Document Scope and Audience
The JSP 2.1 specification enables you to create and use custom tags in Java Server Pages (JSPs). Custom tags are an excellent way to abstract the complexity of business logic from the presentation of Web pages in a way that is easy for the Web author to use and control. You can use custom JSP tag extensions in JSP pages to generate dynamic content, and you can use a variety of Web development tools to create the presentation.
WebLogic Server fully supports the tag extension mechanism.
