I am using WMQ 7.0.1 on Linux 64 bit. I am running a java program that reads WMQ queues in Bindings mode.

The error I am getting indicates it is linking to the 32 bit libmqjbnd.so instead of the 64 bit libmqjbnd.so.

The following is the test script:

Code:
usr/java/jdk1.6.0_21/bin/java  -Djava.ext.dirs=.:/opt/mqm/java/lib cpo.JmsServer XLINUXQM INAZA0


The following is the error I receive from the program:

Code:
[root@eX5A test]# ./t.sh
com.ibm.msg.client.jms.DetailedJMSException: JMSFMQ6312: An exception occurred in the Java(tm) MQI. The Java(tm) MQI has thrown an exception describing the problem.  See the linked exception for further information.

I have tried adding the /oopt/mqm/java/lib64 to the PATH statement, but have had no success.

How can I get WMQ to pick up the correct lib ?

Thanks

Thanks

However, when I applied the fix, as follows:


Code:
/usr/java/jdk1.6.0_21/bin/java  -Djava.library.path=/opt/mqm/java/lib64 -Djava.ext.dirs=.:/opt/mqm/java/lib cpo.JmsServer XLINUXQM INAZA0


I still get the same error:

Code:
bash-3.2$ ./t.sh
com.ibm.msg.client.jms.DetailedJMSException: JMSFMQ6312: An exception occurred in the Java(tm) MQI. The Java(tm) MQI has thrown an exception describing the problem.  See the linked exception for further information.
