Organizing and Adding Tag Library Descriptors

The Workshop group of products scan the tag libraries declared in the web.xml, the standard JSP and HTML tags, and any custom tags. During page development The IDE provides a Design Palette view which works like a tool palette and allows you to drag and drop tags into the page. To create and update tag library descriptors, The IDE includes a specialized TLD Form editor which organizes current tags and attributes into a form layout and provides wizards to define new TLDs.
