JMS11Support in Mule2.0 not comaptible with that in Mule 1.4.x

JMS11Support in Mule1.4 accepts jndiDestinations parameter and if this is set to true, it does a look up of queue/topic in JNDI tree. How can we achieve this similar functionality in Mule 2.0 in JMS11Support? If not, Is there any other way where we can look up queue/topic in JNDI Tree, since current version doesn't accept jndiDestinations or forceJndiDestinations.
