I am trying to create a userdefined node in Java which uses JMS to put a message. I know I can use the JMSNode . This is just to test a user defined node.

I create the Java Project , Plugin Node Project and Message flow project and able to successfully deploy the flow with the node to the broker.

I created a par file and added all the jar files required to the lib directory.


The code gets the QueueConnectionFactory by ldap lookup. It works fine when I use the same code in a Java client application .

But when I use it in the User defined node , the ldap lookup returns the object as javax.naming.Reference and giving me a classcastexception.
Any thoughts ? I added all the jar files in MQjava/lib to the par file lib directory.

Here is the code i used to get the type of object .

Code:

Object obj = context.lookup(lookupTCF);
                     String str = obj.getClass().getName();
                     System.out.println(str);
                     factory = (ConnectionFactory) context
                           .lookup(lookupTCF);
[/code]
