Get absolute path to File

Question

So I'm trying to use BufferedImages necause their eaier for and it seems loading them is a bit more finiky. I think you need the absolute path to load them and I have tried just doing src/Package.image.png but when I export to runnable jar it doesn't work. This code works inside eclipse but for some reason it doesn't work when I export it as a .jar .

package MainGame;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;

 public class GraphicsPath {





public static String getGraphicsPath(){


    String path = null;

    PrintWriter writer = null;
    try {
        writer = new PrintWriter("text.txt");
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    path = GraphicsPath.class.getProtectionDomain().getCodeSource().getLocation().getPath();  


    System.out.println(path);

    writer.println("orignal path    " + path);

    //FOR LINUX
    String[] splited = path.split("/");


    //FOR WINDOWS
    //String[] splited = path.split("\");
    writer.println(path);


    path = path.replace("%20", " ");

    path += "MainGame/";

    writer.println(path);
    writer.close();

    System.out.println(path);
    return path;

}

}

Here is the contents of text.txt when its exported to the jar

orignal path    ./
./
./MainGame/

Here is the contents of text.txt while still in the java project

orignal path    /home/mini/workspace/Pokemon%20Game/bin/
/home/mini/workspace/Pokemon%20Game/bin/
/home/mini/workspace/Pokemon Game/bin/MainGame/

If I understand you correctly, you have a package.image.png file that you need to read, it is inside the .jar file.

I have had this problem before, and I think you cannot use path to locate this file. In one of my projects I actually used a URL to specify the location of the file. I'll give you an example of what I did

so In my jar file, there is a images folder. say i have /images/x.png

I do this

URL u = this.getClass().getResource( "/images/x.png" );
a=ImageIcon(u);

I used this to create imageIcon, but I think you can check how to read a file with URL.

EDIT: I just tried this to read a file, it works.

URL test =Class.class.getResource( "/docs/test.txt" );
BufferedReader in = new BufferedReader(new InputStreamReader(test.openStream()));

So you can wrap the InputStreamReader with other stuff to get the image
