Only one JNDI server is used by my application at the following (default) place :
"//localhost : 1099".
So, what I don't understand is why my session bean can't retrieve a reference to an
object which is outside the
container (unlike other EJBs or database ressources ...). Is there a particular reason
specific to jBoss for this
?? Or have I made an error using JNDI ?
Note that in the other sense, the connection of my clients to the EJBs on the server
via JNDI, there is no
problem ...
