Unable to get Java to work in Firefox3

I cannot get java to be recognised in FF3. I've installed it several different ways, apt-get, website, several versions, etc. No-go.

There were no errors shown when installing java.

Can someone please help me figure out why it's not working?

I'm using Fluxbuntu 7.10.

Are you running 32 bit (i386) or 64 bit (AMD64) Fluxbuntu?

It does appear that the only version of Fluxbuntu is a release candidate and not a stable release.

I'm using 32-bit fluxbuntu.

Can you post the output of java -version?

java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea Server VM (build 1.7.0-b21, mixed mode)

you may need to link the java plugin to your firefox3 plugin folder
i am not sure where it is on " Fluxbuntu " but for fedora8 it is
/usr/lib/jvm/jre-1.7.0-icedtea/lib/i386/gcjwebplugin.so
then start FF and type into the address bar

Code:

about:plugins

and you will get a list of installed plugins

GCJ Web Browser Plugin 1.4

File name: /usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0/jre/lib/i386/gcjwebplugin.so
The GCJ Web Browser Plugin executes Java applets.

I tried that, but whenever I went to http://www.java.com/en/download/installed.jsp and clicked 'verify java version' button, FF immediately crashed.

I have FF 2.0.0.17 and 3.0a8 (Gran Paridiso beta). Both browsers immediately crash-killed at that verify site.

I them removed the java.so from the plugins folder and retried, no crash, but it doesn't detect I have java installed.

Contents of ~/.mozilla/plugins:
flashplayer.xpt libflashplayer.so

It seems I have two versions of java installed...?

Any ideas how to get FF2 and FF3beta to understand and use java?

Thanks in advance!

Install sun-java6-jre and galternatives. Use the latter to switch java and the firefox and xulrunner java plugins to the sun java plug-in.

That did not work for either browser (FF2 or 3beta).

Ugh. This is so frustrating.

Try sudo update-alternatives --config java

jurgen@Selena:~$ sudo update-alternatives --config java

There are 2 alternatives which provide `java'.

Selection Alternative
-----------------------------------------------
+ 1 /usr/lib/jvm/java-6-sun/jre/bin/java
* 2 /opt/jdk1.6.0_10rc/bin/java

Press enter to keep the default[*], or type selection number:

You may also want to remove any java providers other than the one from sun.

I tried all of that. No luck.

I wonder what is wrong??

I removed all other instances of java, reinstalled it, did the config stuff, rebooted, and it still doesn't work.

:sigh:

apt-get install sun-java6-plugin sun-java6-jre sun-java6-bin
then run update-alternatives --config java and choose sun-java

If none of that works, how did you install firefox? Using apt-/synaptic or are you using the Mozilla firefox? If your using the Mozilla Firefox and not the version available in your repos you need to link or copy the plugins to the appropriate dir.

***Installing sun-java6-plugin worked!! Thank you for your help, all of you!!***

I installed firefox via apt-get as fluxbuntu comes with a japanese browser (kazehakase) that is quite stripped down and I did not like it.

I'm using both Mozilla Firefox 2.0.0.17 and Firefox Gran Paradiso 3.0a8.
