Auto JAR creation.

Question

Hi there,
I am trying to create a JAR file from within a program. This Jar file is intended to contain the client program and required file to be viewed by other users.
I was reading the jar package API (i.e JarStreamIn/Out classes but they seem to rely on an existing Jar file ).
Is there anyway of creating a jar file from the application?
Thank you

thank you
The example you posted guided me towards the solution...
here it is... It seems to be doing what I needed... at least so far...
try{
       this.fos = new FileOutputStream(this.fileName);
       this.jos = new JarOutputStream(fos, new Manifest(new FileInputStream(manifest)));
    }catch(Exception e){
System.out.println("Error: " + e);
    }//end ScoobyJarMaker
    public void doJar(){
          try {
             for (int i = 0; i < this.archiveFiles.length ; i++){
                String fPath = this.archiveFiles;
                    FileInputStream fis = new FileInputStream(fPath);
                    BufferedInputStream bis = new BufferedInputStream(fis);
                    JarEntry fileEntry = new JarEntry(fPath);
                    //JarEntry fileEntry = new JarEntry(fis);
                    jos.putNextEntry(fileEntry);
                    byte[] data = new byte[1024];
                    int byteCount;
                    while ((byteCount = bis.read(data, 0, 1024)) > -1) {
                         jos.write(data, 0, byteCount);
     }//end for
jos.close();
          } catch (IOException e) {
System.out.println("JAR ERROR : " + e);
