Backtrack 5-Java Plugin Firefox 4.0.1 x64

**Haleema** · 25-06-2011

I tried several routes to try Firefox GNOME 4.0.1 in Backtrack 5 x64 to get a working Java plugin for the job. I wanted to see if anyone had tried anything. I had tried following things.
* Apt-get install icedtea6-plugin. Gave this a try, and tried to copy the usr/lib/jvm/java-6-openjdk/jre/lib/amd64/IcedTeaPlugin.so / some other areas (/ usr / lib / mozilla / plugins, / root / . mozilla / plugins) and FF no longer recognized.
* You tried the official Ubuntu guide: Java plugin https://help.ubuntu.com/community/AM...it
* Tried to download official copies http://www.java.com/en/download/manual.jsp Sun Java and install them. He tried 64-bit (no browser plugin, so no), and 32-bit versions.But nothing is working. Can anyone help me to sort out this issue?

I don’t think it is backtrack 5 kde 64 bit problem .I’m also not sure why it work in backtrack 5 gnome 64. I like you to go to java website and check why you’re not able to download the java plugins.Dont forget to go to java official website and also try to find out on firefox website .there must be solution for your query .I think after going through these website you will surely find the reason and you will be able to install java plugin.

I thought the success of the file download 32-bit self extracting the Sun Java website, installing and creating symbolic links. The reason 32-bit because we're still a 32-bit browser in a 64-bit operating system. Finally u figured out your actual problem. So download firefox x64 and then try to install java plugin and I’m sure you will be successfully able to install java plugin .Whenever you’re using 64 bit operating system ,always 64 bit software otherwise it will not work properly.

I downloaded: Linux (self-extracting file) filesize: 20.6 MB from http://www.java.com/en/download/manual.jsp

Code:

chmod +x jre-6u26-linux-i586.bin
./jre-6u26-linux-i586.bin
cd jre1.6.0_26
cd plugin
cd i386
cd ns7
cp libjavaplugin_oji.so /root/.mozilla/plugins
firefox

java is not listed in the extensions list. kill firefox

Code:

cd ..
cd ns7-gcc29
cp libjavaplugin_oji.so /root/.mozilla/plugins
firefox

I couldn't find the original link but this is what I did to get the Java plugin working.

Code:

mkdir /root/Downloads
Downloaded the latest java http://www.java.com/en/download/manual.jsp self-extracting file
Code:
mkdir /opt/java
cd /opt/java
sh /root/Download/<filename.bin>
update-alternatives –install “/usr/bin/java” “java” “/opt/java/jre1.6.0_21/bin/java” 1
update-alternatives  --set /opt/java/jre1.6.0_21/bin/java
ln –s /opt/java/jre1.6.0_21/lib/i386/libnpjp2.so /usr/lib/Mozilla/plugins/
export JAVA_HOME=”/opt/java/jre1.6.0_21/bin/java”
java –version

Now plugin will work in firefox x64
