Unable to Sun JDK on Ubuntu 9.10

Hello,

Installed SUN JDK usnig the following command on Ubuntu[ 9.10 Karmic Koala]. It seems already there is a default version(open jdk) but i want to use SUN JDK for Android development.

when i run a simple program i get the following error
# javac HelloWorld.java
The program 'javac' can be found in the following packages:
 * openjdk-6-jdk
 * ecj
 * gcj-4.4-jdk
 * gcj-4.3
 * jikes-classpath
 * jikes-kaffe
 * kaffe
 * sun-java6-jdk
Try: sudo apt-get install <selected package>

I guess the system is getting confused between the sun jdk and open jdk versions ?

I also ran
$sudo update-java-alternatives -s java-6-sun
