org.eclipse.jetty.webapp.WebAppClassLoader
- Direct Known Subclasses:
- OSGiWebappClassLoader
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 behavior 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 and influenced with WebAppContext.isServerClass(String)
and
WebAppContext.isSystemClass(String)
.
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.
