update-alternatives: using /usr/lib/jvm/jdk1.7.0_02/bin/javac to provide
/usr/bin/javac (javac) in auto mode.
but when i tried javac command it gives following error
bash: /usr/bin/javac: Permission denied
so i remove it using
root@S13:/home/nika/Downloads# update-alternatives --remove-all javac
can i get some help?
I would be of better help if my other harddrive, with ALL of my
accumlated links weren't in repose on that dead parrot. So, just google
on "install java 7 linux ubuntu" and you'll find some good links to show
you exactly how. They will provide a script that will make all of the
links for you in alternatives, so that every possible java binary is
found and updated for you. It's worth it, as java 7 seems to be much
more multi-core aware.
Huh, I just googled and it seems someone has a ppa
that provides an app that downloads and installs Oracle Java 7 for you
and installs it. This would beat doing by hand like I had to. Give that
a whirl! Otherwise I found the site I used before:
I'd try the ppa first. Enjoy! Hope this helps. IMHO, Java 7 is the way
