Package org.apache.catalina.manager

Class JspHelper

java.lang.Object
org.apache.catalina.manager.JspHelper
public class JspHelper extends Object
Helper JavaBean for JSPs, because JSTL 1.1/EL 2.0 is too dumb to do what I need (call methods with parameters), or I am too dumb to use it correctly. :)
