I am using JBoss application server (Jboss 3) and running a JSP + EJB application on that. In my application, after a new user registers, an email should be sent to the user with the password. I used Java Mail API and tried to send that email through JAMES SMTP.
This works fine for the first time, but from second instance onwards, I'm getting the following error:
java.lang.SecurityException: Access to default session denied
And if I restart JBoss server, it once agains works fine -but only the first time.
