Debian: install sun java

Default installation of debian surely give you not the sun java available...

If you give

java -version

something like this is the results....:

 java version "1.5.0"

gij (GNU libgcj) version 4.4.5

[........]

So now we move to install sun java package, and set the java command to the new package installed.....

Please ensure you have into /etc/apt/sources.list file non-free rows for your distribution.

If no(in my case I use squeeze) add the follows:

deb http://ftp.it.debian.org/debian/ squeeze non-free

deb-src http://ftp.it.debian.org/debian/ squeeze non-free

Next

apt-get update

apt-cache search sun-java6

and this result will prompt to you....:

.....

sun-java6-bin - Sun Java(TM) Runtime Environment (JRE) 6 (architecture dependent files)

sun-java6-demo - Sun Java(TM) Development Kit (JDK) 6 demos and examples

sun-java6-fonts - Lucida TrueType fonts (from the Sun JRE)

sun-java6-javadb - Java(TM) DB, Sun Microsystems' distribution of Apache Derby

sun-java6-jdk - Sun Java(TM) Development Kit (JDK) 6

sun-java6-jre - Sun Java(TM) Runtime Environment (JRE) 6 (architecture independent files)

sun-java6-plugin - The Java(TM) Plug-in, Java SE 6

sun-java6-source - Sun Java(TM) Development Kit (JDK) 6 source files

....

So give the follow:

apt-get install sun-java6-jdk

if you are a developer, and you need the jdk....

Or the jre if you want only the runtime enviroment...

apt-get install sun-java6-jre

At the end of installation give this last command

update-java-alternatives -s java-6-sun

to set to java command the right(and new) path....

Run 

java -version 

to look this...:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
[...]

Bye....
