is there a Java VM for NV+

Is there another new location for sun-java6-jdk? I made the recommended changes to my /etc/apt/sources.list and get the following error:

NAS_01:~# apt-get install sun-java6-jdk
Reading Package Lists... Done
Building Dependency Tree... Done
Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate
