public class DynamicClassLoader
extends java.lang.ClassLoader

A classloader whose classpath can be set dynamically.

Version 1.2 adds resource support capability, but for the findResources() which is not implemented.

By default, the classLoader attempts to use the parent class loader, if any, to find a class. By setting the forceDynamicLoading property, the classLoader will always find classes by using the embedded DynamicClassFileFinder.
