Debian 4 Sarge
To find out which version is installed, just open up a command line and type java -version in there.
Installing the Sun J2SE on Debian Sarge
First, open a Shell window:
su <Your root password> cd ../../etc/apt nano -w sources.list
Add:
contrib non-free
To the last three lines, example of finished file:
#deb file://cdrom/ sarge main
deb http://ftp.uk.debian.org/debian/ stable main contrib non-free deb-scr http://ftp.uk.debian.org/debian/ stable main contrib non-free
deb http://security.debian.org/ stable/updates main contrib non-free
Use CTRL+O to write the changes
Back in the Shell window:
apt-get update
Now that all this is done, your system is ready to install Java. Grab the non rpm Linux self extracting file from http://java.sun.com/j2se/1.5.0/download.jsp (currently jre-1_5_0_04-linux-i586.bin). Just save it to your /home/<user> directory.
Back in the Shell console:
apt-get install java-package
Once installed:
exit cd ../../home/<user> fakeroot make-jpkg jre-1_5_0_04-linux-i586.bin
This may take some time... Once done:
su <Your root password> dpkg -i sun-j2re1.5_1.5.0+update04_i386.deb
Again, could take a while... finally, once done:
chown -R root:root /usr/java/jre1.5.0_02/ ln -s /usr/java/jre1.5.0_02/bin/java /usr/bin/java ln -s /usr/java/jre1.5.0_02/bin/java_vm /usr/bin/java_vm cp /etc/bash.bashrc /etc/bash.bashrc_backup
vim /etc/bash.bashrc
Use your favorite editor to add the following lines at the end:
JAVA_HOME=/usr/java/jre1.5.0_02 export JAVA_HOME PATH=$PATH:$JAVA_HOME/bin export PATH
Check all went well with:
java -version
Done? Good!
