Linux Java Install

1. Java 2 SDK 1.4.2 Installation Notes for Linux
   Java 2 SDK, Standard Edition, 1.4.2 is supported on i586 Intel and 100% compatible platforms running Linux. For a list of supported Linux operating systems and desktop managers, see System Configurations. You should have about 75 megabytes of free disk space before attempting to install the Java 2 SDK software. A minimum of 32 megabytes of RAM is required. Recommended 48 megabytes of RAM. For issues, see the Troubleshooting section below and the Linux Notes section of the Release Notes. Also available is Known Problems on Non-Supported Platforms. 
                                    

2. Java Web Start Download
   Java Web Start software gives you the power to launch full-featured applications with a single click from your Web browser. Please follow the three simple steps to download, install and use the software, but before you start, we recommend that you bookmark this page to come back easily. The most recent release of Java Web Start is version 1.2, which is shipped as part of the Java 2 Platform, Standard Edition, v. 1.4.1 (J2SE 1.4.1).
                                                              

3. Install Java on Linux
   If you're not running Debian, and are instead running a different distro, then follow the following directions. The lastest Java Runtime Environment as of this writing is 1.4.2. To download your JRE, go to ftp://ftp.tux.org/pub/java/JDK-1.4.2/i386/rc1/ and download j2re-1.4.2-rc1-linux-i586-gcc3.2.bin (note that this distribution is for Linux running on Intel processors). 
   
   The following instructions are taken from the Blackdown README, located at ftp://ftp.tux.org/pub/java/JDK-1.4.2/i386/rc1/INSTALL-j2re . 
                                                               

4. Manual Download 
   To complete the download of the Java Runtime Environment, please select from the list below. Once you have Java software, you'll have access to a whole new world of interactivity. Please note that downloads are subject to our license agreement.
                                    

5. Installation Instructions 
   1. Go to http://java.com
   2. Click on Get Java Software button
   3. There are two types of installation packages. Linux RPM package or Linux self extracting binary file. Download the package     
       that best suits your needs.
   
   Note: Linux RPM (Redhat Package Manager) uses RPM to install the JRE. In order to use this method, you need to have RPM available on your system. Otherwise use the other option.
                   

6. Java on Linux
   This covers Java development and execution on Linux. Both commercially supported products and Open Source GPL'd software will be covered. Also see the YoLinux Java Servlets,Tomcat and Apache Tutorial. TogetherSoft.com - (recently purchased by Borland) - UML, source editing, debugging, GUI layout all tied in one multiplatform IDE. Borland JBuilder for Linux - See install procedures below. Complete IDE for building applications, JSP/Servlets, JavaBeans[tm], Enterprise JavaBeans and distributed J2EE applications. Comes with AppServer and Visi-Broker (Visigenics CORBA broker). Suports UML, SOAP, UDDI, WSDL. (Linux, Solaris, Mac OS X and MS/Windows) Oracle also sells a version of JBuilder under the Oracle brand name.

7. Use linux 
   You may want to install Java on your Mandrake Linux system for at least two reasons: as a plugin for your browser or to run Java applications. Use Linux at Home you'll find the list of all the articles available here. Some of them are targeted specifically at the Mandrake distribution but most of the tips are general enough to be used to other Linux distribution. At least, they will be working with minor adjustments.
                               

8. Installation Java
   Installing Java is pretty straight forward on Linux. Here are the simple Steps. This document talks about how to install Sun's Java SDK version 1.4 on any Linux machine. Accept the license and continue. Under the "Linux Platform", select "RPM in self-extracting file", it's about 30-35 MB. Download this .bin file and save it to a place on your Linux machine. Once it has been downloaded, login as root and switch to the directory where you saved the file. Execute './filename', where filename is the name of the file that you downloaded. The filename might be very similar to j2sdk-1_4_2_08-linux-i586-rpm.bin depending on what the latest version is. You may have to make the file executable by executing the 'chmod +x filename.bin' command.
                                         

9. Getting started with Java
   Write once, run everywhere: that's the slogan the Java community uses to propagate their language-of-choice. It's probably true, but only if you first manage to set up the beast on your box. This article gets you started with Java on Linux by showing you how to get the Java Compiler and Virtual Machine installed so you can run core Java programs. It also shows you how to set up a Java web application server. If you follow each step in this article carefully, you will end up with a full-featured Java application server. For the core Java, we will use Sun's JDK (Java Development Kit), although the IBM equivalent would work equally well. IBM's JDK is even known to be a little faster than the Sun JDK.
                             

