The Servlets trail teaches you about servlets, the bodies of code that run inside servers, and extend their functionality. Topics include: Overview of Servlets, Client Interaction, The Life Cycle of a Servlet, Saving Client State, Servlet Communication, Utilities for Running Servlets, and Running Servlets.

The usefulness of static HTML has run its course and web sites whose sole content is comprised of static HTML pages are now often dismissed as "brochureware." The real world is dynamic and web pages that want to reflect this must be capable of accommodating this dynamism. It is possible, however, to deliver dynamic data content to otherwise static HTML pages by leveraging the power of Java and JavaServer Pages (JSP). This introductory tutorial explains The Definition of a JavaServer Page along with a simple form-based article listing application.

This is a sample chapter from the book 'Professional JSP' by Wrox Press. Inarguably the best book to master Java Server Pages.

This is a short introductory article on JavaServer Pages. It talks about the features of JSP, a simple example, and includes some useful JSP related-links.

Window toolkits typically provide a layout mechanism that positions widgets in a container. For example, AWT and Swing have layout managers, and VisualWorks Smalltalk has wrappers. This article presents a template mechanism for JSP that allows layout to be encapsulated and reused. JSP templates minimize the impact of layout changes and encourage modular design.

JavaServer Pages (JSP) are a great mechanism for delivering dynamic Web-based content. JSP provides a set of predefined tags, but you can also define your own tag extensions that encapsulate common functionality. This article will show how easy it is to build, deploy, and use your own custom JSP tag, using the Servlet/JSP reference implementation, Tomcat.

In this 5-page tutorial, you'll learn how to write, compile, and serve a simple servlet. Also, includes other servlet-related resources.

Written primarily for those currently developing on the server in JavaScript, this article explains the basics of working with Java on the server through Sun's Java Servlet API. It includes a brief overview of servlets and their role in server-side software development, and Comparison of JavaScript applications with servlets in a number of crucial areas of program design.

The author notes "This document explains the concepts of Java Servlets and provides a step-by-step tutorial for writing HTTP Servlets with complete source code for the example Servlets. The tutorial and the other chapters cover all facets of Servlet programming from a simple "Hello World" Servlet to advanced Servlet features like session tracking and Cookies. There are also appendices on compiling and running Servlets. The reader is assumed to have some basic knowledge of HTML and Java programming."

This article describes advantages and disadvantages of Servlets vs CGI, How a Servlet works, and Where a Servlet can be used for.

This article describes the overall servlet architecture and what you need to develop your application with servlets. Also presented are several code examples to show you how to use the Servlet API, and compare it with CGI and proprietary server APIs where appropriate.

A brief introduction to writing your own first Java Server Pages (JSP). Covers several different editions of "Hello, World!" example. This article is the first excerpt of a full series from the book, Web Development with JavaServer Pages.

There are two primary types of tag conventions in Java Server Pages: Scripting-Oriented Tags and XML-Based Tags. Learning them gives you insight not only into JSP, but XML, too. This article is the second excerpt in a series from the book, "Web Development with JavaServer Pages."

One of the most exciting features of the new Java Servlet 2.3 specification is filtering. At first sight, Servlet 2.3 filtering is deceptively similar to existing legacy filters in Apache, IIS, Netscape Web servers and others. In reality, Servlet 2.3 filtering is a completely different design architecturally -- leveraging the object-oriented nature of the Java platform to provide a new level of performance. This article introduces you to filtering in Tomcat 4 and shows you how to make productive use of filters in your projects.

This article describes how to forward response from one Servlet to another and how to include response from the other Servlet. Discusses RequestDispatcher interface. Online demo available.

An article on updating records in the database using JDBC with Java Servlets. Every step from establishing a Connection to executing the UPDATE query is explained in detail. Online demo available.

This article discusses the anatomy of a JSP page. Discusses all the directives, scripting elements, actions and JSP tags which form part of the JSP page. This article provides good foundation for studying advanced JSP topics.

The corporate firewall is a double-edged sword. It helps prevent unauthorized access to the corporate Web services, but can disable access for legitimate clients. Due to the number of safety measures taken by system administrators, HTTP has become the universal entry mechanism to the corporate network. Where technologies such as CORBA and DCOM have failed because of the firewall, technologies such as SOAP have been developed to provide safe and reliable access through firewall protection. This article explores an alternative to SOAP, the use of Java objects over HTTP. In addition, it uses J2EE servlet technology as server-side middleware to the business data.

Tags are reusable code libraries and allow easier separation of HTML and Java code. This tutorial first introduces JSP custom tags and then moves forward to build a simple JSP tag. Every step has been explained in detail. Online demo available.

This tutorial is second in a series of tutorials about JSP tags. In this tutorial we will learn what are scripting variables in JSP tags and how to make use of them. Online demo available.
