VirtualWebappLoader

public class VirtualWebappLoader extends WebappLoader
Simple webapp classloader that allows a customized classpath to be added through configuration in context xml. Any additional classpath entry will be added to the default webapp classpath, making easy to emulate a standard webapp without the need for assembly all the webapp dependencies as jars in WEB-INF/lib. <Context docBase="\webapps\mydocbase"> <Loader className="org.apache.catalina.loader.VirtualWebappLoader" virtualClasspath="\dir\classes;\somedir\somejar.jar"/> </Context> This is not meant to be used for production. Its meant to ease development with IDE's without the need for fully republishing jars in WEB-INF/lib
