Hi. I am trying to connect to a Queue Manager via the MQ Client, but I am receiving a NullPointerException.

Any assistance would be much appreciated!

WebSphere MQ Version 7.5 (from client README.TXT file)

line of code:
JmsFactoryFactory ff = JmsFactoryFactory.getInstance(WMQConstants.WMQ_PROVIDER);

According to the instructions(http://www.ibm.com/support/knowledgecenter/SSFKSJ_7.5.0/com.ibm.mq.dev.doc/q031560_.htm), I only need to reference com.ibm.mqjms.jar in the class path. However, when I do that, I get a ClassNotFoundException, looking for class com.ibm.msg.client.commonservices.Trace (which does not exist in com.ibm.mqjms.jar ).

When I add to the class path all jar files in directory %MQ_JAVA_INSTALL_PATH%/lib, I get the following exception:

FDC called in uninitialized Trace module
