JSP files are application components coded to the Sun Microsystems JSP Specification. JSP files enable the separation of the Hypertext Markup Language (HTML) code from the business logic in Web pages so that HTML programmers and Java programmers can more easily collaborate in creating and maintaining pages.
The IBM extensions to the JSP Specification include JSP tags that resemble HTML tags. These JSP tags make it easy for HTML authors to add the power of Java technology to Web pages, without being experts in Java programming.
JSP files support a division of roles...
HTML authors Develop JSP files that access databases and reusable Java components, such as servlets and beans.
Java programmers Create the reusable Java components and provide the HTML authors with the component names and attributes.
Database administrators Provide the HTML authors with the name of the database access and table information.
