Hi all,
I am having a problem here.I have a set of AgentID and Password which is
stored in a database.
I don't want more than one person to login to my system with the same ID and
Password.
How do I achieve this??
In the init() method of my servlet I create a vector object.Whenever the
Agent logs in I check in the vector whether that agent id is there or not.
If it is not there then I put the Id into the vector ELSE I give a message
Agent already logged in.
When the agent logs off from my system I invalidate the session and remove
the AgentID from the vector.
This works fine if he uses the logoff option of my system BUT when the user
closes his browser the AgentID still remains in the vector and if he logs in
again it says "Agent already logged in" though he is not.
How do I handle this event(closing of browser)???
I want to remove the Agent Id from the vector when the user closes his
browser.
Also when the user closes his browser the session is destroyed on the client
side but it still exists on the server.
So I am unable to determine whether the user has closed the browser or not.
Please enlighten me !!!!
