I'm using javamail and weblogic/EJBs. With EJBs I would like to make a connection to the MailServer. The JavaBean is stateless so if I make a connection to the mail server after going back to the servlet I loose all the server related objects. So I created a class which stores the EJB-MailServer sessoin identifiers. This should be a serializable object. That's fine but the session that I got from the mail server is not serializable :-((( So I got the NotSerializableException when I would like to put the javamail session into my serialized object. The problem is that the Session class is final so I can't extend it to be serializable. So the question would be how I can store the MailServer related information (Session) to keep alive the MailServer connection ? Shall I use Entity Beans?? Would it solve the problem?
