I am new to WebSphere MQ and JMS. I have installed the MQ Server and the client on Windows Server 2003. When accessing queues locally from java client in CLIENT mode everything works fine. When trying to run the same code from other machine that doesn't have MQ server I receive the Security exception. I am not sure where and what needs to be configured. The code to start the connection is this:
JmsFactoryFactory ff = JmsFactoryFactory.getInstance(WMQConstants.WMQ_PROVIDER);
JmsConnectionFactory cf = ff.createConnectionFactory();
cf.setIntProperty(WMQConstants.WMQ_PORT, port);
cf.setStringProperty(WMQConstants.WMQ_CHANNEL, channel);
cf.setStringProperty(WMQConstants.WMQ_HOST_NAME, hostName);
cf.setIntProperty(WMQConstants.WMQ_CONNECTION_MODE, connectionMode);
cf.setStringProperty(WMQConstants.WMQ_QUEUE_MANAGER, queueManager);
connection = cf.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
sendToDestination = session.createQueue(sendToQueueName);
receiveFromDestination = session.createQueue(receiveFromQueueName);
producer = session.createProducer(sendToDestination);
consumer = session.createConsumer(receiveFromDestination);
connection.start();
===============================================
This is the exception that is thrown:
Exception in thread "main" com.ibm.msg.client.jms.DetailedJMSSecurityException: JMSWMQ2013: The security authentication was not valid that was supplied for QueueManager 'QM_mike' with connection mode 'Client' and host name '192.168.0.147'.
Can somebody help me? |

Be prepared to spend a little time on this issue because it is related to security.
The server-side channel needs to present a username to the queue manager when your client connects. The rules on how it determines that username are many and involved.
Search the forum and the internet for the number 2035 in combination with mq and client. Search for MCAUSER and SVRCONN.
Follow the username data through from client to queue manager.
Client OS logged in user -> MQJMS code -> MQ channel code -> MQ queue manager -> Server OS knowledge of users and its mapping to authorities.
Add to this that on Windows authorizations are stored against Windows SIDs not against a simple username or groupname.
I am a bit perplexed that the error message mentions "authentication" because this is unlikely to be what is going wrong. Authorization is more likely to be the important topic. Note that authorization and authentication are different and ought always to be used correctly and distinctly in the MQ manuals and error messages.
I hope this begins to help but sorry it doesn't represent a direct answer to your symptoms. |

As a new person on the forum you might also want to spend a little time reading the guidelines. It's considered rude to double post, and also to hijack other threads as here
