public class JarURLConnection
extends java.net.JarURLConnection

Jar protocol connection class. The class extends the JDK provided JarURLConnection factory. However Jar protocol can not understand the teiid specific protocols like mmfile, mmrofile etc. The issue is if you can register application specific protocols during start-up using system properties the bulit in JAR protocol understands those protocols. However in the Teiid model this need to work by just dropping in in any container. This handler will be called for any class loaders registered with MetaMatrixURLStreamHandlerFactory, so that they understand the application specific protocols.
