public class WebappLoader extends LifecycleMBeanBase implements Loader, java.beans.PropertyChangeListener
This class loader is configured by adding the pathnames of directories,
JAR files, and ZIP files with the addRepository() method,
prior to calling start(). When a new class is required,
these repositories will be consulted first to locate the class. If it
is not present, the system class loader will be used instead.

(so that the actual parent will be the system class loader).
|
WebappLoader(java.lang.ClassLoader parent)
Construct a new WebappLoader with the specified class loader
to be defined as the parent of the ClassLoader we ultimately create.
