org.apache.struts2.portlet.PortletApplicationMap
The JSP engine (a.k.a Jasper).
The servlet container is responsible for providing a URLClassLoader for the web application context Jasper is being used in. Jasper will try get the Tomcat ServletContext attribute for its ServletContext class loader, if that fails, it uses the parent class loader. In either case, it must be a URLClassLoader. @author Anil K. Vijendran @author Harish Prabandham @author Remy Maucherat @author Kin-man Chung @author Glenn Nielsen @author Tim Fennell
