LEARN JAVA PROGRAMMING - HELP AND JAVA LANGUAGE, J2EE TUTORIALS

This chapter has been leading us gently through the JavaServer Faces technology. More importantly, in it, Budi teaches ushow to write an online survey application to get a feel for how this great technology works. This chapter prepares you for the next chapters by introducing the JSF Application Programming Interface (API) and the Application Configuration file. This excerpt comes from chapter two of JavaServer Faces Programming, by Budi Kurniawan (McGraw-Hill/Osborne, ISBN 0-07-222983-7, 2004).

We continue with part two of Chapter 2 of Introduction JavaServer Faces Programming, by Budi Kurniawan (McGraw-Hill/Osborne, ISBN 0-07-222983-7, 2004). This section deals with the ActionListener and Component Tree, as well as validation and navigation for your JSP pages.  This chapter prepares you for the next chapters by introducing the JSF Application Programming Interface (API) and the Application Configuration file.

This chapter gently introduces the JavaServer Faces technology. More importantly, it teaches you how to write your first JSF application to get a feel for how this great technology works.  In addition to the sample chapters, this chapter prepares you for the next chapters by introducing the JSF Application Programming Interface (API) and the Application Configuration file. This excerpt comes from chapter two of JavaServer Faces Programming, by Budi Kurniawan (McGraw-Hill/Osborne, ISBN 0-07-222983-7, 2004).

Today, Budi walks us through a refresher and brief overview of server JSP programming. Today's portion covers JavaServer Pages (JSP), with a thorough overview of JavaBeans and Tags. This excerpt comes from chapter one of JavaServer Faces Programming, by Budi Kurniawan (McGraw-Hill/Osborne, ISBN 0-07-222983-7, 2004).

Today, Budi walks us through a refresher and brief overview of server JSP programming. Today's portion covers Servlet technologies, including servlets and Tomcat. This excerpt comes from chapter one of JavaServer Faces Programming, by Budi Kurniawan (McGraw-Hill/Osborne, ISBN 0-07-222983-7, 2004).

The gzip format is the de facto standard compression format in the UNIX and Linux worlds.  In a previous Dev Shed article titled Zip Meets Java, Kulvir demonstrated how to use the java.util.zip package to programmatically manipulate files in the ZIP format.  In this article, we’ll cover how to use the java.util.zip package to create and read files using the gzip format.

The ZIP file format has become extremely popular for the distribution and storage of files... The java.util.zip package allows for the programmatic reading and writing of the ZIP and GZIP formats. As you’ll see in this article, the API for reading and writing ZIP files is pretty straightforward to use... In this article, I’ll take you through a Java program that creates of a ZIP file and also walk you through another Java program that unzips the file we created.

Last time, we mastered some basic UI components and worked on how to add them to panels, organize their layout, and manage their events. Having covered all the basic techniques that we’ll need to get started with Java interface programming in our first article, Java's Basic User Interface Components, we will move on to some advanced UI components. Today, I’ll be covering scrolling lists, scrollbars, and canvases, and their functionality. It is amazing to see how many of complex tasks are simplified with the help of these advanced user interface components.

To simplify user interaction and make data entry easier, you can use java controls. Controls are components, such as buttons, labels and text boxes, that can be added to containers like frames, panels and applets. The Java.awt package provides an integrated set of classes to manage user interface components.

A well laid out user interface is an effective means of making applications user-friendly. It is typically used by organizations for accepting orders from customers, getting customer’s feedback on a product, for conducting a market survey on the latest trends in economy.

With the skills that you have developed so far from Part I of the tutorial, you can design a graphical user interface with beauty and easy. Let us refresh ourselves before we proceed, Events are method calls that Javas windowing system performs whenever any element of a user interface is manipulated.

In life, you encounter events that force you to suspend other activities and respond to them immediately. In Java, events represent all activity that goes on between the user and the application. Java's Abstract Windowing Toolkit (AWT) communicates these actions to the programs using events.

One of the most exciting features about JSP is the ability tobuild and use custom "tag libraries" in your JSP applications. In thisarticle, find out why tag libraries are a Good Thing, and read about how toget and install custom tag libraries for common tasks.

In this week's episode, find out how the JSP Exception objectprovides developers with a graceful way to recover from script errors. Andthen take a quick tour of the JSP directives you need to know in order tointegrate standalone JavaBeans into your JSP scripts.

Now that you've mastered the basics, it's time to bring out thebig iron. This week, The JSP Files explores the various techniquesavailable to "maintain state" on a JSP-based Web site. Learn about theCookie and Session objects, find out how to build a cookie-based hitcounter, and read about a simple yet effective way of protecting sensitiveWeb pages with the Session object.
