How to install Sun's Java correctly on Debian/Lenny?

Dims · 05-06-2009, 12:58 PM

I see, that my distribution is already contains some JVM, but a free one, not Sun's.

Below is version output.

testbed:/usr/share# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.3.2

Note, that gij package is not installed, not decribed in package.debian.org and gij command is not working:

testbed:/usr/share/java# gij
bash: /usr/bin/gij: No such file or directory

My questions are:

1) What package is responsible for java, shipped with Debian?

2) How to remove shipped java and turn to Sun's one?

When I am running an installer from Sun's site, it just creates a folder for JDK. Is this correct?

1) I think gij is the default java bytecode interpreter installed with gcc. http://packages.debian.org/source/lenny/gcc-defaults

2) You have to have the non-free repositories available, then sudo aptitude install sun-java6-jre (or sun-java6-jdk for the developer tools) if there is a conflicting package, it should say so and ask if you want to uninstall the other one (or at the very least tell you what it is).

after installing the Sun java on Debian, don't forget to configure alternatives, else the default may still point to gij..

update-alternatives --config java

But how? I remember, that I have choose non-free ON while installation. But now I see no sun-java... packages neither in aptitude not in apt-cache search.

How to enable these repositories now?

I found the similiar functionality myself, in galternatives GUI program.

But new questions arose: it looks like alternatives changes only "java" symlink. But this is not only thing, java requires. What about JAVA_HOME variable and etc?

Sorry for my newbie quetions :>

Edit /etc/apt/sources.list and just add non-free to the line

Code:

# See sources.list(5) for more information, especially
     # Remember that you can only use http, ftp or file URIs
     # CDROMs are managed through the apt-cdrom tool.
     deb http://http.us.debian.org/debian stable main contrib non-free
     deb http://security.debian.org stable/updates main contrib non-free

Then run aptitude update (with sudo or root).
