Debian Wheezy and Java Plugin

[fabriciopj]

Hi all,

I have installed, via apt-get, the JDK 7, as you can see below:

Code: Select all

fabricio@debian7:~$ java -version
java version "1.6.0_27"
OpenJDK Runtime Environment (IcedTea6 1.12.5) (6b27-1.12.5-1)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

But i cannot make the Java Plugin work on my Iceweasel. I read in some foruns that i should create a simbolyc link from the file "libnpjp2.so" to "$HOME/.mozilla/plugins", but i cannot find the lib "libnpjp2.so".

What can i do to solve this issue?

Thanks in advance.

It seems to me you have jdk 6, not 7.
This is JDK 7:

Code: Select all

mor@debian:~$ java -version
java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-5)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
mor@debian:~$ 

Anyway, did you install the icedtea-6-plugin (for JDK6) package?

If you want jdk 7 instead, install icedtea-7-plugin and apt will install all that is needed.
You can eventually purge the 6 stuff, if you want or care.

This is the way I did it :-

Code: Select all

$ sudo aptitude install icedtea-7-plugin=1.4-3 icedtea-netx=1.4-3 icedtea-netx-common=1.4-3 -y

Once I did that I just had a look inside the icedtea-7-plugin :-

Code: Select all

$ dpkg -L icedtea-7-plugin
/.
/usr
/usr/lib
/usr/lib/jvm
/usr/lib/jvm/java-7-openjdk-amd64
/usr/lib/jvm/java-7-openjdk-amd64/jre
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
/usr/lib/mozilla
/usr/lib/mozilla/plugins
/usr/share
/usr/share/doc
/usr/share/doc/icedtea-7-plugin
/usr/share/doc/icedtea-7-plugin/copyright
/usr/share/doc/icedtea-7-plugin/changelog.Debian.gz
/usr/share/icedtea-web

Then go to /usr/lib/mozilla/plugins and see if everything is right there :-

Code: Select all

/usr/lib/mozilla/plugins$ ll libjavaplugin.so 
lrwxrwxrwx 1 root root 39 Aug  6 20:12 libjavaplugin.so -> /etc/alternatives/mozilla-javaplugin.so

As everything checked out, the last thing to do was open the browser and go to Tools > Addons and see if in the plugins tab it says something and for sure it says :-

Code: Select all

IcedTea-Web Plugin (using IcedTea-Web1.4 (1.4-3))
The IcedTea-Web Plugin executes Java applets [u]More[/u]

And then lastly, go to https://www.java.com/en/download/testjava.jsp and check that the icedtea7 webplugin logo is displayed.
