Java server pages
JavaServer Pages help a user create Web content that has static and dynamic components. On a JSP page, static data is expressed with HTML, XML, or other text based formats, and dynamic content is expressed with JSP element. JSP uses a unified expression language to help integrate it with JavaServer Faces and other J2EE Web tier technologies. JSP also makes use of the JSP Standard Tag Library. In this section, we offer news, research and tutorials on using JSF to help develop dynamic Web content. Learn how JSP can help create platform-independent Web applications using Java EE 5 technology, including JavaServer Faces and the JavaServer Page Standard Tag Library.
