It looks like you have javac already installed. If you execute

$ which javac

Does it show you the installation path?

I've found java 7 to be better. Have you tried using that version?

username$ which javac
username$
it doesn't give me any output

but with " $ locate javac " i can see a path " /usr/lib/jvm/java-6-openjdk/bin/javac "

-

i tried
sudo apt-get openjdk-7-jdk
yesterday with the same results

not sure if there is a better solution

but i made manually a javac link at "/usr/bin/" dir and it fixed my problem


username~$ sudo ln -s /usr/lib/jvm/java-6-openjdk/bin/javac /usr/bin/javac


thnx for the reply @doobrie, and my friend MITSARAS !

KOSEOS!

For some reason you have the compiler installed, but it wasn't in your path (hence making the link worked).

Making the link is a good solution.
