no. (unless the spec says so)

If this is not supported in Tomcat, is there a way or a plan to have
this kind of service? This would really be a big help to many developers.
Just a thought

I think the Cocoon project has such a facility. I'm not sure how complicated it would be to pull out that functionality, but their work might be worth looking at for this.

With all the questions and suggestions flying around, a question to the other programmers: If one was to write a class for the purpose of running classes at set times, what pitfalls would one need to watch
for?
I have a class that loads on startup and runs a continuous loop that is timed (sleeps, wakes up, does something, sleeps again). It runs fine, but I know that it could be better.
Any guidance or suggestions would be appreciated. And maybe we could create an add-on and post it for use in apps that need such a device.
Thanks

Hello,
I am developing a Java web application, and one of the requirements is to run a particular servlet periodically, or even at specified times. Resin provides this ability via its "run-at" configuration element for servlets in web.xml
Example Resin configuration: <servlet> <servlet-name>download</servlet-name> <servlet-class>DownloadNewsServlet</servlet-class> <run-at period='360m'/> </servlet>
However, I haven't found an equivalent configuration for Tomcat. I searched the web and was unsuccessful. So, any pointers as to how I
could achieve this for Tomcat would be appreciated.
There is none and shouldn't be any. I understand the need to run periodical tasks, but J2EE specification, prior to 1.4 has no such provisions. Further, Servlet/JSP specification has no such provision,
even in J2EE 1.4. You'd be best advised to setup a cron-job to perform this periodic activity. There are several good HTTP client packages out there, Jakarta-Commons HTTPclient, to name one, that will help you in building the client side of your cron-job.
Nix.
