      org.jboss.net.protocol.njar.Handler

public class Handler
extends URLStreamHandler

A protocol handler for the n(ested)jar protocol.

This is class allows you to use the njar: URL protocol. It is very similar to it's jar: cusin. The difference being that jars can be nested.

An example of how to use this class is:


    URL url = new URL("njar:njar:file:c:/test1.zip^/test2.zip^/hello.txt");
    url.openStream();

Please be aware that the njar protocol caches it's jar in temporary storage when connections are opened into them. So for the above example, 2 files would cached a temp files names similar to nested-xxxx.jar
