Re: Displying Alert
Remember that JSP's are server side processed and then sent to the browser. Using the web browser as your UI delivery framework does limit how much access you have to the servers. "Normally" once the HTML is sent to the browser all contact with the server is broken until the next request from the browser. What you asking for is an "active listener" that will always maintain an open connection to the server. Not sure the web is the best way to set this kind of architecture up given how web apps are "normally" architected. -Original Message- From: Balkrishna R.Parab [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 18, 2001 10:22 AM To: [EMAIL PROTECTED] Subject: Displying Alert Hello Everybody I am working on a project which requred to display alert to the user when ever particular table in database without refreshing that page. 1.

Re: Displying Alert
Best approach would be to create an applet embedded in a JSP that implements a listener for a custom event that is fired from a stored procedure / trigger within the database. other JSP "refresh" approaches may cause too many roundtrips back and forth to the server. -Original Message- From: A mailing list about Java Server Pages specification and reference [mailto:[EMAIL PROTECTED]]On Behalf Of Balkrishna R.Parab Sent: Wednesday, April 18, 2001 10:22 AM To: [EMAIL PROTECTED] Subject: Displying Alert Hello Everybody I am working on a project which requred to display alert to the user when ever particular table in database without refreshing that page. 1.

Re: Displying Alert
Displaying alert by refreshing the pasge is one of the simplest way and i
guess its best possible way. But we need to display alert in all possible
situatation, browser minimize is also included.
I guess I need to write seprate application and that will keep on monitoring
the database updatation. Like MSN or Yahoo messanger ?
Thankx for respaonse
Have a nice day

Subject:Re: [JSP-INTEREST] Displying Alert
what about refreshing the page ( JSP - that gets the information
from your
Database ) every couple of minutes/seconds ?
This can be done with a simple HTTP Response Header:
Something like : HttpServletResponse.setHeader("Refresh", "5;
URL=http://host/path")
