Verify Error while trying to establish a connection to Websphere queue from a JBoss Server

Question

While trying to intialize the ConnectionFactory from a jobScheduler (running in jboss-5), to websphere queue, I get the below exception

Since it is throwing classNotFound, i went and checked the lib folder and the class is present in the jar named "ibmorb.jar". (Not sure why ClassNotFound is thrown)

This is the naming factory which is getting initliazed in the IntialContext

com.ibm.websphere.naming.WsnInitialContextFactory

Please help me on this

The jar and context factory mentioned would tend to indicate that the WMQ client was borrowed from a WebSphere Application Server install rather than using the stand-alone WMQ client installer. If that is the case you can likely fix this quite easily by installing the stand-alone client. You can obtain this free (with registration) as a SupportPac. These are by version so you have your choice of:

V7.1 client is SupportPacMQC71 (Preferred)
V7.0 client is SupportPacMQC7
V6.0 client is SupportPacMQC6 (Out of support as of September 2012)

Note that installing the client from the IBM-supplied installer provides a number of additional features such as diagnostics for tracing, version display, initial verification test code, sample source code, etc. This is the method of install that IBM will support so even though you can get it to work by copying the jars from the WMQ server install, using IBM's media is recommended.

Note also that the packaging of the Java and JMS classes has changed between versions. It is important to know which version that you are using and refer to the corresponding docs for CLASSPATH and other config options. The v7.1 implementation has many functional improvements and is the only version that will take advantage of the features on a v7.1 QMgr. However it will connect to any version QMgr so if this is new development, try to use the v7.1 client now so that you don't end up needing to upgrade down the road.

The Infocenter links for each version of the client are:

V7.1 Infocenter Environment Varariables for JMS & Installing classes for JMS
V7.0 Infocenter Clients and Using Java manuals
V7.0 Infocenter Clients and Using Java manuals

One of the utilities supplied with the IBM installer is the setmqjmsenv script (and setmqjmsenv64 when installing the 64-bit client) in the java/bin directory. You can look here to determine the CLASSPATH and other environment variables needed for your version of WMQ Client Classes for Java.

Solution with which I resolved this is

Deleted the IBM jars, if it is placed twice in the application
If the same jars are placed separately in two applications (running in the same server), then, placed the jar files in jboss's lib folder (to
avoid redundant)
Placed jacorb.jar in jboss's lib folder, in order to avoid the usage of java's default corba package

I followed these three steps and I didn't get this error !!!

Thanks for all your answers and efforts !! :-)
