- public final class ClassLoaderFactory 
- extends java.lang.Object
Utility class for building class loaders for Catalina.  The factory
 method requires the following parameters in order to build a new class
 loader (with suitable defaults in all cases):
 
 - A set of directories containing unpacked classes (and resources)
     that should be included in the class loader's
     repositories.
- A set of directories containing classes and resources in JAR files.
     Each readable JAR file discovered in these directories will be
     added to the class loader's repositories.
- ClassLoaderinstance that should become the parent of
     the new class loader.
