All Implemented Interfaces:

ClassResolver

public class JarClassResolver
extends java.security.SecureClassLoader
implements ClassResolver

A simple ClassLoader implementation that loads classes from a set of JAR files. It provides a close() function that forces all currently opened JAR files to be closed (that solves a problem on Windows machines were a opened file cannot be deleted during hot undeploy).
Note: Always prefer to use getResourceAsStream() instead of getResource() as the latter function performs caching (therefore, prevents cached files to be deleted on Windows during hot undeploy).
