You can get the SDK (devel kit) of the JSE (standard edition) of Java. You can alternatively get the JRE (runtime edition I think?) of the JSE.

Try:

http://java.sun.com
http://java.sun.com/j2se/1.4/download.html

Hope that helps, at least a little. :)

Some simple definitions -

JDK - Java Development Kit.
SDK - Software Development Kit, usually used in conjuntion with the word Java, e.g. "Java SDK"
JRE - Java Runtime Environment.
SE - Standard Edition; what you usually run on the desktop and sometimes on the server.
EE - Enterprise Edition, standard edition plus some more enterprise features.

If you just want to run Java program, get the JRE. If you want to develop java programs, get the JDK, which is JRE plus developmental tools.

SDK just means Software Development kit, whether it is Java SDK or Windows SDK.

JDK (Java Development Kit) == Java SDK.

Just download the JDK 1.4 and you should be fine. It may also be called Java SDK 1.4, etc...

Unless you need the Enterprise features, you don't need the EE (enterprise edition).

[root@localhost Software]# ./j2sdk-1_4_0-forte_ce-4-bin-linux.bin*

...Error writing file = There may not be enough temporary disk space. Try using -is:tempdir to use a temporary directory on a partition with more disk space.

I did df -k and got

[root@localhost Software]# df -k

/dev/hda6 1153332 239640 913692 21% /home

How could I use /dev/hda6 partion now?

Your / partition is almost full, which explains the error.

Try freeing up some diskspace. You shouldn't install it under /home.

Try freeing the partition and install JDK1.4 on the server. JRE is meant for runtime environment of Java.
