We're currently thinking about using Javascript from within a JSP frame to refresh itself
The scenario is something like this ,
The DB is updated some process, whenever the DB updates , teh front end screen
(if open ie if it is viewed by soembody) has to be refreshed to get fresh set of data.
The client wanted to do soem kind of pushing rather doing a polling.
If you have done something like this before or read anything
plz share tour ideas or code or any articles worth to get this done

Thnaks very much in advance
