Java!

wakou · October 10, 2009, 2:12pm

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

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.

Use Java from Sun. As here. Remove others:

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.

@wakou

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