I'm a little confused. Are you talking about stateless session beans here?
I'll assume you are using a jboss 3 version and know about the jboss mbean
service lifecycle.
I think what you want to do is create a mbean for each stateless session
bean you wish to have access to and include a depends element in the mbean
configuration with the (generated) object name of the container for the
ejb. The jboss dependency management will assure that your mbean is
started only after the ejb is started. I think (but have not tried) that
you can then use the ObjectName of the container to directly invoke ejb
methods without needing to get a local interface. You will have to make
sure you are sending the correct invocation object, just like say the JRMP
invoker does.
I'm not sure how generic you can or would want to make such an mbean. In
any case you'd configure it and deploy it in an *-service.xml file
