with the AOP IDE and AOP Builder, but here's a thought you might have the AOPC'ed classes hanging around in your project's output folder, with no rebuild having been done after removing the AOP Builder. Do a Project/Clean in Eclipse and see if that helps.
