My program has the following path in the .jar file
src/test/Program.class

and my program is as follow...

Program.java

package test;
import java.io.File;
import java.io.IOException;
import javax.swing.JEditorPane;
import javax.swing.JFrame;

public class Program {

    JEditorPane editorPane;
        public Program() {
        File file = new File("temp.htm");
        try {
            file.createNewFile();
            editorPane = new JEditorPane();
            editorPane.setPage(Program.class.getResource("temp.htm"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public JEditorPane getEditorPane(){
        return editorPane;
    }
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);
        frame.setVisible(true);
        Program p = new Program();
        frame.getContentPane().add(p.getEditorPane());
    }
}

The problem is that I have compiled the program in a .jar file.
The file.createNewFile(); creates the temp.htm file outside the .jar file
So when editorPane.setPage(Program.class.getResource("temp.htm")); is called the file is not found as it searches for file inside the test package.
How to setPage() the temp.htm file whiich is outside the .jar file but in the same folder as the .jar file?
As the temp.htm is a localfile and I want a relative path instead of an absolute path.

Thanks.
