tomcat and java cache
I have a pretty big website that uses java cache from which it retrieves the html. So I have a scheduled job(servlet) that get's some data from a server and stores it in a java cache(Oscache or Ehcache for those who know it). My problem is next: whenever the server (tomcat) is restarted, the cache is emptyed and should be "populated" when the server is back on.So long story short...is there any way to run a servlet whenever tomcat starts? so when tomcat starts, a servlet should be run. I don't know if that's possible but can someone tell me if it is and how it should be done?

Implement a ServletContextListener, it has two methods, one of each of
which fire respectively when the Context is started and when it is
terminated.
You can place your cache populating code in the startup method.

Now Tomcat is also a cool application server
---------------------------------------------------------------------------
in theory load-on-startup
<servlet>
<servlet-name>YourSelvelet</servlet-name>
<servlet-class>blah.blah</servlet-class>
<load-on-startup> 1 </load-on-startup>
</servlet>
and then in the servlet itself the INIT section will run so you can do your
thing there.
Dont know this OSCache tool... but you must be caching like crazy if letting
the first request set it up is going to take too long.... have fun
