Developing JSP Custom Tags - Project (Continue...)

Introduction

Custom tags are distributed in a tag library, which defines a set of related custom tags and contains the objects that implement the tags. The object that implements a custom tag is called a tag handler.

JSP technology defines two types of tag handlers: simple and classic.: Simple tag handlers can be used only for tags that do not use scripting elements in attribute values or the tag body.; Classic tag handlers must be used if scripting elements are required.
