In my Ubuntu 8.04 'Other' menu, it has 'OpenJDK Java 6 Runtime', 'Sun Java 5.0 Runtime' , 'Sun Java 6 Runtime'.
Can you please tell me where are these actually installed? I can only fine 1, the OpenJDK :
$ which java /usr/bin/java
$ java -version java version "1.6.0_0" OpenJDK Runtime Environment (build 1.6.0_0-b11) OpenJDK Server VM (build 1.6.0_0-b11, mixed mode)
How can I find the others?
