CGI,
2 5025In 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..
javax.naming.NoInitialContextException: Cannot instantiate
class: org.jnp.interfaces.NamingContextFactory [Root
exception is java.lang.ClassNotFoundException:

(InitialContext.java:247)

at javax.naming.InitialContext.
how can we decide a session bean as stateless or stateful without seeing jar file? i.e. by seeing the class file.
