Setting Base directory

I'm having trouble getting my tomcat base directory set. I'm thinking it's a path issue but not sure.
I can't get my servlet to read a text file in my tomcat directory. I've moved it every where I can think of to get it to read but it's not finding it.

So I did a test and put a line of code in my servlet;

File dir = new File ("exam" + File.separator + "files");
dir.mkdir ();

It puts the new dir in Window/System32.
How do I get it to put it in my tomcat dir?

You should never make any assumptions about what the working folder for a web app is. And you cannot set it.

So when dealing with files from a web app you need to specify an absolute file path.

You can obtain the absolute folder paths for resources within a web app using the ServletContext.getRealPath() method, assuming that your app isn't runnig out of an unexpanded war file.

I guess what I'm asking is this:
I can make my servlet work when I specify file name "C:\\My Document\\file.txt"

But when I move it up to my host provider in my webapps folder, how do I specify where to find the file, since it won't be on my machine anymore? Does this need to be done in my web.xml, and if so how?
Thanks
 
It is sorta covered in the JavaRanch Style Guide.
