So I decided to install Java, so I could use Java applets on the net
i don't really understand what u ment by this but u don't need java on u'r machine in order to could use applets on the net because u'r internet browser have one (( it have not really the whole java , but the part to run applets ))
to download java visit [URL=http://www.sun.com] , : download >> java 2 standard edition >> j2se 5.0 >> JDK 5.0 update 4 >>
linux platform ?? Linux RPM in self-extracting file ...... then follow the instalation instructions ..
good luck ,
