Hi All,
We have a requirement to connect to c++ system from message broker JMS environment.we have set the configuration required for jms(binding file).
how can an external c++ program able to connect to MQ JMS environment
we are trying to use XMS fixpack provided by IBM but still we are getting some connection failures.it would be greatly helpful if could let us know any specifc libraries or dlls needs to be used to connect to c++ environment.
Thanks in advance

Even with the XMS support pack you need at a minimum the MQ Client installed on the machine. Did you try that?
Also connection failures mean little to nothing without more information:
OS and MQ level?
What was your connection setup?
What was the error message?
What was the MQ return code and MQ reason code?
Have fun

| Thanks for the reply.actually we have only installed XMS fixpack in the c++ environment side.we have the requirement to post messages and to retireve messages from JMS MQ queues.for this do we need to provide any dlls or external libraries to give to C++ folks? |

Thanks victor.once they have installed mq client do they need to do any configurations other than running the c++ program?
Please suggest if you have some c++ programs to get the messages from jms queues.
we have provided the ipaddress,port of mq,initial context factory and location of the bindings to the c++ folks.any thing other than this we need to provide to them to run the program.
actually we are very new for the connectivity with c++..please suggest.
Thanks
Viswanath. |

Maybe. The configuration in the manuals might be good.

There's no such thing as a JMS queue. There are WMQ queues accessed by Java apps using the JMS. There is sample code supplied with the product, and also at the top of this page. These address using C++ to access WMQ (perfectly valid) rather than the XMS you're talking about using.

The matching configuration on the sever side.

Decide if you want to use C++ or XMS. Advantages & disadvantages on both sides.

Yes, at a minimum for a client connection you need
- IP name / address of the MQ Server
- TCP/IP port the QMGR is listening on
- The name of the SVRCONN channel to use for the connection
Now I would expect that information to be in the QCF. In java you retrieve the configured qcf from the initial context. Don't know if XMS allows you to do the same. And if you are new to MQ I would suggest you work with filecontext as initial context (at least when using java).
Have fun
