Examples of org.apache.catalina.loader.WebappLoader

org.apache.catalina.loader.WebappLoader
Classloader implementation which is specialized for handling web applications in the most efficient way, while being Catalina aware (all accesses to resources are made through {@link org.apache.catalina.WebResourceRoot}). This class loader supports detection of modified Java classes, which can be used to implement auto-reload support.
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. @author Craig R.
