NullPointer exceptions are insanely common, you might want to be a tad more specific. Also consult glassfish tutorials for getting started with glassfish.

particularly, give the exact copy/pasted code (or a snippet), and the exact output, and

use the CODE tags

Finally i found solution for this problem



@EJB
RemoteInt remote = null; It's creating problem because it's assigned to null;
p s v m(){
remote.display();
}

i changed to above code to
@EJB
[B]RemoteInt remote;

It's working now.

but can any one give explanation on this.
