One scenario that comes to mind is to load a servlet when the Servlet Container comes
up which;
1. Uses a Timer class (thread with a callback) to signal 5 minute expirations
2. Check an application level array of Interested Client IP Addresses (stored in
ServletContext)
3. For Each Subscribed Client push the DB results as an ObjectStream to a Socket
in a Client Side Applet.
4. Subcribed means a Client page with a Client Side Socket enabled applet was
requested by the Client, the Applet invokes the Servlet to signal its ready for results
This would be fun to code.....I'm not an expert on Firewalls but maybe someone else
can enlighten.
