JavaRa - removing old Java versions

Posted by ClifNotes, Sep 2008, permalinkDisk CleanupSystem Maintenance


About three or four months ago, I noticed that I had about three or four older versions of Java installed on my PC in addition to the most current version. Why does Sun, the creator of Java do this to us? Their installer should always uninstall the older version before they update the new one.


I didn't like it and I manually uninstalled them. I had a real mess on my hands for a short while. I found that you had to uninstall them in the correct order and I hadn't done that. I ended up removing all of the versions and starting fresh.


CC wrote me this week and told me that he tried this JavaRa application and it works fine. JavaRa has only one job. It removes the older versions of Java. I wish I'd known about it months ago. It's gotten good reviews everywhere and it's open source freeware.


Quote from the website

JavaRa is a simple tool that does a simple job: it removes old and redundant versions of the Java Runtime Environment (JRE). Simply select "Check for Updates" or "Remove Older Version" to begin. JavaRa is free under the GNU GPL version two.


Java software in general and the Java JRE in particular allow you to run applications called 'applets' that are written in the Java programming language. You probably have Java JRE installed on your computer because these applets allow you to play online games, chat with people around the world, calculate your mortgage interest, view images in 3D, as well as many others.
