All Implemented Interfaces:

public class ContextTag
extends javax.servlet.jsp.tagext.TagSupport

This Tag is used to specify a menu context directly in the JSP-Page. The application has exactly one menu context per user session. This specifies which menu option is currently active. This is done by defining the current menu context path. The menu context can, with this tag, be directly specified in a JSP-Page, or it is set, in the application, before the call to the JSP-Page with the method MenuContext.setPath(java.lang.String).
