Title: Timed Servlet

Jay,

 

I'm not sure why you need it to be a servlet... could it be a stand alone application?  I would just set the thing to be run via a script/cron job, fetch all the pages you should monitor over http, and do a checksum on the page to determine if it has changed... and keep track of everything in a file or database.  My advice is limited because I am not aware of all your constraints.  Let me know why this wont work and I can help you find something that does.

Can anyone help with these questions:

I have a project where I need a servlet to continue to run indefinitely and check for updated pages to an intranet site. It is supposed to send out an email to a department's content shop and notify them if their pages have not been updated in the past 30 days.

question #1: Is this at all feasible?
question #2: What will the strain be on the web server (using websphere 3.5)?
question #3: Will it affect other applications running on the server?
question #4: How can this be implemented? ( Kinda of got an idea of maybe a 'bot' of some type to fetch the header info of certain pages )

Thanks in advance.
