How to Install: JDK 6

Rose-Hulman Institute of Technology –
Computer Science & Software Engineering

Overview

Note: All new laptops since 2007 came with Java 1.6 (also called Java 6). These directions are intended for anyone needing to do a clean install or wanting the latest JDK update.

Follow these instructions to install:

J2SE 6.0 – Java 2 Platform Standard Edition 6.0, Update26, which includes:

• JDK 6.0 Update 26

  The J2SE Development Kit (JDK) supports creating J2SE applications

• JRE 6.0 Update 26

  The J2SE Runtime Environment (JRE) allows end-users to run Java applications

Download and Install JDK 6

Do the following when you are on campus or somewhere with a fast internet connection. It may take a little while.

1. If you have a version of Java prior to 6.0 , uninstall your existing versions of:
   • J2SE Development Kit
   • J2SE Runtime Environment

   Use Control Panel → Uninstall a Program for the above two items.

2. Click this link to the installer for J2SE 6.0 Update 26 for your laptop or another 32-bit Windows machine.
   If you have a 64-bit Windows machine, use this link .
   Select Run.
3. Follow the instructions for installation, accepting all defaults
   • Especially: install the software to the default folder
   • This installation installs both the JDK and JRE
4. Restart your computer if directed to do so.

For trouble-shooting instructions or for other hardware/operating systems (such as Linux), visit Sun's site for downloading Java. You do not need to go to Sun's site unless you want additional information. We maintain a local copy of the regular installer. Note: JDK 6.0 was once known as JDK 1.6, so certain folders and filenames use 1.6 as the version number instead of 6.0.

Download and unZIP the  Java Documentation

Sun provides HTML documentation for the Java Development Kit (JDK) Application Program Interface (API). By installing the documentation and configuring Eclipse, you can access the documentation by pressing the Help key in Eclipse.

     All Rose laptops come with Java 6 documentation installed. If your laptop includes the directory c:\Program Files\Java\jdk1.6.0_XX\docs, (where XX is a two-digit number) you may skip this step.

1. If you have a prior version of the JDK API documentation, uninstall it. This just involves deleting the docs folder.
2. Regardless of whether or not you had an existing, prior version of the documentation, click this link to the local zip archive for the JDK Documentation.
3. Extract the contents of the zip archive (The simplest way will be to open the zip folder in one window and the target folder in another and drag the document from one to the other) to c:\Program Files\Java\jdk1.6.0_XX. (Note that is jdk, not jre.)
   Warning...this BIG file takes a long time to unzip.
4. Double-check by making sure that you can get to C:\Program Files\Java\jdk1.6.0_26\docs and that the docs folder has seven folders and a file in it.
