Hi,
I am using WPS6.2.0.3, MQ Series 7.0 and trying to send messages to certain queues using connection factory jndi. The probelm is while sending certain number of messages to queue my session got close. Below is the exception being faced:
J2CA0056I: The Connection Manager received a fatal connection error from the Resource Adapter for resource JMS$AXIS_CF$JMSManagedConnection@276303992@33. The exception which was received is javax.jms.IllegalStateException: MQJMS1024: session closed
Below is the code i am using to write messages on mQ Queue:
| Code: |
Connection con=null;
InitialContext ic;
ic = new InitialContext();
ds = (javax.sql.DataSource) ic.lookup(jndi);
con = ds.getConnection(userName, password);
System.out.println("Connection got");
ConnectionFactory s = (javax.jms.ConnectionFactory) ic.lookup("AXIS_CF");
Q = (javax.jms.Queue) ic.lookup(queueName);
conn = s.createConnection();
conn.start();
session = conn.createSession(true,Session.AUTO_ACKNOWLEDGE);
while(records < 10000){
MessageProducer producer = session.createProducer(Q);
TextMessage message = session.createTextMessage();
message.setText(xml);
producer.send(message);
records++;
}
|
Please help why session is being closed after certain messages. Thanks in advance[/code] |

I'd start by looking at why you create all those messageproducers and then i'd wander why they are not closed.
And then i'd ask the same question about why the other resources you use arent closed. |

| And then there's whole question of "where's the transaction boundary?". |

No error handling
No transaction boundary handling... a default of 10,000 msgs in a tran is too much as it leaves no other tran available (default max qmgr = 10,000)
No releasing of resources acquired....
Review your code, think about it, fix it and come back.
