I don't think you needed to update anything. /usr/bin/java points to
/etc/alternatives/java which (probably) points to
/usr/lib/jvm/java-6-sun-1.6.0.20/bin/java, if it doesn't then you
follow the steps. E.g.

First list the java packages installed..
alan at hactar:~$ sudo update-java-alternatives -l
java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk

(I only have one)

Then point java alternatives to it.
alan at hactar:~$ sudo update-java-alternatives -s java-6-openjdk

Doing a direct link from /usr/bin/java to somewhere will work, but
possibly break when a different version of java is installed later.
