Hi All,
I am trying to read messages from openjms-0.7.7 using the ConsumeJMS Processor
but getting following exception:

I have configured the JMSConnectionFactoryProvider with the following
properties:
MQ ConnectionFactory Implementation
org.exolab.jms.client.JmsConnectionFactory
Actual
MQ Client Libraries path (i.e., /usr/jms/lib)
/user/nirmal/OpenJMS/openjms-0.7.7/lib
The lib directory for OpenJMS
I also tried org.exolab.jms.client.JmsXAConnectionFactory in the above #1
property but again the same exception logs.
Not sure if somebody tested the ConsumeJMS / PublishJMS processors with OpenJMS?
Thanks,
-Nirmal
