Installing Java on Kali-Linux

1. Download the latest Java SE SDK version.

http://www.oracle.com/technetwork/ja...ads/index.html

At the time of writing the filename and version was jdk-7u17-linux-x64.tar.gz

2. Untar the Archive
tar -xzvf /root/jdk-7u17-linux-x64.tar.gz
mv jdk1.7.0_17 /opt
cd /opt/jdk1.7.0_17

3.This step registers the downloaded version of Java as an alternative, and switches it to be used as the default:

update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_17/bin/java 1
update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_17/bin/javac 1
update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_17/jre/lib/amd64/libnpjp2.so 1
update-alternatives --set java /opt/jdk1.7.0_17/bin/java
update-alternatives --set javac /opt/jdk1.7.0_17/bin/javac
update-alternatives --set mozilla-javaplugin.so /opt/jdk1.7.0_17/jre/lib/amd64/libnpjp2.so

4. Test

To check the version of Java you are now running

java -version

To check the browser plugin browse to http://www.java.com/ and click “Do I have Java?”

i think step 3 dosen't work since when i try java -version i get

Code:

---

bash: /usr/bin/java: cannot execute binary file

everything works, just download&install 32 bit version instead of 64 bit.

And in step 3 change /amd64/ to /i386/

In the steps above it is using 64bit software, Dark_4ngel, are you running a 64Bit Kali install or 32?

Not sure but that may be the issue.

Confirmed working.

Is it some major problem to update java after i install it
- after i installed 17 it says update 21 is available and i don't feel like getting burned right now:)

tar -xzvf /root/jdk-7u21-linux-i586.tar.gz

mv jdk1.7.0_21 /opt

cd /opt/jdk1.7.0_21

update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_21/bin/javac 1

update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_21/jre/lib/i386/libnpjp2.so 1

update-alternatives --set java /opt/jdk1.7.0_21/bin/java

update-alternatives --set javac /opt/jdk1.7.0_21/bin/javac

update-alternatives --set mozilla-javaplugin.so /opt/jdk1.7.0_21/jre/lib/i386/libnpjp2.so

This tutorial is for 64 bit and 32bit but it works with some minor changes:

1. Download the latest Java SE SDK version.

At the time of writing the filename and version was jdk-7u21-linux-i586.tar.gz

2. Untar the Archive
tar -xzvf /root/jdk-7u21-linux-i586.tar.gz
mv jdk1.7.0_21 /opt
cd /opt/jdk1.7.0_21

3.This step registers the downloaded version of Java as an alternative, and switches it to be used as the default:

update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_21/bin/java 1
update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_21/bin/javac 1
update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_21/jre/lib/i384/libnpjp2.so 1
update-alternatives --set java /opt/jdk1.7.0_21/bin/java
update-alternatives --set javac /opt/jdk1.7.0_21/bin/javac
update-alternatives --set mozilla-javaplugin.so /opt/jdk1.7.0_21/jre/lib/i386/libnpjp2.so

4. Test

To check the version of Java you are now running

http://java.com/en/download/testjava.jsp

will test later, and give feedback, thanks! :)...

Post post post

Code:

---

sudo apt-get purge openjdk*

---

- I'm not sure that it's a good ideea. By doing that you'll got to handle such:

"The following packages will be REMOVED:
android-sdk* ant* ant-optional* apktool* armitage* bluepot* burpsuite*
ca-certificates-java* casefile* dbpwaudit* default-jdk* default-jre*
default-jre-headless* dex2jar* dirbuster* icedtea-6-jre-cacao*
icedtea-6-jre-jamvm* icedtea-7-jre-cacao* icedtea-7-jre-jamvm* icedtea-netx*
javasnoop* magictree* maltego* metasploit* openjdk-6-jdk* openjdk-6-jre*
openjdk-6-jre-headless* openjdk-6-jre-lib* openjdk-7-jdk* openjdk-7-jre*
openjdk-7-jre-headless* openjdk-7-jre-lib* oscanner* paros* patator*
protos-sip* smali* vega* webscarab* xmind* zaproxy*

