| What kind of java program? Is it bindings or client connection? Is the queue manager on the same machine or remote? Does the queue manager have a listener running (if you are client connecting)? What operating system and MQ version? If you can append the answers to these questions, it will help figure out what might be wrong. |

What connection mode are we using to connect to MQ (bindings or client connection)?
I have not seen your code but I am assuming you are running in MQ server not MQ Client mode.
Is the queue manager on the same machine or remote?
QManager CLEBUD05 is running on server CLEBUD05, so it is running on the same machine.
Does the queue manager have a listener running (if we are client connecting)?
Yes, the listener is running it is listening on port 1414
What operating system and MQ version?
Sun OS 5.8
MQ Version is 5.20
clebud05 $ mqver
MQSeries Version: 520
CMVC level: p520-CSD03G
BuildType: IKAP - (Production) |

try enabling the tracing like in chapter 7 Tracing MQ base Java Programs of MQSeries Using Java (MQEnvironment.enableTracing). Then you will see what happens in the constructor of MQQueueManager.
I had the same problem, because in the CLASSPATH was an older version
of com.ibm.mq.jar. LIBPATH (LD_LIBRARY_PATH on solaris/linux) pointed to a lib directory of the new version. So an unsatisfied link error inside the
constructor occured. This error is NOT given to the outside by an exception !!!! So the call will hang ! |
