Hi,

I tried running a sample Java program integrated with MQAPIs on Compaq NAK. The program connects to queue manager, puts a message on to the queue and closes the queue and disconnects from queue manager.

Run of the program resulted in this error.

Exception in thread "main"
java.lang.UnsatisfiedLinkError: _MQCONN
at
com.ibm.mq.server.MQSESSION.MQCONN(MQSESSION.java,Compiled Code)
at
com.ibm.mq.MQQueueManager.connect(MQQueueManager.java,Compiled Code)
at
com.ibm.mq.MQQueueManager.(MQQueueManager.java,Compiled Code)
at MQSample.(MQSample.java,Compiled Code)
at MQSample.main(MQSample.java,Compiled Code)

any help would be appreciated...

Mohan

Looking at the MA88 Support Pac (how MQSeries Java support is distributed), I see the following supported platforms:

AIX
HP-UX 10-20
HP-UX 11
iSeries
Linux for Intel
Linux for S/390
Microsoft Windows 95
Microsoft Windows 98
Microsoft Windows NT
Microsoft Windows 2000
OS/390 V2R9 or higher (including z/OS)
Sun Solaris

I don't see your platform listed here. An MQSeries Java application has two modes of connecting to a queue manager:

o As a client
o As a locally bound application

Your messages seem to show that you are doing the latter. In this case, when you make method calls on the MQSeries Java classes, JNI (native code) is invoked. On your platform, the native libraries aren't installed (or don't exist).

I believe that you will succeed if you attach to your queue manager as an MQ client.
