when I put the javamail example code (/javax/demos/msgsend.java) in my own server code for the Corba Client Application.

Intrestingly, the program runs successfully when it's a stand alone.

I tried calling msgsend constructor from my own application so that as soon as the initialization occurs the email is sent. I tried other alternatives too, but it seems that
this program runs only when it's running standalone.
