Install Java on Debian

Step 1: Get the Latest Sun JVM for Debian Linux Platform. Click here 

Step 2: Installing Java on Debian is an easy task, there is a package that can do all the hard task for you. The package is “java-package” which can be installed with:

“apt-get -u install java-package”

Ensure the repository is up to date before installing this package, as you might encounter some problems.

Step 3: Here you create the “.deb” package from the file. You have to be a non-root user to perform this step. Create a temporary directory and copy the java file “.bin” into it. Enter the following command:

“Newroot make-jpkg jdk-1_5_0-linux-i586.bin”

You can Change the name of the Java “.bin” if you have to.

Now you can install the package as a root, if successful it should show:

The Debian package has been created in the current directory. Youcan install the package as root (e.g. dpkg -i sun-j2sdk1.5_1.5.0+update00_i386.deb).

Step 4: You have to be root to issues the command here, so if you’re not root, switch over to root. 

“dpkg -i sun-j2sdk1.5_1.5.0+update00_i386.deb”

If this is not the name of your package you can specify another one, you should get the name from the previous success message.

“java -version”
