    Java runtime environment updates (XP SP2)

    In Add/Remove Programs I see a lot of updates of Java runtime environment listed each claiming to to take up a sizeable amount of disc space, and in Crogram files they do seem to take up a lot of MBs. (See screenshot.)

    Do I really need all of these? Can I clear some space by uninstalling some of these updates, or are they cumulative? Should I remove the lot and start again, or what?

    Ian,
    I went through this cleanout by removing all the Java stuff and going for a new lot from the Sun site. Now I only have two remaining and I also went into the folders to clean out the non-English readme and license files.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Ian,
    More info from the Sun FAQ page.

    Does the software update from Sun erase my previous version of Java?
    No. It installs a newer version of the Java Runtime Environment while leaving the existing versions intact. For example, a client machine can have the J2SE versions 1.3, 1.3.1, 1.3.1_02, and 1.4 installed at the same time without conflict. This is useful for when application provider A has only certified their application on version 1.3, while application provider B requires version 1.4 for additional features or functionality. There are no conflicts or collisions between JRE versions, as they all peacefully co-exist.

    So, no harm taken if you leave them, I suppose. I elected to remove them

    For some reasons, Sun Java doesn't remove the previous versions when installing a new one. You can safely remove all older versions (current versions: 1.4.2_10 and 1.5.0_06 ).

    If you do not specifically require v. 1.4.2, you can install v. 1.5 only.

    Thanks. Time for some tidying up, I think.
