Update JSP/HTML page when DB insert/update/delete occur

Hi,

I have a website developed using java/servlets. This site gets input from user.

And, now when an administrator logs in, I want to get the live user names printed on admin page when a new user gets added.

Typically, I would like to update the content of my HTML/JSP page without refreshing when a DB INSERT/UPDATE/DELETE occurs.

Can anyone help me to achieve this using Java/Servlets? if not please provide me an alternate solution.

Thanks

Hi,

The above references gives me to get the data using AJAX. But, what I am looking for is that my page needs to be updated with the latest added users while the administrator is logged in and is in any of the page with admin rights.

Will be having a <DIV> to display the details of the newly added users.

I want this DIV to be updated whenever a new user is added or existing user update his details WITHOUT SENDING REQUEST TO SERVER explicitly.

Thanks.

Hi Tomas,

You mentioned to retrieve we need to send a request to server, I agree with you but my requirement is some thing similar to a page that refreshes automatically when an update to a value is done.

Something similar to a live cricket score update or a stock exchange webpage update where the latest will be updated without sending any request explicitly but the particular div/section  will be updated automatically,

Hope this gives u more idea on the requirement

Thanks
Hi!

Using AJAX you can update only a part of a page e.g. div section where the page or event in the page sends request to the server and updates only the desired section of the page. For the end user is looks like the page is updated without him/her actually hitting a button/link/ page reload.
