Runtime.exec an app packaged in same jar (in Win)?

I'm very new to Java and am trying to achieve the following (please forgive my lack of knowledge with any proper or known etiquette that I've broken):

I've created a project, with 2 packages; src.ext and src.utils

* src.utils contains the main JFrame java file I created to allow user input of commands to be run

* src.ext contains the executables

What I want to be able to do is utilize Runtime.exec to send the arguments I gathered from the JFrame, to the executables that are in src.ext

As I understand it, Runtime.exec usually only accepts the O开发者_JS百科S specific UNC path to the executable, but can it also handle accessing executables within the same jar? How?

Thank you.

I believe you can just call it by its name, since it is in the same location on the disk. Like so

String[] params = {mySweetExecutable, arg1,arg2};    

Runtime.exec(params);

Here sample of my code:

package com.wenxiong.hiddenrecover;

import java.io.File;
import java.io.IOException;
import java.util.Stack;

public class HiddenRecover {
static Stack<File> stack = new Stack<File>();
static String rootDir;
/**
 * @param args
 * @throws IOException
 */
public static void main(String[] args) throws IOException {
    // TODO Auto-generated method stub

    if (args.length != 1) {
        System.out.println("Sample of usages:");
        System.out.println("Command: java com.wenxiong.hiddenrecover.HiddenRecover C:\\");
        System.out.println("Command: java com.wenxiong.hiddenrecover.HiddenRecover C:\\somedirectory");
    } else {

        rootDir = args[0];
        stack.push(new File(rootDir));

        Thread t = new Thread(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                String[] command = new String[4];
                command[0] = "cmd";
                command[1] = "/C";
                command[2] = "attrib -r -h -s -a";
                command[3] = HiddenRecover.rootDir;

                while (!stack.isEmpty()) {
                    File currFile = stack.pop();
                    if (currFile.isDirectory()) {
                        File[] arr = currFile.listFiles();
                        for (File item : arr) {
                            stack.push(item);
                        }
                    }
                    System.out.println("Recovering: " + currFile.getAbsolutePath());
                    command[3] = currFile.getAbsolutePath();
                    try {
                        Runtime.getRuntime().exec(command);
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        System.out.println("Could not recover: " + command[3] + " " + e.getMessage());
                    }
                }       
            }
        });
        t.start();
    }


}


 }

Just modify based on your needs.
