There is almost no information to go on here and therefore no way to answer with any confidence. Instead, I'll provide a diagnostic process and hopefully you will find the problem. Note that in the future if you have similar issues, it would help to list the diagnostics you have already tried so that people responding can narrow down their answers.

In order for this to work, the QMgr must be running a listener, have a channel defined and available, have authorizations set up to allow the connection, and be able to resolve the queue or topic requested. With that in mind, the things I normally check and the order I check them in is as follows:

  1. Is the QMgr running.
  2. Is the listener running? On what port?
  3. Can I telnet to the QMgr on the listener port? i.e. telnet mqhost 1414.
  4. Is the channel defined? If so, is it available?
  5. Do the sample client programs work? In this case, amqspubc is the one to try.

There are other considerations and if all of the above work, it is time to look into the client code and configuration, the versions of the client and server, authorizations, etc. But until you know that the basic configuration is in place to support a client connection (which was not indicated in the question) then these are the things to start with.
