update the database for mlocate:

$ sudo apt-get updatedb

Then check again:

$ apt-cache policy update-sun-jre
update-sun-jre:
  Installed: 1.1.3
  Candidate: 1.1.3
  Version table:

$ sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).

BTW: unless you are sure that your "program that requires (Oricle) Sun
Java" can use the still unreleased Java 7, I'd recommend you stick with 6.
