forum khan [https://community.jboss.org/people/forum.khan] created the discussion "JBOSS Connection Issue with MQ" To view the discussion, visit: https://community.jboss.org/message/745063#745063 -------------------------------------------------------------- Hi,    Let me explain the scenario:    1. I will be sending the message to the JMS queue which is delivered successfully. In the mean time i will stop the server then it throws the exception marked in Red.    2. Next i will restart the server. Exactly after 5 mins it display's the message it got reconnected successfully which is marked in Green.    3. After it gets connected successfully again am able to send the messages successfully to the queue.     Now i like to understand the below points     1. How this is getting reconnected exactly after 5 mins, where is the configuration setting?     2. It is observed that if i disconnect MQ for the whole night without shutting down the JBOSS then next day my JBOSS will not able to reconnect to MQ and will not be able to process the JMS messages. Here I like to understand after shutting down and restart the MQ it used to connect automatically. But when its closed from the whole night, next day JBOSS is not able to identity the MQ. Is there any special configuration setting for this? The below message is from the console. *Console:* 20:06:59,380 WARN  [HttpRouter] Received status code '302' on HTTP mailto:org.apache.commons.httpclient.methods.PostMethod@a29bbd org.apache.commons.httpclient.methods.PostMethod@a29bbd request to ' http://localhost:8080/someservice http://localhost:8080/someservice. 20:09:02,441 INFO  [CNN_Connection_Factory] JMSCC3036:An exception has been delivered to the connections exception listener: ' Message : com.ibm.msg.client.jms.DetailedJMSException: JMSWMQ1107: A problem with this connection has occurred.
