Hi Raj,
As Ashok mentions, it is recommended to create JMS topics and queues from the realm JNDI tab. This will create both the JNDI destination and the associated queue or channel (with the correct settings).
If you have already created the channel, you can go to the JNDI tab and add the appropriate JNDI entry (which will attach to the channel you previously created), but I would recommend deleting the channel and then recreating it from the JNDI tab. This will make sure it has all the correct settings for JMS use.
