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

Overview

Follow these instructions to install:

• J2SE 6.0 – Java 2 Platform Standard Edition 6.0, Update 12, which includes:

  • JDK 6.0 Update 12 — The J2SE Development Kit (JDK) supports creating J2SE applications
  • JRE 6.0 Update 12 — The J2SE Runtime Environment (JRE) allows end-users to run Java applications

• JDK 6.0 documentation

Installing JDK 6

Do the following when you are on campus – it is too slow otherwise (they require downloading files of about 75 MB and 60 MB).

1. Login to an Administrator account (e.g., localmgr)
2. Open

   Start → Control Panel → Add or Remove Programs

   and uninstall all your existing versions of Java prior to Version 6, Update 12.
   • They may be listed as something like either or both of the following — if the update is less than 12, delete it!
     • Java(TM) 6 Update 11
     • Java(TM) SE Development Kit 6 Update 6
3. Manually delete all folders whose names begin either jdk or jre beneath

   C:\Program Files\Java

4. Click this link to the installer for J2SE 6.0 Update 12 and select Run.
   • If you are running 64-bit Windows (if you are not sure, then you are NOT running 64-bit Windows!), use this link instead.
5. Follow the instructions for installation, accepting all defaults
   • Especially: install the software to the default folder
   • This installation installs both the JDK and JRE
6. Restart your computer if directed to do so.
7. Open this link to the local zip archive for the JDK Documentation and extract the contents to

   C:\Program Files\Java\jdk1.6.0_12 .

   • Note that you extract to jdk and NOT jre.
   • When you are done, confirm that you have a folder called

     C:\Program Files\Java\jdk1.6.0_12\docs

     that has many folders directly beneath it — make sure that you don't have docs below docs.
   • Extracting this big file may take 5 to 15 minutes on your computer.
8. Sanity check: Check that you have the following:
   • Beneath C:\Program Files\Java\ — just jdk-1.6.0_12 and jre6 (and nothing else)
   • Beneath C:\Program Files\Java\jdk-1.6.0_12\ — several folders and files, including docs
   • Beneath C:\Program Files\Java\jdk-1.6.0_12\docs\ — several folders and files

If you have trouble with any of the above, get help from a lab assistant in the CSSE lab (Moench Hall, F-217) during assistant office hours.
