Class JspServlet

  • All Implemented Interfaces:
    Serializable, Servlet, ServletConfig, PeriodicEventListener

    public class JspServlet
    extends HttpServlet
    implements PeriodicEventListener
    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.
