public class test{
public static void main(String[] args) throws IOException{
JarOutputStream jout=new JarOutputStream(new FileOutputStream("kiss.jar"));
byte[] data=new byte[1024];
int len=0;
FileInputStream fin=new FileInputStream("test.java");
jout.putNextEntry(new JarEntry("test.java"));
while((len=fin.read(data))!=-1)
jout.write(data);
jout.close();
fin.close();

Manifest mf=new Manifest(new FileInputStream("MANIFEST.MF"));
JarOutputStream jout=new JarOutputStream(new FileOutputStream("kiss.jar"),mf);
