# Document Scope and Audience

The JSP 2.0 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 described in the JSP 2.0 Specification.

This document is a resource for software developers who want to create and use custom tags in JavaServer Pages (JSPs). It is also a resource for Web authors who want to use custom tags in JSPs.

This document does not address production phase administration, monitoring, or performance tuning topics. For links to WebLogic Server documentation and resources for these topics, see Related Documentation.

It is assumed that the reader is familiar with J2EE and JSP concepts.
