I’m trying to open a JAR as a stream, but can’t understand where to get this stream…

JarInputStream s = new JarInputStream(/* what is here? */);

Where to get this stream? I’m trying to open the JAR which is currently is in charge.

From my answer to a similar question:

CodeSource src = MyClass.class.getProtectionDomain().getCodeSource();
if (src != null) {
  URL jar = src.getLocation();
  ZipInputStream zip = new ZipInputStream(jar.openStream());
  /* Now examine the ZIP file entries to find those you care about. */
  ...
} 
else {
  /* Fail... */
}
