No ManagedConnections Available!

[r_kumar]

Hi folks,

I am using the java:/JmsXA connection factory to achieve transaction feature in JMS. I am publishing the messages from a EJB for every operation perfomed via the same (ejb) to a particular Topic. When the amount of clients using the EJB this is less then there seems no problem. But when the number of clients gets increased then i am running into all sort of problems. I see the below mentioned exception in the logs printed contiounsly,

Caused by: javax.jms.JMSException: Could not create a session: javax.resource.ResourceException: No ManagedConnections Available!
at org.jboss.resource.adapter.jms.JmsSessionFactoryImpl.createTopicSession(JmsSessionFactoryImpl.java:164)

Below is the code snippet used for publishing the message,

try
{
myConnection = fact.createTopicConnection();
topicSession = myConnection.createTopicSession(true, 0 );
topicPublisher = topicSession.createPublisher(myTopic);
//Construct the Message
ObjectMessage message = topicSession.createObjectMessage();
message.setStringProperty("cause", cause);
message.setObject(obj);
//Publish the message
topicPublisher.publish(message);
topicSession.close();
}
catch (JMSException jmse)
{
throw new MyException("JMS Exception occured while publishing a message", jmse);
}

Please let me know when and why the above mentioned exception is thrown and what should done to overcome this.

Note: Jboss version is 3.2.1

Thanks ,
Pravin

You don't need to create a new connection for each and every message you want to send.

To be transactionnal you need to create a new session though

BTW, your code create a connection but it does not close it ... That's normal you got those exceptions
