configuring EJB access from Servlet

[mcacker]

not sure if this is the right forum, but got a problem figuring out how to access EJBs from a servlet. i have a web app deployed within an ear (i think), but the servlet gets NameNotFoundException. actually i never see the name bound in the console so perhaps my ear is not deployed correctly. it all worked within 2.4.4, but having problems getting it to work in 3. is there anything i have to do to get the ear to deploy other than provide an application.xml for the ear and ejb-jar.xml for the ejbs?

thanks, Mitchell

It worked on 2.4.4 but doesn't on 3

You won't get many answers with vague information. :-(

How are you referencing the ejb?
ejb-link?
direct lookup into global jndi?

Have you used the JNDIView service on the JMX console
to verify the ejb is bound correctly?
Or used the Enumeration available on the initial
context to see what is bound?

Show your deployment descriptors if you have a deployment
problem.

Finally, if I remember correctly, 2.4 had a bug
where it interrupted <ejb-link> in web.xml as the
<jndi-name> when it should be the <ejb-name>

Regards,
Adrian

i looked in JNDIView, but did not see anything there. this being the case i suspect that the ejbs are not getting deployed correctly. see below for (part of) my configuration. thanks, Mitchell
