    Default Java!

    I have been having some problems with a java applet(?) in FF 3.5.3. This is the "Chat-room" of a forum hosted on the usual vBulletin softs with the chatroom provided by Java Chat Software - AddonChat.
    At first attmpting to use the chat would immediatly crash FF......
    This would also happen if I went to the Sun/Java test page here:
    How do I test whether Java is working on my computer?

    I blindly hacked around yesterday and and found some updates and installers (!), incuding a very flakey search update from inside FF, Tools>manage content plug-ins. It will not allow me to cut/paste, here is the output from
    Code:

    How do I test whether Java is working on my computer?

    Now works, (saying update available, not a clicky link tho')
    as do the testing scripts at:

    Java Tester - Is Java Enabled?
    Java Tester - What Version of Java Are You Running?

    I can now also get in to the chat room, I can "see" myself in there, and see what I type, but others cannot, nor can I see what they type to me.

    Should I somehow get rid of all but the latest in FF (I would not know how!, "manage content plug-ins" is flakey in the extreme!)
    Should I update java via YAST, if so should I uninstall older java first?
    If so how do I do that?
    Should I, and how do I for instance remove ALL java from my machine and start again?

    As per the provided data, I would say you have a mix between the 2 java
    packages (IcedTea and Sun Java).

    Open a console an (as root) run:

    stthpc:~ # update-alternatives --display java

    It will tell you what java version is being used by default. It should point
    to Sun's Java.

    Oops, that seems the problem. Your default java is openjdk instead Sun's
    one.

    Try setting the Sun's Java, instead. Open a console and as root, type:

    update-alternatives --config java

    And follow the on-screen steps, IIRC it was easy to select one or
    another :-)

    If in doubt, just ask.

    Default Re: Java!

    It is not OK. Look again.
    The Sun Java and the OpenJDK are different. Just use Sun versions. See my screen again.
