Class JspServletWrapper

java.lang.Object
  extended by org.apache.jasper.servlet.JspServletWrapper

public class JspServletWrapper
extends Object

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.
