Java Programming

I have tried to set relative path in Netbeans as

String fileName=getClass().getResource("./resources/folder/abc.xml").toString().substring(6);

This works properly when i run class file but, it does'nt work for jar file, the jar file does'nt run.
It gives an Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException in main method

public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {

            public void run() {
                new MyProject().setVisible(true);     //Exception on this line
            }
        });
    }

I also used this code:

File Currentdir=new File(".");
        try{
           String CurrentWorkingDir=Currentdir.getCanonicalPath();
        } catch(Exception e){System.out.println(e);}

File file =new File(CurrentWorkingDir+"./resources/folder/abc.xml");

but in File it gives the same Exception

if i use getCanonicalPath() in String as:

String fileName=CurrentWorkingDir+./resources/folder/abc.xml"; //CurrentWorkingDir=Currentdir.getCanonicalPath();{code}
it works properly

Is there any way to set relative path so it works in any situation.
