Running Core 5.
The base install put Java 1.4.2 on there. Too primeval for my needs.
I used this FAQ to install Java JDK 1.5.0, update 9:
This took me through installing the Sun self-extracting package, and installing the Fedora Compatibility Package for Java.
Java is apparently there:
[root@FedoraDell ~]# which java
[root@FedoraDell ~]# ls -l /usr/bin/java
lrwxrwxrwx 1 root root 22 Mar 7 22:17 /usr/bin/java -> /etc/alternatives/java
[root@FedoraDell ~]# ls -l /etc/alternatives/java
lrwxrwxrwx 1 root root 35 May 28 17:59 /etc/alternatives/java -> /usr/lib/jvm/jre-1.5.0-sun/bin/java
[joe@FedoraDell etc]$ ls -l /usr/lib/jvm/jre-1.5.0-sun/bin/java
-rwxr-xr-x 1 root root 64248 Oct 12 2006 /usr/lib/jvm/jre-1.5.0-sun/bin/java
It's going through two links, but it's there!
However, when I try to see if I have the right version installed:
[root@FedoraDell ~]# java --version
Unrecognized option: --version
Could not create the Java virtual machine.
