ScopedURLClassLoader	A URLClassLoader that is tight to some J2EE deployment and that is able to share classes/resources under the associated scope.

Package org.jboss.deployment.scope Description

Introduction

This package hosts an extension to the J2eeDeployer that is able to "virtually" merge J2EE applications in the jboss runtime within a so-called "scope". Scoped applications are able to share classes and resources which allows to remove redundancies from your ears/jars (management impact) and introduces additional runtime optimisations (performance impact).

The Global Scope Deployer

We provide a default "global scope" deployer that merges all applications in a single scope. It comes with an appropriate deployment/undeployment logic that analyses Class-Path annotations in your ears Manifest - Marc: this is not necessary to get the resource sharing effect, but it is useful if deploying mutually dependent ears. The classloading scheme prefers local resources to dispatching to the scope such that you may still have the advantage of including redundant class files.
