Java Plug in technology, included as part of the JRE, establishes a connection between popular browsers and the Java platform. This connection enables applets on web sites to be run within a browser on the desktop. Java Plug in is automatically enabled for supported web browsers during installation of the JRE. No user intervention is necessary. See Applet Developers Guide for more information about Java Plug in technology. Note In Java SE 7, the version of Java Plug in that is available in versions of the JRE prior to Java SE 6 Update 1. However, this earlier version of Java Plug in is still shipped with Java SE 7 for compatibility purposes but is no longer fully supported. It will be removed in a future release. For backward compatibility purposes, you can specify which Java Plug in is used to run applets in the Java Control Panel. To specify this, run Java Control Panel, go to the Advanced tab, Java Plug in node, and toggle the check box labeled Enable the next generation Java Plug in. See Java Control Panel for more information. In addition, you can use the Java Control Panel to manage multiple JRE versions used for applet execution. Java Web Start is an application deployment technology that gives you the power to run full featured applications with a single click from your Web browser. You can now download and run applications, such as a complete spreadsheet program or an Internet chat client, without going through complicated installation procedures. With Java Web Start, you run applications simply by clicking a web page link. If the application is not present on your computer, Java Web Start automatically downloads all necessary files. It then caches the files on your computer so the application is always ready to be run anytime you want either from an icon on your desktop or from the browser link. No matter which method you use to run the application, the most current, available version of the application is always presented to you. See Java Web Start for more information. This section covers the following topics If you have a previous version of Java Web Start, do not uninstall it. Uninstalling it will cause the download cache to be cleared, and all previously installed Java Web Start application data will have to be downloaded again. This new version will write over previous installations and automatically update browsers to use this new version. EclipseInstallation Eclipsepedia. Excel Templates For Kpis For Sales on this page.

Install a JVMIf you are using Eclipse to do Java development, install a JDK. A Java Development Kit JDK includes many useful extras for Java developers including the source code for the standard Java libraries. Regardless of your operating system, you will need to install some Java virtual machine JVM. You may either install a Java Runtime Environment JRE, or a Java Development Kit JDK, depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK. If you arent planning to use Eclipse for Java development and want to save some disk space, install a JRE. If youre using Windows, you may already have a JRE installed, but upgrading wont hurt. If youre using Mac, and you dont have a JDK installed, you may get a bogus message from the OS stating that you should install the legacy Java SE 6 runtime. Installing that will not solve the problem, because recent versions of Eclipse require a higher version. If you install just a JRE, and not a full JDK, that error message will persist. You must install a full JDK. If using Linux, read this. JREJDK Sources. Be sure to install a JVM with the same bit level as Eclipse. JRE to run 3. 2 bit Eclipse install a 6. JRE to run 6. 4 bit Eclipse. There are several sources for a JREJDK. Here are some of the more commonpopular ones listed alphabetically. Download Eclipse. Download Eclipse from the Eclipse Downloads Page. There are several package choices. Note that you can install the features from any package into any other package.

Some people report success when initially decompressing Eclipse into a root directory e. Program FilesEclipse. Configure Eclipse to use the JVMIt is strongly recommended to configure Eclipse with the specific JVM that you want. See the instructions at Eclipse. This is a very important step to be sure that Eclipse is using the JVM you intend and cant be influenced by any other software that might alter your system. The JVM used to launch Eclipse has no affect on whether it can compile Java sources for other Java language versions. Extending Eclipse. Use the Help Install new software. Kepler features to your Eclipse installation you can, for example, use this option to add CC development support. Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via the Eclipse Marketplace Client Help Eclipse Marketplace. Note that not all Eclipse packages contain the Eclipse Marketplace Client. Troubleshooting. Java was started but returned exit code 1. If youve installed Eclipse but are having trouble getting it to run, the most likely cause is that you have not correctly specified the JVM for it to run under. You may need to edit the eclipse. Another common mistake on Microsoft Windows is a mismatch between the bittedness of Eclipse and the JVMJDK. This is the most frequent cause of an Error 1. Eclipse requires a 6. JVM, and 3. 2 bit Eclipse requires 3. JVM you can not mix and match between 3. Eclipse you installed matches the JVMJDK that youre using to run it and make sure youre using eclipse. JVM used to run Eclipse, described above. As a simple test, open a Command Prompt window, move to the directory that is pointed to by the vm argument in your eclipse. Its often simplest to download a version of Eclipse that will work with whatever Java you already have installed. To open Eclipse you need to install the legacy Java SE 6 runtime. On more recent versions of the Mac, if you dont have a full JDK of an appropriately high version installed, the OS produces this bogus message. Installing any JRE will not eliminate this problem. A full JDK needs to be installed on the Mac. Extraction requires a password or otherwise fails on Windows. Eclipse downloads are not password protected. This is a known problem with the built in decompression utility on all current versions of Windows. We recommend that you either download the installer or use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download.
