Hi all,

I have read the docs regarding remote JNDI lookup, but somehow it doesn't seem to match my first-hand experiences. I hope someone can clear this up for me.

My application basically looks like this:

-- service.jar (EJB JAR)
-- web.war

Additionally, there is an remote client talking the app using EJB remoting...

1) Local JNDI lookup (used inside the JAR and partially in the WAR):

JNDI name: java:global/Business/service/FooEJB!foo.bar.ServiceLocal

This works nicely, always.

2) Remote JNDI lookup, from within the WAR:

+InitialContext is basically empty in this scenario.+

JNDI name: ejb:Business/service/FooEJB!foo.bar.Service

This works as well, but there are two strange(?) differences compared to the local lookup:
The prefix must be 'ejb:', 'java:' doesn't work. Also it doesn't work with 'global/' (or any other scope). Ok, I admit, this may be a remote thing, but still I'm wondering...

3) Remote JNDI lookup, from external application:



JNDI name: java:Business/service/FooEJB!foo.bar.Service

Now it's getting crazy. This works as well, but as you see I need to use 'java:' prefix. With 'ejb:' prefix I get the dreaded NameNotFoundException  :( 

Can anyone make any sense of this?!

Thanks in advance!