10. Downloading the Java Runtime Environment
    A lot of people seem to be have trouble getting the Java plugin to work with Mozilla. I have no idea why. It's always really worked for me. :) As such I figured I'd write a document on how I went about installing Sun's Java RE 1.4.2 on my system. This is not a definative guide by the way, but it works for me™ and so I hope it works for you. My system is a Debian 3.0 (woody) Linux box running on i386 architecture. If you're not running Debian then don't let that put you off. These instructions are general enough so that they should work on most distributions, and even though they don't use a package manager to do the install they shouldn't mess up your system. They didn't mess up mine. (No guarantees though... :)
                   

11. What is Java and why do we need it?
    Java is a programming language that allows programs to be written that can then be run on more than one type of operating system. A program written in Java can run on Windows, UNIX, Linux etc. as long as there is a Java runtime environment installed. Some of the programs on this website have been written in Java, so you will need to install the Java runtime environment in order to run them. 
                    

12. Installing Java on your Linux System
    Java is a fairly important technology to have on any operating system. Countless Web sites make use of Java or JavaScript; programs such as Zend Studio are Java applications that require the Java Runtime Environment; and many developers develop in Java. Unfortunately, most Linux distributions do not ship with Java due to its license fee. Certain Java implementations are free, such as GCJ, or the GNU Compiler for Java, but it isn't Sun's Java implementation, which is arguably the better of the two.
                      

13. Java FAQ
    On Windows, Mozilla can be used with Sun's Java Runtime Environment (JRE). It can not be used with the Microsoft Java VM, as that can only be used with Internet Explorer. Also, versions of Sun's JRE older than 1.3.0_01 will not work. It is recommended that you use Java Runtime Environment 5.0 or later if possible. It is possible to install JRE 5.0 Update 6 from within Mozilla, using XPInstall technology. This is by far the easiest way to install Java. If you can not use XPInstall, you can download the JRE 5.0 Update 5 full installer and use that instead. On some systems, JRE 1.4.2 and later do not work. In this case, you can use JRE 1.4.1_07 until the issue you are having is resolved. Note that this release is no longer supported by Sun.     
                    

14. Installation Notes
    These instructions assume an i386 to i686 system (32 bit) with, an "always on" LAN or broadband connection configured "DHCP" and at least 10 GB of free disk space for the Fedora partition. Instructions for dual booting Windows and Fedora are included as well as as a section on setting up an nVidia GeForce graphics card. For the most part the steps should be followed in the order that they were written as certain programs should be installed and certain configurations made in order to facilitate later steps. However after the base installation is complete additional user selected program installations are, of course, optional. For reasons that will become obvious as the reader follows this guide the author highly recommends the installation of Yum, Apt, and Synaptic for the purpose of obtaining updates and applications in RPM form. Instructions for doing so are included.
                     

15. Obtain Java for linux
    Sun's Java is proprietary and not open source. But it is what we use for BibleDesktop and JSword. At this time there is no open source Java that will run our application. For that reason, you will need to get Sun's Java from them and install it. However, Sun's Java RPM does not install correctly. To install it correctly you will need to use JPackage's Java Package.
                   

16. Install Java on redhat
    This is a step by step How-To which explains how to install Java for the Mozilla browser on Red Hat 9.0. I searched around the net and did not find a good Java Installation How-To for Redhat 9.0, so I decided to write my own. I hope that this How-To is written so linux newbies will be able to set up their pc to run java based websites. The goal is to be able to run java based applications like chat rooms or games. What you are looking for is the Java Runtime Environment, as of September 2003 called J2RE v 1.4.2_01. There is also a developer's kit, called SDK, but unless you are writing java applications, you don't need it.
                                    

