	General Approach to Accessing Variables

The general approach of accessing call session variables-either simple or complex- is to add code to a node.

For a Servlet Node, override the following method:

• public void servletImplementation(SCESession mySession)

For an "Other" Node (for example, Form, Menu, Data), override the following method:

• public void requestBegin(SCESession mySession)
