Subject Re: JNDI with ActiveMQ embedded in JBoss AS
Date Wed, 26 Aug 2009 10:00:55 GMT
This all makes sense, the appserver makes RAR objects available in the
application servers moduile private "java:" JNDI context but there is no
logic to register activmq destinations and factories directly in the global
jndi tree.

It is possible to use the activemq initail context to resolve activemq
I guess you have read:

The key is to use a different initial context for clients outside the
appserver, a different value for the jndi system property:


and an appropriate brokerUrl in:

Note that the JNDI name used for the client lookup will be different, it
will not use a "java:" prefix for example and will need to match the naming
convention of the activemq initialcontext.
