????Creating a directory in a different directory??????

[Amit Roy]

hello friends
I am facing a unique problem first of all i am using Tomcat with JSP. What i want to do is accept a folder name from the user and create a folder by that name. I have written a bean for this which goes.

import java.io.* ; 
public class FileManagment
 {
   String directoryname;//this is commin from the textbox
   public void setDirectory(String directoryname){
   this.directoryname = directoryname  ;
   File f1 = new File("/");
   String path = f1.getParent() ;
   File f = new File(path,directoryname); //creating a file instance
   f.mkdirs();
   }
}

my problem is that this code is working fine on my local machine but when i use it on the server it is creating a folder in some unknown place. Suppose i have a folder "A" inside which i am placing my class file.
My questions:
1) Which of the methods will return me the String "root:\A\"
because most of the methods are returning me "root:\A\directoryname" or "directoryname"
where directoryname = the String that i am passing in the file object f (c the code)so that i can pass it in the first argument of f and make a directory in the current directory
2)How do i create a directory in any place i want. Eg suppose i have my class file placed in c:/tomcat/webapps/classes and i want to create the directory in c:/tomcat/webapps/application/upload
Any ideas will be highly appritiated
URGENT
