How to Install: JDK 6

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

Overview

Note: the new laptops in 2007 and 2008 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, which includes CSSE220 and 221 students.

Follow these instructions to install:

J2SE 6.0 – Java 2 Platform Standard Edition 6.0, Update 6, which includes:

• JDK 6.0 Update 6

  The J2SE Development Kit (JDK) supports creating J2SE applications

• JRE 6.0 Update 6

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

Installing JDK 6

Do the following when you are on campus – it is too slow otherwise.

1. Login to an Administrator account (e.g., localmgr)
2. 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 → Add or Remove Programs for the above two items.

3. Click this link to the installer for J2SE 6.0 Update 6 and select Run.
4. Follow the instructions for installation, accepting all defaults
   • Especially: install the software to the default folder
   • This installation installs both the JDK and JRE
5. Restart your computer if directed to do so.

For trouble-shooting instructions, 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 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.

Beginning in the 2007–08 academic year, new Rose laptops came 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. Login to your regular user account.
2. If you have a prior version of the JDK API documentation, uninstall it. This just involves deleting the docs folder.
3. 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.
4. Extract the contents of the zip archive (however your zip extractor does this) 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.