17. Java Development on linux
    While Java has promised developers and end users alike the realization of WORA (Write Once Run Anywhere), Linux has commoditized the operating system market. This open-source operating system, originally created by Linus Torvalds and distributed under the GNU General Public License (GPL), kicked off on October 5, 1991 with this usenet newsgroup post. Since that time, the Linux user base has grown to more than 10 million and the OS has become the fastest-growing platform in the global IT market, according to IDC. Here's the main reason why: the hardware used by Linux is typically much cheaper than that required by proprietary Unix operating systems, and it is usually faster as well. Clearly, combining Linux—a high-performance operating system that can be used for free—with low-cost hardware and Java makes for a flexible, reliable, and affordable enterprise-ready infrastructure, and thousands of IT shops are moving in that direction.
                                            

18. Install Java 3D
    If you already have a Java Software Development Kit (JSDK) or Java Runtime Environment (JRE) installed, then you can skip parts of this section. If you are using a JRE only, you'll have to get the JRE version of the Java 3D package and adapt these instructions. It is recommended that you have the lastest version of Netscape, which at this time of writing is 6.2.1, if you plan to install the Java PlugIn for netscape. It works, but you may (or may not) experience Segmentation Faults when leaving a page that contained a Java 3D applet. KDE Konqueror can also be used to view Java 3D applets. 
                     

19. Enterprise Java for linux
    This document was started January, 1999 by Gary Meyer ( gary@meyer.net) after several weeks of installing various open source and proprietary Enterprise Java products for Linux. "Enterprise Java" is defined as using the Java Enterprise APIs. This HOWTO is intended to benefit software professionals who are interested in evaluating, developing, or deploying Enterprise Java on Linux. Limited knowledge or experience in either Linux or Java is assumed. This document is Copyright (c) 1999-2001 by Gary Meyer and Greg Wilkins.

20. Integrate Java on the linux platform
    you need a programming environment. This is a very controversial subject, so please forgive me if I leave any out. If you want to work at the most rudimentary level, all you need is a text editor. If you're happy with vi, Emacs, or XEmacs, more power to you. If you need a little more from your environment, you might want to consider one of the free commercial IDEs. Instead of providing you with my own pathetic list of IDEs, let me point you to JavaWorld's excellent list (provided in the Resources section below). Personally, I just love VisualAge; however JBuilder is an excellent choice as well. Again, these decisions are best left to personal preference. Look at the list, read the descriptions, and try one (or more). Many are free, but others will cost you.
                 

21. Getting Java Software for your Platform
    The basic Java environment consists of a web browser that can play Java applets, a Java compiler to turn to Java source code into byte code, and a Java interpreter to run Java programs. You'll also need a text editor like emacs, TextPad, or BBEdit. Other tools like a debugger, a visual development environment, and a class browser are nice but aren't absolutely necessary. It isn't necessary to get all pieces from the same source. For instance, your web browser will probably be the same copy of Internet Explorer or Netscape you already use. The rest will probably be provided by Sun's Java Developer Kit (JDK). Sun publishes versions for all the platforms it supports (Windows, Solaris, X86 Linux) and third parties have ported it to other platforms.
                                  

22. Java Programming on Linux
    The point of Java Programming on Linux is that while Java software generally looks the same from platform to platform--that's the glory of its portable nature--the tools for generating that software differ among operating systems. In this book, Nathan Meyers presents a comprehensive picture of the Java universe from the point of view of people who run Linux. Though this book does include some general material on Linux and Java (both of which receive better coverage elsewhere, in dedicated volumes), it is the best available catalog of Linux development tools for Java. Meyers documents scores of tools (including compilers, debuggers, virtual machines, just-in-time compilers, and various utilities), some of which he developed himself, in considerable detail.
                        

23. Other Java alternatives for Debian
    If the Java packages provided in Debian are not sufficient for your needs you might need to take a look at other alternatives. Please understand that these alternatives are not supported by the Debian project directly, you might get help, however, from the debian-java mailing list if you encounter issues with them. Some of the alternatives presented use Debian packages which is convenient, since the user/administrator does not need to care on installation issues. However, mixing packages that come from a source which is not the Debian project might cause conflicts with your installation some times. Of course, Debian tries to integrate as many free software efforts as possible, so some of the alternatives described below might (if license permits) be included in Debian in the near future. 
                                     

24. Installing Java
    If Java is not installed, install the Java Run-Time Environment (JRE) or the Java Software Development Kit (SDK). Set the JAVA_HOME environment variable to point to the base directory of your Java installation. This will enable Tomcat to find the right Java installation automatically. This may already be setup for you by your Java SDK installation.
                            

