NameNotFoundException on lookup

Question

I see a bunch of questions in this area, but not a solution.
I have an applet that tries to instantiate a stateless session bean to talk back
to the server.
I have an ear deployment that contains a bean (jar) & a application (war). The
bean has a jndi entry (that I can see in the admin console, I can test the ejb
in the admin console as well), but when the applet (that is in the war), does
a lookup, it gets a NameNotFoundException.

I think I am missing a piece.

Answer 1

Yes. it is in the JNDI tree.

Does the bean's JNDI name appears in the server JNDI tree?

I do have a remote and home interface. Can't use an intermediate servlet

Hi,
If you use the EJB from your applet you must make the home and remote
interfaces
avavilable for your applet.
Wouldn't it be easier to use an intermediate servlet.
