tomcat-path and want to open a folder. But that doesn't work. I can't
access these folder or also a file, that is my problem. Can you help me?

You just want some functionality in a class. Where you use it is not
immediately important. Just use it in a servlet. If you don't know how to
use servlets, that is a separate problem. Check out Hunter and Crawford on
servlets.

I can tell you, but I think you will misunderstand. File certainFolder =
new File("[folder file url]"); You need to read a Java book on
files. There are lots of good ones. You can actually just read the
interface, JavaDocs, for File and pretty much get the answer. Most Java
books include something on files. Go to www.java.sun.com and read a
tutorial. Then you can "traverse" away. The answers are all in the File
class, if you know Java sufficiently to be able to read a JavaDoc.

There is no guarantee that there is such a thing as a folder for your
webapps -- it's entirely legal for servlet containers to run your app
directly from a WAR file.
For maximum portability, you should use the
ServletContext.getResourcePaths() method to give you the names of the
resources in a particular "directory" of your webapp -- this will work
whether or not the container actually runs your app from an unpacked
directory.
