public class ContextLoader

extends java.net.URLClassLoader

ClassLoader for HttpContext. Specializes URLClassLoader with some utility and file mapping methods. This loader defaults to the 2.3 servlet spec behaviour where non system classes are loaded from the classpath in preference to the parent loader. Java2 compliant loading, where the parent loader always has priority, can be selected with the setJava2Complient method.
