Copy a world from the jar file

hey, how can i load a world that i have in the jar file?

if a use a inputStream to get a file or location outof my jar it always returns null....

Code:

new File(Main.r.getResource("/maps/" + Target + "/").toString());

Sorry for my bad english....

 

@Badwolf330 Do a simple Google Search about copying files from the jar to a directory. I am positive you will find an answer to this mostly Java related question.

 

@teej107

did search the whole day.... did try many things but nothing works....

Code:

try 
        {
           ArrayList<String> ignore = new ArrayList<String>(Arrays.asList("uid.dat", "session.dat"));
           if(!ignore.contains(source.getName())) 
           {
               if(source.isDirectory()) 
               {
                   if(!target.exists())
                   target.mkdirs();
                   String files[] = source.list();
                   for (String file : files) 
                   {
                       File srcFile = new File(source, file);
                       File destFile = new File(target, file);
                       copyWorld(srcFile, destFile);
                   }
               }
               else 
               {
                   InputStream in = new FileInputStream(source);
                   OutputStream out = new FileOutputStream(target);
                   byte[] buffer = new byte[1024];
                   int length;
                   while ((length = in.read(buffer)) > 0)
                       out.write(buffer, 0, length);
                   in.close();
                   out.close();
               }
           }
       }
        catch (IOException e) 
        {
            System.err.println(e.getMessage());
       }

this works if a send a folder that isn't in the jar... but if a foldor is in the jar i can't use this... i really got no idea how to fix this...

HELP

 

Ignore my fail I got a valid awnser below.

Code:

getClass().getResource("Path here")

This code returns a file . . . of course replace it with the path of the world inside your jar.
I hope this helps.
It works fine for me.

IF this doesn't help im sorry Im tired and wasn't thinking before posting. Very sorry I'll try to find an awnser(That I've loaded a file with).


VERY SORRY

I found this for now. Magical Clickable Blue Text To An Awnser Maybe.
