hi
I am running fedora core6 plus all the latest updatesand patches
my java runtime enviornment is totally screwed up can any body help here are some of the screenshots...

please some body help me
thanks in advance

None of the websites you refer to here have any java embedded on their pages, but they do use JavaScript. It appears that JavaScript isn't being processed in Opera.
I have the "NoScript" Firefox extension installed, and the pages pretty much show up as they do for you in Opera if JavaScript is disabled for those pages.

Anyway, check your JavaScript settings in Opera, not your Java settings. Besides, even if the pages used embedded Java, since the pages render perfectly fine in Firefox this would indicate the problem is with Opera, not Java.

Do you use compiz? Unfortunatelly, sun JRE does not work properlly with compiz. Try disabling desktop effects and chceck if this helps.

I am not sure that the Sun JRE would have anything to do with it. I have fc6+desktop effects
and Sun's Java running for internet banking and it is all fine.

To the original poster: I think the problem is with the Javascript not Java per se. Javascript -
inspite of it's name - has nothing to do with Java and you do not even have to have Java installed
to run it. JS is self contained within the browser.

BTW, I could not see the screen shots of the original post's links.

Hi,

> ... my java runtime enviornment is totally screwed up ...
I haven't followed any of the links you provided,
and I don't know whether or not any of the problems
you experience at these web sites have to do with
your JRE ...

> There are 2 programs which provide 'java'.
> /usr/lib/jvm/jre-1.4.2-gcj/bin/java
> /usr/lib/jvm/jre-1.5.0-sun/bin/java
... however, the fact that you have two
JRE's installed suggests to me that the
problem could be in your PATH statement.

It's not enough for the JRE to be installed:
Any Java programs that you want to use must
be able to find it. If you have two JRE's
installed, your PATH statement could be
pointing to the wrong one. Or, perhaps
it's not pointing to either one.

I would suggest that you start by reading
my article about this:

Best regards,

Tom

OK, just to be absolutely clear:

The Opera / website problem is with JavaScript, NOT Java. Specifically, it is with Opera's handling of the JavaScript code. JavaScript is loosely based on Java (well, actually the developers of JavaScript used this name to increase recognition, initially it was called LiveWire and then LiveScript), but they are distinct.

You may very well have issues with Java as well, but they are completely unrelated. The jrelinux article by Tom has a number of issues with it, although if your setup happens to be similar to his then his advice might help with any Java problems.

ok i got that about javascript but what about limewire

Did you tried to switch off desktop effects? Unfortunatelly, it definatelly is related to Java JRE. Since version 6 of Java, it uses some offscreen rendering which seems to be incompatible with compiz. If I switch it ON on my computer, I have exactly the same problem. Java windows are not rendered at all. However after switching OFF, everything works well.

actually i have been using beryl window manager when i switch back to metacity its fine but when in beryl that is what is happening can any body tell the solution

Ok, then add the following to your ~/.bash_profile (and then log out and back in):BTW you might have considered mentioning you were using Beryl in your original post, especially since Metacity worked fine!

sorry for forgetting that but i tried ou metacity only later

thanks anyway

Hello there,

To test for Java Applet support in Firefox and Mozilla you should do the following:

1. Browse to this website: http://java.com/en/download/installed.jsp
2. Click "Verify Installation"

If you are using the Sun JRE and you want to view and use Java Applets in Firefox or Mozilla, you need to make a symbolic link. (The good news is that both Firefox and Mozilla share SOME of the same settings so these directions are the same for both.)

The general idea is to link the "libjavaplugin_oji.so" file from your Java installation to your mozilla plugins directory.

You can either use your private Mozilla plugin directory that sits in your home directory or the global one for all Mozilla users on your Linux box. I'll demonstrate the former here. That's easier. It should not require the "su" command. lol...

1. In a command window type: cd $HOME/.mozilla/plugins
2. Type: ln -s /usr/java/j2sdk1.4.2_11/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

(If you installed the Java software in any other location besides /usr/java/ or if you are using a different version of Java than I am using, you will need to adjust the command in number 2 to work for you!)

You may just want to use the find command to find where the "libjavaplugin_oji.so" file lives. Use the one that lives in the "jre/plugin/i386/ns610-gcc32" directory inside your Java installation!

I think that http://java.sun.com/ might contain more information about this plugin and how to use it. I would highly suggest browsing that site for more information! :-)

Sincerely,
