now my problem is I can't get java installed even under root.
it's sun java J2SE50
jre-1_5_0-linuxi586.bin

the icon has a SH on it, doubleclicking it produces a popup saying the following:

CAN NOT OPEN jre-1_5_0-linux-i586.bin

The filename "jre-1_5_0-linux-i586.bin" indicates that this file is of type "Unknown type". The contents of the file indicate that the file is of type "(null)". If you open this file, the file might present a security risk to your system.

Do not open the file unless you created the file yourself, or received the file from a trusted source. To open the file, rename the file to the correct extension for "(null)", then open the file normally. Alternatively, use the Open With menu to choose a specific application for the file.
and
in a terminal under su I get permission denied.

Sure it's not corrupted? Check the file size.

Instructions here (http://java.sun.com/products/archive/j2se/1.3.0/jre/install-linux.html) in case you ain't seen 'em. ;)

Cheers
Mick

edit: Yes you do need to ./ to run it, sorry. :)

I found I had to make the file executable. Then run as user which creates an rpm file which you probably need to execute as su.

chmod +x filenamehere

or "sh jre-1_5_0-linuxi586.bin" will prolly get it without chmoding it.
