[jboss-user] [JNDI and Naming] - JNDI lookup from JBoss embedded MQ Provider

i have successfully embedded ActiveMQ via JCA/RA in JBoss 5.1:

Now I like to use JNDI to lookup ActiveMQs ConnectionFactory and the Destinations from a java/jms client outside the application server.

My Problem is, that i get a null pointer object back form jndi lookup, and this is obviously not new:

In this thread some JBoss guy writes about this architecture problem:
JBoss answer 
"/The connection factories provided by a Resource Adapter (RA) are 
typically not available for use by clients that are outside of the 
application server. That is, the JCA specification is intended to 
provided resources to the application server, and relies upon behavior 
on the part of the application server in connection pool management, 
transaction management, and security. 

Also, for this reason, the JNDI location of the RA's ConnectionFactories 
should be located in the "java:" namespace. This namespace is local to 
the jvm and has no visibility to external clients./" 

So my question is, may I use MQ Providers from Clients outside the application server or may i only use it via EJB components like MDBs ?

I am confused - because JBoss Messaging is (as far as i know) also embedded via JCA and also bound to global JNDI and - I can successfully lookup the JBoss Messaging ConnectionFactory from a client outside !!! Why does it work - is this bug a feature ? ;-)

Thx so far !
