Class Handler

java.lang.Object

java.net.URLStreamHandler

com.netphantom.common.npjar.Handler

All Implemented Interfaces:

IJarURLStreamHandler

public class Handler
extends URLStreamHandler
implements IJarURLStreamHandler

The NpJar URLStreamHandler.

This class must be named Handler for the default system handler search mechanism to function. Normally you will not use this class directly; NpJarURLStreamHandlerFactory documents how to globally install npjar support. However, you can employ NpJar using just this class:

   Handler npJar = new Handler(...);
   URL url = new URL (..., npJar);
