How to change working directory in Tomcat

Hi all,

How to change working directory in Tomcat? Currently from my JSP I'm creating file and after that I'm finding this file in TOMCAT_HOME/bin, but I don't want to be there, I would like to be in my ROOT directory!
I know that I have to write something in web.xml or server.xml, but I don't know what exactly?!?!
Is there anybody that knows how to change my working directory?
Please write the lines that I have to add to this xml files in order to change my working directory!
Thanks in advance!

All that I need is to create this file in my Root directory. How to get the root directory and to create the file in this directory?
try this:

String rootdir = getServletConfig().getServletContext().getRealPath("/");

use this directory to create the file

Only getServletContext().getRealPath( "." ) doesn't works...  "getServletConfig()" must be added in front. But what actually retruns this "getServletConfig()" ?!?!
All JSPs are compiled into servlets, and getServletConfig() is a method of HttpServlet :-)

Hope it's all working!

Good luck!
