Java RunTime Environment was not found

[Coletta "Rémi" <remi.coletta@free.fr>]

Hello,

  I have download "j2re-1_3_1_01-linux-i386.bin" and 
"j2sdk-1_3_1_01-linux-i386.bin" and installed it.
  I add in my environnement:
PATH=[..]:/usr/local/jdk1.3/bin:/usr/local/jre1.3/bin:.

But when i try to install StarOffice:
  -> No Java Runtime environnement installed
When i try to install Oracle:
  -> The Java RunTime Environment was not found at bin/jre. Hence, 
the Oracle Universal Installer cannot be run.

What missing ?

PS: excuse for my so bad english
