exception accessing ejb from servlet in OCj4

Hi,
I'm aving a problem accessing a stateful session bean from a servlet. I'm using a jndi lookup to do it because I need that a client has its own bean reference...

My code is:



and I have a reference to EJB into web.xml:

<ejb-local-ref>
<ejb-ref-name>ejb/Carrello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home></local-home>
<local>carrello.model.CarrelloLocal</local>
</ejb-local-ref>

If I use @EJB annotation to inject the servlet, it works fine.
Instead using jndi lookup throws a NamingException because it doesn't find java:comp/env/ejb/Carrello entry.

Any idea about the problem?

Valerio,
Pardon me if I am stating the obvious, but first of all, in order to lookup an EJB from a servlet, both the EJB and servlet usually need to be in the same EAR, i.e. same JEE application.
Also, it looks like you are using the EJB's local interface, in which case I believe your lookup string is wrong.
I don't recall the correct format, but I believe it is detailed in the OC4J documentation, which is available from:

http://www.oracle.com/technology

Good Luck,
Avi.
