think you may have to modify the source to achieve what you want here.
Is the initial context used for destination lookup parametrised?
I wonder if a solution would be to have the provider url contain the context
in its path.
so something like: tcp://localhost:61616/dynamicQueues
such that the returned initial context is the "dynamicQueue" context. Then
lookup for any queue would succeed.
Again, this would require some code change to
org.apache.activemq.jndi.ActiveMQInitialContextFactory, and the same context
would not contain a factory reference. But the factory could be statically
configured I guess.
The problem with not having a separate dynamic context for queues and topics
is that they cannot be differentiated.
All patches/contributions welcome with thanks :-)
