Reload Tomcat webapp automatically?

Question

Is it possible to configure web.xml to reload a specific tomcat webapp at a particular time automatically. If not, is it possible to do this programatically?

Answer 1

Programatically - an option is to write an Ant script for reload the webapp you want based on the example given on the Tomcat docs

So you'll be left with a command like

ant -Dpassword=secret reload

and put this into a cron tab on your server (if Unix/Linux) or Windows Task Scheduler for windows.

I notice you've tagged your question garbage-collection . If you are redeploying the web app due to excessive GC, then its better to tackle the root cause of the issue since this reload is only a workaround.

Run a profiler to identify memory leaks.
