Running an external app packed inside a jar

Question

Hi!
I'm using these code that I found for executing an external application:
Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("//home//guest//myNativeApp");
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
System.out.println("[INFO] Output of Runtime.exec() is:");
while ((line = br.readLine()) != null) {
System.out.println(line);
Now I'm trying to include "myNativeApp" inside the jar. So when I "call java -jar packedApp.jar" and
the external application should be executed. I know we can use this.getClass().getResourceAsStream("/myNativeApp") to have the path inside the jar file but
I couldn't spawn it. Any ideas? Thanks in advance.

Thank you for reply. I already checked that page. Actually I did not handle the errors in the example to keep the idea simple. I want to put my app inside the jar because later I will use its output and I need to distribute the jar with all the resources inside included the app. I know I will lost all my portability but is an specific need. Do you have a clue?
