managing sessions in rmi application

Question

I'm writing an RMI application which uses swings on the client side. The user has to first login with his email and password. After his login a new JFrame is opened and based upon his email id from first ui, I should fetch data from database in the second ui.

I am new to this thing and I want to know how I can maintain sessions so that username is propagated to all JFrames. I read an article about using system properties as shown to store username:

System.setProperty("application.userName", myUserName);

I want to know whether using system properties to store email is good practice or can i maintain session in a more better way?

Answer 1

Have the login method return a new remote object that is dedicated to that session. In fact it is that session. When the client releases the stub the session will be DGC'd, or you could provide a logout() method in the session object along with all the other methods your session needs.
