The two principal products in the Java SE platform are: Java Development Kit (JDK) and Java SE Runtime Environment (JRE). The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications. The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. The following conceptual diagram illustrates all the component technologies in Java SE platform and how they fit together. What's New in Java SE Documentation

Add the Listener by selecting the test plan element (Add --> Listener -- > Monitor Results). By default, the Listener will select the results from the first connector in the sample response. The Connector prefix field can be used to select a different connector. If specified, the Listener will choose the first connector which matches the prefix. If no match is found, then the first connector is selected.

Introduction The Java TM 2 Platform Standard Edition (J2SE TM platform) is used for a wide variety of applications from small applets on desktops to web services on large servers. In the J2SE platform version 1.4.2 there were four garbage collectors from which to choose but without an explicit choice by the user the serial garbage collector was always chosen.

[ Home | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 ] Exercise 1: Drawing Lines Here's the source code for a first applet: import java.applet.*; import java.awt.*; public class DrawingLines extends Applet { int width, height; public void init() { width = getSize().width; height = getSize().height; setBackground( Color.black ); } public void paint( Graphics g ) { g.setColor( Color.green ); for ( int i = 0; i < 10; ++i ) { g.drawLine( width, height, i * width / 10, 0 ); } } } Start up a plain text editor and type in the source code. It's important that you use a plain ASCII text editor (such as "Notepad" on Windows, "SimpleText" on Mac, or "vi" or "emacs" on UNIX) to enter the source code; don't use a word processing application (such as "WordPerfect" or "Word") since they use a proprietary format for files.
Lesson: Applets (The Java™ Tutorials > Deployment)
This lesson discusses the basics of Java applets, how to develop applets that interact richly with their environment, and how to deploy applets. A Java applet is a special kind of Java program that a browser enabled with Java technology can download from the internet and run. An applet is typically embedded inside a web page and runs in the context of a browser. An applet must be a subclass of the java.applet.Applet class. The Applet class provides the standard interface between the applet and the browser environment.
In computing , an applet is any small application that performs one specific task that runs within the scope of a larger program , often as a plug-in . [ 1 ] [ 2 ] An applet typically also refers to Java applets , i.e., programs written in the Java programming language that are included in a web page . The word Applet was first used in 1990 in PC Magazine. [ 3 ] [ edit ] Applet as a standalone application Provided that an applet is hosted by an operating system , it can function as any other normal software application but performs only a small set of tasks.
Applet
Cette page est un résumé de ce que j'ai compris en créant mes applet et parcourant la documentation ; cela ne vaut peut-être pas les documentations complètes et rigoureuses qu'on doit pouvoir trouver sur le web ou dans le commerce, mais suffit pour simplement mettre en ligne une application Java. Une applet Java se construit sur le modèle suivant : Les 3 premières lignes servent à importer les bibliothèques Java nécessaires : la bibliothèque applet et des bibliothèques AWT qui servent à créer les composants graphiques (bouton, liste, zone de texte, ...) et à intercepter les événements (clic sur un bouton, ...). La classe "graphique", celle qui est hérite de Frame dans un simple programme java, doit maintenant hériter de Applet . Il n'y a pas besoin de constructeur, ni de fonction main . Cette classe peut bien sûr avoir des champs, des méthodes statiques et implémenter des interfaces comme n'importe quelle classe.

What is bottleneck? - Definition from Whatis.com
A bottleneck, in a communications context, is a point in the enterprise where the flow of data is impaired or stopped entirely. Effectively, there isn't enough data handling capacity to handle the current volume of traffic. A bottleneck can occur in the user network or storage fabric or within server s where there is excessive contention for internal server resources, such as CPU processing power, memory , or I/O (input/output). As a result, data flow slows down to the speed of the slowest point in the data path. This slow down affects application performance , especially for database s and other heavy transactional applications, and can even cause some applications to crash.What is input/output? - Definition from Whatis.com - see also: I
I/O (input/output), pronounced "eye-oh," describes any operation, program, or device that transfers data to or from a computer. Typical I/O devices are printers, hard disks, keyboards, and mouses. In fact, some devices are basically input-only devices (keyboards and mouses); others are primarily output-only devices (printers); and others provide both input and output of data (hard disks, diskettes, writable CD-ROMs).
