Subject refresh JSP webpage when Derby DB is changed
Date Fri, 12 Feb 2010 16:17:22 GMT

The goal is to refresh a JSP web page on a web browser when the Derby DB on
the server is changed.
The rate of database change is 1-10 times per hour.
The record size is about 1000 bytes.
The user use the browser to modify the data and write back to the Derby DB.
The web server is tomcat.
I am thinking of comet programming - pushing data from the server to client
when the Derby DB is changed.
Is that a good idea?
How to do that with javascript or java?
Any sample code or tutorial?
