Getting the base location of a project

Aug 31st, 2008

It is quite hard to explain what I mean here, but...

Say I have a class that is stored on a hard drive like this..

Help with Code Tags

Java Syntax (Toggle Plain Text)

project/helpers/MyToolkit.class

i.e. the class MyToolKit is stored in the package project.helpers and would declare it in its code like this..

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
package project.helpers;
 
public class MyToolkit {
 // .... Code etc here.
}
package project.helpers;

public class MyToolkit {
 // .... Code etc here.
}

Say for instance this is stored on the hard drive in the location "C:\MyJavaProjects\MyNewProject\project\helpers\MyToolkit.class" i.e. the base location of the project would be "C:\MyJavaProjects\MyNewProject", where I would like to store things the program can use such as images or configuration files or whatever else.

What I want to know is, from the code of MyToolkit.class i.e. MyToolkit.java... how to find out the base location of the project. I'm aware this could really be done by jumping back 2 directories, since I know MyToolkit is in the package project.helpers, but this is just hard coding from what I already know. I am looking for a method of doing it so that no matter what package, and how many sub-packages MyToolkit could find itself in, how the base location of the whole project can be retrieved. so in the above example I would like a method inside MyToolkit class that can simply work out where the base location is on the actual hard drive, so that method would return the string "C:\MyJavaProjects\MyNewProject".

In the end I just want to keep my program and resources seperate, and therefore need a way of find my way back to the root.

Its been really hard to try to explain it, sorry if it isn't clear.

EDIT:

When the whole thing is done, I intend to jar the whole program up and what I really need is the full path name of the directory the .jar is stored. Can anyone suggest a way of doing this?

Cheers.
