Hello Guys, What ever ankit telling is correct, But i want to know, (To Ankit) why you are suggesting comma separated values in field?? Isn't it appropriate to use another table which has "Page Name" (or Page Id) and corrspondign user id? So it will be very simple to handle and most importantly easy to modify????
To Dipesh, If your pages are dynamic, i mean you are changing contents of it using some forms (like Forum and forum notification) then it is easy to do. But if you are replacing static pages (or dynamic pages) and still you want to notify user, then i think you should replace your page using specialized (self developed) servlet form (you have to make one form for uploading your static file or dynamic files). Or you can make a service which checks you page's last modified date on regular intervals and based on that you send emails to all the users. Please don't hesitate to ask if you have some confusion Regards, Nachiket On Thu, Jan 22, 2009 at 4:00 PM, Ankit Garg <ankit.niit...@gmail.com> wrote: > > Well I don't think this should be a big problem.
