Subject: installing java on Linux
When you query or uninstall an installed package, don't include the '.rpm'.
Ex.
`rpm -ivh j2sdk-1.4.1_01-fcs.rpm` installs java.
`rpm -q emacs` tells me 'j2sdk-1.4.1_01-fcs' is installed.
`rpm -e j2sdk` uninstalls java.


You can also query an rpm file that isn't installed.
Ex.
`rpm -qpi j2sdk-1.4.1_01-fcs.rpm` gives me a description of the package.


I used the j2sdk-1_4_1_01-linux-i586.bin package from Sun. It installed all
the files in /usr/local/j2sdk1.4.1_01. Then I had to place
'/usr/local/j2sdk1.4.1_01/bin' on my path.
