Classic custom tag

Almost every developer has his own library of methods. And I wonder that few use their own tags on JSP page called custom tags. Any custom tag developer can reuse like any other method.
In the first part of my article I’d like to describe Classic Custom tags.
When you create Classic Custom tag than your class may implement one of three interfaces: Tag, IterationTag, and BodyTag or extends one of two classes TagSupport or BodyTagSupport. I advise you to use classes because in this case you should not implement all methods from interfaces.
