public class ClassicMenuItemTag
extends javax.servlet.jsp.tagext.BodyTagSupport

This class is a custom action for conditionally inserting HTML links in a navigation menu.

If the action is used in a page requested with a URL corresponding to the page attribute, only the HTML text is included. Otherwise an HTML link (<a>...</a>) element is used to enclose the HTML text. The action also "URL rewrites" the page URL (embeds a session ID, if needed).
