  +--org.tp23.jasper.runtime.ObjectPageContextImpl

All Implemented Interfaces:

ObjectPageContext

public class ObjectPageContextImpl

extends java.lang.Object

implements ObjectPageContext

Implementation similar to the PageContext class from the JSP spec. It was written by the authors mentioned and then butchered by Paul Hinds to use it for a different purpose ;)
Basically it is a set of three differnt properties in order of preference...

page

session

application
