org.mortbay.jetty.webapp.WebAppClassLoader
public class WebAppClassLoader
- 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
WebAppContext.setParentLoaderPriority(boolean)
method.
If no parent class loader is provided, then the current thread context classloader will
be used. If that is null then the classloader that loaded this class is used as the parent.
