public class CarbonWebappClassLoader
extends org.apache.catalina.loader.WebappClassLoader

Customized WebappClassloader for Carbon. This class introduces a new classloading pattern which is based on the webapp-classloading.xml file. The default behaviour is specified in the container level configuration file. But webapps has the ability to override that behaviour by adding the customised webapp-classloading.xml file into the webapp.
