JSP scripting elements and variables
Standard scripting variables
The following scripting variables are always available:
* out ~V The JSPWriter used to write the data to the response stream.
* page ~V The servlet itself.
* pageContext ~V A PageContext instance that contains data associated with the whole page. A given HTML page may be passed among multiple JSPs.
* request ~V The HTTP request object.
* response ~V The HTTP response object.
* session ~V The HTTP session object that can be used to track information about a user from one request to another.
Scripting elements
There are three basic kinds of scripting elements that allow java code to be inserted directly into the servlet.
* A declaration tag places a variable definition inside the body of the java servlet class. Static data members may be defined as well.
<%! int serverInstanceVariable = 1; %>
* A scriptlet tag places the contained statements inside the _jspService() method of the java servlet class.
<% int localStackBasedVariable = 1; out.println(localStackBasedVariable); %>
* An expression tag places an expression to be evaluated inside the java servlet class. Expressions should not be terminated with a semi-colon.
<%= "expanded inline data " + 1 %>

JSP Actions
Great JSP web hosting can be found at Alden JSP Hosting.
JSP Actions
JSP actions are XML tags that invoke built-in web server functionality. The following actions are provided:
* jsp:include
Similar to a subroutine, the Java servlet temporarily hands the request and response off to the specified JavaServer Page. Control will then return to the current JSP, once the other JSP has finished. Using this, JSP code will be shared between two other JSPs, rather than duplicated.
* jsp:param
Can be used inside a jsp:include, jsp:forward or jsp:params block. Specifies a parameter that will be added to the request's current parameters.
* jsp:forward
Used to hand off the request and response to another JSP or servlet. Control will never return to the current JSP.
* jsp:plugin
Older versions of Netscape Navigator and Internet Explorer used different tags to embed an applet. This action generates the browser specific tag needed to include an applet.
* jsp:fallback
The content to show if the browser does not support applets.
* jsp:getProperty
Gets a property from the specified Java bean.
* jsp:setProperty
Sets a property in the specified Java bean.
* jsp:useBean
Creates or re-uses a Java bean available to the JSP page.

Java Servlets
A Java program that runs as part of a network service, typically an HTTP server and responds to requests from clients. The most common use for a servlet is to extend a web server by generating web content dynamically. For example, a client may need information from a database; a servlet can be written that receives the request, gets and processes the data as needed by the client and then returns the result to the client.
Applets are also written in Java but run inside the JVM of a HTML browser on the client. Servlets and applets allow the server and client to be extended in a modular way by dynamically loading code which communicates with the main program via a standard programming interface.
Servlets are more flexible than CGI scripts and, being written in Java, more portable.
Java Servlet technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server and for accessing existing business systems. A servlet can almost be thought of as an applet that runs on the server side -- without a face. Java servlets have made many Web applications possible.
Servlets are the Java platform technology of choice for extending and enhancing Web servers. Servlets provide a component-based, platform-independent method for building Web-based applications, without the performance limitations of CGI programs. And unlike proprietary server extension mechanisms (such as the Netscape Server API or Apache modules), servlets are server- and platform-independent. This leaves you free to select a "best of breed" strategy for your servers, platforms, and tools.
Servlets have access to the entire family of Java APIs, including the JDBC API to access enterprise databases. Servlets can also access a library of HTTP-specific calls and receive all the benefits of the mature Java language, including portability, performance, reusability, and crash protection.

Java Server Pages (JSP)
(JSP) A freely available specification for extending the Java Servlet API to generate dynamic web pages on a web server. The JSP specification was written by industry leaders as part of the Java development program.
JSP assists developers in creating HTML or XML pages that combine static (fixed) page templates with dynamic content. Separating the user interface from content generation allows page designers to change the page layout without having to rewrite program code. JSP was designed to be simpler than pure servlets or CGI scripting.
JSP uses XML-like tags and scripts written in Java to generate the page content. HTML or XML formatting tags are passed back to the client. Application logic can live on the server, e.g. in JavaBeans.
JSP is a cross-platform alternative to Microsoft's Active Server Pages, which only runs in IIS on Windows NT.
Applications written to the JSP specification can be run on compliant web servers, and web servers such as Apache, Netscape Enterprise Server, and Microsoft IIS that have had Java support added.
