Restarting webapplication from servlet/jsp?

Hi,

I would appreciate your help concerning the following problem:

I have an application running on Tomcat.
After uploading some xml-files I want to restart the application which uses these xml-files.

Usually I can do that with the Tomcat Manager.
Unfortunately I can�t do that in that case (www.myproject.com sends me to the webapp-director => index.html, I don�t have access to the tomcat root page).

So I need a servlet/jsp that does the following thing:
WebApp mywebapp = Tomcat.getWebApp("mywebapp");
mywebapp.restart();

Or can I transfer the existing tomcat manager somehow into my webapplication?

Or can I write a second application that starts/stop/restarts my webapplication?

Thanks for your advice,
Robert.

Seems to me you don't really need to restart the application, you just need to re-initialize the part that depends on the XML, right?
I have an on-line test engine that uses XML for configuration and for defining the test questions. Naturally I don't want to restart the whole thing (which is likely to have people using it) when one test script is changed.
The solution I used is to have a password protected request that can perform various management functions. One of these functions is to build a new set of tests from the XML files. The new set replaces the old set in a synchronized operation, and existing users keep their own copies of the test they are working on. As the existing users quit, those outdated copies are eventually garbage collected.
