It makes no diff whether the lookup is for local or remote beans. What you
need to do is to have an ejb-ref in the dd for the ejb that does the lookup
(and a corresponding comp->JNDI mapping element in your container's dd). I'm
attaching a slide I've made that illustrated this. (Even if attachments on
mailing lists is a no-no). -Of course if you do a lookup from outside the
container, you'll have to use plain JNDI. -But shouldn't apps that look up
EJBs outside a container be J2EE clients and use application-client.xml and
any additional container dds (like weblogic-appclient.xml)?
Anybody agree with my proposal of adding getHomeJNDI()/getLocalHomeJNDI() ?
