public class BaseClassLoader
extends java.security.SecureClassLoader

This class overrides the SecureClassLoader class. It allows bypassing the delegation model, by which child classloaders are supposed to resolve classes by first delegating the lookup to their parent classloader.

Inheriting classes should override this class' findClass(String) method to support looking up classes from different sources. Accordingly, inherinting classes should also override this class' resource-related methods, such as findResource().
