Hmm... I actually have it, but how did it get there?

[pd at titmouse2 R]$ /usr/sbin/alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
   1           /usr/lib/jvm/jre-1.4.2-gcj/bin/java
*+ 2           /usr/lib/jvm/jre-1.5.0-sun/bin/java

Enter to keep the current selection[+], or type selection number:
failed to create /var/lib/alternatives/java.new: Permission denied
