[SOLVED] Java not working with iceweasel

cccc · 02-02-2012, 01:58 PM

hi

I've Squeeze with Gnome and I'm using iceweasel browser.
I've installed sun-java6-jre and sun-java6-plugin, but java in iceweasel doesn't work.
BTW Java is enabled in the browser settings.

Code:

# java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

# update-alternatives --config java
There is only one alternative in link group java: /usr/lib/jvm/java-6-sun/jre/bin/java
Nothing to configure.

I've solved this problem, the link to java plugin, installed automatically seems to be not OK:

Code:

# ls -la /etc/alternatives/iceweasel-javaplugin.so
lrwxrwxrwx 1 root root 48 Feb  2 18:57 /etc/alternatives/iceweasel-javaplugin.so -> /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so
# mv /etc/alternatives/iceweasel-javaplugin.so /etc/alternatives/iceweasel-javaplugin.so_old
# ln -s /usr/lib/jvm/java-6-sun-1.6.0.26/jre/plugin/i386/ns7 /etc/alternatives/iceweasel-javaplugin.so

Now it works well!

I'm using the same version of java.
Followed this, but it still doesn't work for me

My little brother wants to play java games. Do you have any alternate ideas for what might fix it?

Run the following commands as root:
update-alternatives --config java
update-alternatives --config javac

symlink the Java plugin as root
cd /usr/lib/mozilla/plugins/

Followed by :
ln -s /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so

You could also try using OpenJDK or follow the Howto in my LQ blog and install Oracle's Java.

thanks craigevil

my steps based on your method, which works for wheezy amd64

1. download jre from http://www.oracle.com/technetwork/ja...ads/index.html
2. extract to /opt

# tar -xvf jre-7u5-linux-x64.tar.gz -C /opt/

3. symlink to mozilla plugins folder

# cd /usr/lib/mozilla/plugins/
# ln -s /opt/jre1.7.0_05/lib/amd64/libnpjp2.so

4. restart Iceweasel
