Here are the official directions from SUN:

I don't know why, but the web page You gave me was sending me somewhere else, so I found "j2sdk-1_4_2_05-linux-i586.bin". Downloaded and installed with Your tips it seems to work fine... no errors on the installation! What is the difference between the "j2sdk" and the "j2rd"?
Thanks.

I never heared from j2rd, only j(2)re.

The second is the java-runtime-environment, to run java-programs.
The first is the java-software-development-kit, to develop java-programs.

If you have the sdk, a jre is included already.
Adding JAVA_HOME to your user-environments in /etc/profile is recommendet if you develop java-programs, i.e:

export JAVA_HOME=/opt/j2sdk

i am sorry "RE" not "RD"! I will try that as soon as I can. Thanks

[xaviers2002]

"export JAVA_HOME=/opt/j2sdk"

Do I have to run this from root or command?
Nothing has happened form root.
Thanks

gah silly SUN makes it hard to link to their downloads. Commercialism at its finest I tell you!

you DO need j2re!

Try this link:
http://java.sun.com/j2se/1.4.2/download.html

Scroll down to where you see this:

Download J2SE JRE

When you click that link you will be taken to a licensing agreement. Hit "accept" and "continue".

Download this:

ok done!!! thanks
Is there a common way of installing programs on debian or every program is different?
Thank You again.
Also what is the difference between the begginer installation and the debian like...?

Java is a proprietary software from SUN. It is not OSS (Open Source Software) like Debian GNU Linux. Debian uses dpkg to install packages. The easiest way to use dpkg is apt-get which is a frontend for dpkg. *most* packages are already in Debian and only require a simple command:

apt-get install cdcd

for example. If an application does not exist in the Debian archives you may search here: http://www.apt-get.org/ and perhaps someone has made unofficial packages for Debian. Otherwise you would use source code to compile and install software.

Also what is the difference between the begginer installation and the debian like...?

As I understand it the beginner is most like booting from cd. I think there are several forum postings on that topic already. "Debian like" would be a not so standard Debian installation (but still Debian none the less). Debian is notoriously difficult to install for a beginner. Even the current installer is quite unattractive and yet I have to say that IMHO installing Debian w/ either boot flopies or a small cd image is the best. You simply install the base system and build it from there. As you use Debian more you will come to understand its ways.

[xaviers2002]

If I got it right the "normal" way to install a progrtam on Debian is: open a root shell, type "dpkg apt-get install" followed by the name of the of the program that was downloaded. Correct?

Thanks
