In my project iam integrating telephone line using some
bridge. To connect my project to that telephone line they
have give some jar file. Using dat i connected with that..
To handle that event like call attented, call disposed and
idle time they have give one event listener class.. I did
every thing and this class is alsoo called when a
particular event is fired. The only thing is i wanna call
EJB from that event listener method.. But the EJB is not
getting initated and exception is thrown. This below shownn
error is occured only i try to call it from this event
listener class. In other places EJB calling is working
fine..

Answer / gowrisankar

when u r calling jar file is i think Ejb Component
when u r wring calient in event listener itself u have to
write correct "jnidi name" specific to that particular
EjbComponent.

it is not suitable u r clling jndi name with ejb component
name this is only one reason

second solution
if posible to catch jar file deploy in weblogic server
and test that ejb jar file component it give component name
and jndi name then use that particulr jndi name

or open jar file check vsddl file itself jndi name