The following NEW packages will be installed:
gcj-4.7-base gcj-4.7-jre gcj-4.7-jre-headless gcj-4.7-jre-lib gcj-jre
gcj-jre-headless libgcj-common libgcj13 libgcj13-awt
0 upgraded, 9 newly installed, 41 to remove and 0 not upgraded.
Need to get 24.5 MB of archives.
After this operation, 996 MB disk space will be freed.
"
Think twice before say YES.

Thank you mate. One of the most simple and safest solution. 100% worked out.

It seems like Java breaks for me every time there's a new update or something available. I'm not sure what the deal is. One minute it works, the next minute it doesn't. I always find myself having to come back to this thread, downloading a newer version of Java, and then executing those commands again.

Is there any way I could get some assistance diagnosing this? Pretty annoying to have it stop working all of a sudden.

UPDATED THIS POST FOR versions x86
java version (jdk-7u25-linux-i586)

hurrah its done i have java installed on my kali os

Worked perfectly thanks.

When I type
update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_25/jre/lib/amd64/libnpjp2.so 1
it gives me
update-alternatives: erreur: le chemin alternatif /opt/jdk1.7.0_25/jre/lib/amd64/libnpjp2.so n'existe pas
which means that that pathway doen't exist, can someone help me plz? :/

Thanks a lot, works perfectly with jdk1.7.0_40

I tried this method and succeeded

after the download from the link
http://www.java.com/en/download/index.jsp
#ls
#tar zxvf jre-7u40-linux-x64.tar.gz
#killall -9 /opt/firefox/firefox-bin
#mkdir /opt/java
#update-alternatives --install /usr/bin/java java /opt/java/jre1.7.0_40/bin/java 1
#update-alternatives --set java /opt/java/jre1.7.0_40/bin/java
#ln -sf /opt/java/jre1.7.0_40/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/
#export JAVA_HOME="/opt/java/jre1.7.0_40/bin/java"
#firefox http://java.com/en/download/testjava.jsp

for more information
http://www.backtrack-linux.org/wiki/...p/Java_Install

After downloading the latest version 7.0-40 Java you should change the number 7 in all orders to 40 and Enjoy:o

tar -xzvf /root/jdk-7u40-linux-x64.tar.gz
mv jdk1.7.0_40 /opt
cd /opt/jdk1.7.0_40


update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_40/bin/java 1
update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_40/bin/javac 1
update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_40/jre/lib/amd64/libnpjp2.so 1
update-alternatives --set java /opt/jdk1.7.0_40/bin/java
update-alternatives --set javac /opt/jdk1.7.0_40/bin/javac
update-alternatives --set mozilla-javaplugin.so /opt/jdk1.7.0_40/jre/lib/amd64/libnpjp2.so

The above commands are used for 64-bit Systems:)

Thank you! Followed these steps exactly with 32bit and the newest version of java simply changing the 25 to a 45 and everything worked flawlessly. Much appreciated. :)

Working like described! THX

thxxxxxxxxxxxxxxxxxxxxxxxx

It's Still Work for jdk-7u45-linux-x64.tar.gz thank you Bro.. ;);)

thanks for the guide.
just adding, this is for jdk download, for other download like jre, the folder name and subfolders will be a bit different and you have to adjust yourself.

In case people are still using these instructions, I thought I'd report that I used them to get java working using jdk-7u51-linux-x64.tar.gz. I just changed all the _17 to _51. However, the interesting thing to me was that I got a message saying there was an error. But never the less it all worked.

Why am I approched by this error?

Code:

---

root@kali:/opt/jdk1.7.0_51# update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_51/bin/java 1
update-alternatives: error: alternative path /opt/jdk1.7.0_51/bin/java doesn't exist
