When I try to do a lookup of JMS Queue , I get the following error:

Could not create JNDI API context: javax.naming.NoInitialContextException: Cannot instantiate class: [Root exception is java.lang.ClassNotFoundException:]

My Code is as follows:

Can any body let me know where I am going wrong? Do I need to set any classpath for it to work?

The jar containing this file seems to not be on your classpath:

Find that class, and you should be good.

Which server version you are using there? if 6.1 then check properties might be you need this :

< !-- IBM ORB Properties -->
property name="org.omg.CORBA.ORBClass" value=""

else check for that perticular class and load thar JAR to classpath.

good luck ...

I have this problem too, and I am trying to configure WAS 6 and 7 to use Apache ActiveMQ to create and use a Queue.
The code I am using is pretty similar to the one posted here in the first post, and I get an error when the code reaches this line:

This is the error:

The code above runs on Websphere where I have defined a QueueConnectionFactory and a Queue named "jms/systemMessageQueue" which exists on ActiveMQ (up and running).

I really don't understand why this happens, even if I tried to add the jar file to the classpath as suggested.

Can somebody help me please?

You need to add MQ client jars to your app classpath. You can find some MQ client jars inside the MQ connector in WebSphere at ${WEBSPHERE_HOME}/AppServer/installedConnectors the MQ libs are inside the .rar file called: wmq.jmsra.rar

Ok, it seems that it was a bug of activemq. The snapshot version 5.8.0 seems to be bug free as regard such problem.
I agree. Here's the link:
