Re: EJB Injection

    Hi,

If your EJB have two interfaces (local and remote) then the mappedName 
is applying to both...
Then, I think that it tries to inject the remote interface into the 
servlet which is failing.

Why do you need to specify a JNDI name ?

You can use @EJB on the client side too when running the client in the 
client container.
It will then inject remote proxy on the client side and the local proxy 
in the web side.

Regards,

Florent
