Hello. Package Manager reports (with a green checkmark) that I have java-1.6.0 installed on my machine (running Cent 5.3), but it seems to not be running. I used http://java.com/en/download/help/testvm.xml and got "Something is wrong. Java is not working." Perhaps I'm confused on which program I need to use java-coded apps. PM lists this app as "OpenJDK Runtime Environment" - is this it? [mykolas at sr1220 ~]$ rpm -q jdk jre package jdk is not installed package jre is not installed Can someone explain, or provide a link to a particular webpage that would clue me in?
