Install Eclipse 3.2+
Eclipse - http://www.eclipse.org/
Note: If you already have eclipse 3.1.x installed, your best best is to start over with a fresh install rather than attempting to upgrade
Note: If you have not installed eclipse already, you should download the WebTools Platform: All-in-one package for Eclipse 3.3+ which includes Eclipse and all of the necessary webtools packages, this is much faster and easier than downloading them seperately, you can skip the WebTools step if you do this, here are instructions to install the Eclipse WebTools
Download the newest stable version http://www.eclipse.org/
Extract the downloaded file to /opt
Windows users should extract to c:\
Mac users should use the installer and put it in Applications
Run eclipse to verify it works (/opt/eclipse/eclipse)
Windows users: c:\eclipse\eclipse.exe to run eclipse
Note: If it does not work, there is probably a problem with your java install
Set the memory settings for Eclipse
The default memory settings for Eclipse are much too low to handle the number of webapps in a full Sakai installation
Shutdown eclipse if it is running
Edit the eclipse.ini file in the directory you extracted/installed eclipse
Change the settings from something like this:
-vmargs -Xms40m -Xmx256mto something like this (leave any params that do not match these alone):
--launcher.XXMaxPermSize 256M -vmargs -Xms128m -Xmx1024m -XX:+UseParallelGCWindows users should not use notepad to edit this file, use wordpad or edit (command line)
Mac users will need to take additional steps to edit the eclipse.ini file
Control-click on the Eclipse Application icon and select Show Package Contents
Double-click on the Contents folder
Double-click on the MacOS folder, the eclipse.ini file should be here
Full path: eclipse/Eclipse.app/Contents/MacOS/eclipse.ini

Startup eclipse if it is not running
Select Window -> Preferences -> Java -> Installed JREs
Select the current installed JRE
Click the Edit button
Click Browse and navigate to the home directory of your JAVA installation (e.g. /opt/java)
