Register a JNDI name in an MBEAN

[bmargulies]

I want to have an MBEAN create a JNDI name that is visible from a session bean (with appropriate resource-ref, of course).

Is this just a matter of obtaining the initial context and creating an entry, or are there more complex issues?

See the remote/local invocations in the FAQ:

http://www.jboss.org/wiki/Wiki.jsp?page=FAQJBossJMX

If your ejb is collocated with the mbeanserver you can follow the advice in the FAQ (first item), or even try to register to the local jndi a dynamic proxy to the mbean. Haven't tried the second, but I believe it should work.

OK, I'm feeling dumber and dumber. My primary reason for embodying something as an mbean is to bring some JNI into the environment. I don't need 'remote' access at all, I just need an ordinary stateless session bean to get to the object that uses the JNI. I was assuming that I wanted to do this by advertising something via JNDI. So, does that give me any less complex options than the FAQ? Whatever I do also has to work in websphere.

Unfortunately, the websphere end of this is pre-1.2 JMX. Could you possibly point me at an example of something like the dynamic proxy idea?

I'd register to jndi the dynamic proxy returned by

MBeanServerInvocationHandler.newProxyInstance(..);

I'd guess this will work with both servers.
