The JavaServer Pages™ (JSP) specification is built on top of
the Java™ servlet specification and is intended to provide for
better separation of the presentation (e.g., HTML markup)
and business logic (e.g., database operations) parts of web
applications. JSP is supported by all major web and application
servers. A partial listing of JSP-compliant products is
available at Sun Microsystems’ JSP web page:
http://java.sun.com/products/jsp/
A JSP page is a web page that contains both static content,
such as HTML, and JSP elements for generating the parts
that differ with each request, as shown in Figure 1. The
default filename extension for a JSP page is .jsp.
Everything in the page that’s not a JSP element is called template
text. Template text can be in any format, including
HTML, WML, XML, and even plain text. Since HTML is by
far the most common web page language in use today, most
of the descriptions and examples in this text are HTMLbased.
You should be aware, though, that JSP has no dependency
on HTML. Template text is not interpreted at all; it’s
passed straight through to the browser. JSP is therefore wellsuited
to serve any markup language.
When a JSP page request is processed, the static template
text and the dynamic content generated by the JSP elements
are merged, and the result is sent as the response to
the client.
