<\/p>\n

This little guide is just a greatly padded out version of instructions I got from Misha<\/a> but since we have quite a few Ubuntu<\/a> users and quite a few Java programmers in MiNDS&gt;<\/a> this should come in quite useful.<\/p>\n

Basically this is the Debian way of installing the Sun JSDK so that it can be managed with dpkg<\/font> and hence easily upgraded or removed at a later date.<\/p>\n

Firstly, since Ubuntu IS a distribution of Debian<\/a> really I will just refer to Debian in these instructions but the instructions also apply to Ubuntu and in fact it was on Ubuntu that I tested this. Also, these instructions assume that you are logged in as a user who has access to root via sudo<\/font>.<\/p>\n

The way this will work is that we will use a Debian package called java-package<\/font> to turn the binary Linux installer we get from Sun (or IBM and others too) into a proper Debian package (.deb<\/font>) and then we will use Debian’s package manager (dpkg<\/font>) to install that Debian package.<\/p>\n

The first step in the process is to install the java-package<\/font> program that will allow us to create the .deb<\/font> file. To do this simply type:<\/p>\n

sudo apt-get install java-package<\/pre>\n
If you are asked for a password it is for sudo<\/font> and you should enter your own login password.<\/p>\n
The next step is to go to java.sun.com<\/font> and download the Linux binary installer for the JSDK that you want to install. DO NOT DOWNLOAD THE LINUX RPM FILE!<\/p>\n
The next step is to use java-package<\/font> to turn this binary file into a Debian package, to do this move into the folder where you downloaded the binary file from java.sun.com<\/font>. <\/p>\n
NOTE, if you are doing this in the college on your machine for your 4th year project you will have to copy the binary file to \/tmp<\/font> and work from there because local root does not have access to your NFS mounted home directory.<\/i><\/p>\n
For this step you will need fakeroot<\/font>, if you don’t have it installed install it with apt-get<\/font> like so:<\/p>\n
sudo apt-get install fakeroot<\/pre>\n
Once you have fakeroot<\/font> installed and you are in the right directory start the packaging with the command (replacing file_from_sun.bin<\/font> with the actual name of the file you got from Sun):<\/p>\n
fakeroot make-jpkg file_from_sun.bin<\/pre>\n
This will now appear to run the Sun installer but rather than installing it into your system it is extracting it to a temporary fake root file system and then creating the .deb<\/font> file from the files in that fake file system. During this stage you will be asked to agree to the Java license agreement.<\/p>\n
When the above command completes (will take a few minutes) a .deb<\/font> file will have been created in your current folder. This is the file that we will now install with dpkg<\/font> as follows (replacing name_of_deb_file.deb<\/font> with the actual name of the .deb<\/font> file created):<\/p>\n
sudo dpkg -i name_of_deb_file.deb<\/pre>\n
And hey presto you are finished, when ever you want to get rid of that JDK all you have to do is (replacing name_of_deb_file_without_The_extension<\/font> with the name of the generated .deb<\/font> file but with the .deb<\/font> extension left out, e.g. sun-j2sdk1.5<\/font>):<\/p>\n
dpkg --purge name_of_deb_file_without_The_extension<\/pre>\n
You can then install a new JSDK in the same was as described above or just leave your system Java free (heaven knows why you’d do something mad like that!)<\/p>\n