25. Java Comm for Linux (JCL)
    Java Comm for Linux is a set of free drivers for Sun's official serial driver interface: CommAPI. It allows you to use Linux serial (and eventually parallel ports) in an OS independent manner. JCL actually supports any operating system supported by RXTX, but Linux is the operating system I've tested it on. Windows 95/NT users can use Sun's standard CommAPI - you don't need JCL or RXTX.
                                                                      

26. Java 2 Standard Edition
    The JRE class files that are distributed with JRockit come directly from Sun except for a small number, which are tightly coupled to the JVM and are therefore overridden in BEA JRockit. The class files that are overridden are in the java.lang, java.io, java.net and java.util packages. There are no omitted classes.
                                             

27. Install Java in Linux
    By default gcj compiler will be installed while installing the Linux OS itself. But for having many options like in DOS using Java and Javac commands, we will generally download the Java SDK for Linux directly from the SUN  micro systems web site. The file name is jdk-1_5_0_06-linux-i586.bin. It is a self extracting bin file. First we have to change its permission using chmod 777 to make it executable and then run it using ./filename.bin It will install the required Java software on the system. To run commands Java and Javac, we should use complete path. They will be located in the bin directory inside Java directory created while extracting the above bin file.
                        

28. Install multiple Java environments on Linux Box 
    PATH controls where executables will be found - make sure the executables you want will be found first. CLASSPATH controls where classes will be found. Different environments have different requirements for the CLASSPATH - you often do not need to set it at all. But if you do set it, be sure not to include components from Java environments other than the one you're running.  JAVA_HOME is not used by JDK1.2 and later environments, but some earlier Java environments did use it, and some scripts depend on it. If this variable is set, make sure that it does not point to a different Java installation than the one you're trying to use.
                         

29. BOOK Programming Linux Games
    They do however also say this in 'conclusions': "In hindsight, Tcl was not an especially good choice for the scripting engine. It works in this case, but it's not a very good solution for number crunching or managing large amounts of data. If I were to rewrite Chapter 6, I would probably choose a Lisp variant such as Scheme."
                

30. Windows vs. Linux Game Server
    I'm writing an article at my website, Game Server Review, about whether to choose a Linux or a Windows game server. I know the basics (Linux is more stable, secure, faster, etc.) but would like to get more in depth. So I'm here to do some research. I'm looking for some neutral comments here about both Windows and Linux shared game servers (not dedicated machines). Some benefits of each from the perspective of a game server renter (not a game server provider) would be very helpful. If you are interested in writing the article, let me know. I write most of the articles for my website but always like submissions from other people. I can't pay you unfortunately, but I would be more than happy to allow you to put a little bit about yourself and your website at the end of the article.
                    

31. Advancing Linux Game Development
    A very old thread was brought back from the dead ("thread necromancy" as the poster phrased it) in the Community Chat section, but in order to attract attention from the group that would be most effected, I decided to post this with a link to it. Post #32 (the second one on that page) is where the new discussion starts, and I just wanted to bring this to the attention of the people here in the gaming forums. For feedback, comments, suggestions, etc., I suggest that they be left in the linked thread.
                    

32. Reliable LINUX game server admin wanted
    We searched around and seen someone had a simular problem and wanted some people to install some games for them on a control panel system 'gcp' and we are looking for simular help. We recently signed up with gcp and got some games installed but we are having some major problems on getting them to work on the system.
                     

33. Linux Game of the Month: Childsplay
    Okay, so maybe it takes a while to learn to type. Nevertheless, kids are drawn to computers at an early age and parents invariably start looking for programs their kids can enjoy and learn from. And so, it is to the parents of young Linux users who are reading this column that I dedicate today's game. It's called, appropriately, Childsplay, and calling it a game may not be quite as appropriate since it is actually a collection of games. Childsplay is an engine that handles plugins, each game being a plugin. The games are geared for an age range from 2-7. As such, they are all fairly simple for the readers of this column but somewhat more challenging for your young children.
                  

34. Linux Game of the Month : Pingus
    After spending any amount of time playing (and yes, when necessary, working) with Linux systems, you can't help but notice that penguins do tend to figure prominently in the mythos of the operating system. Penguins show up everywhere — from the Linux mascot, Tux (designed by Larry Ewing), to the numerous variations on the penguin theme, you can't go near a Linux system, magazine, T-shirt, mouse pad, coffee mug, or book, without running into some kind of penguin. That's okay for most people because, well, penguins are cute. If you want to know who is responsible for this whole penguin-mania, blame Linus Torvalds, Linux's creator. When asked what he envisioned for a mascot, Linus replied, "You should be imagining a slightly overweight penguin (*), sitting down after having gorged itself, and having just burped. It's sitting there with a beatific smile — the world is a good place to be when you have just eaten a few gallons of raw fish and you can feel another 'burp' coming."
