Hi

I installed the JDK-1.6u16 in my F-11, and I used the following commands:
alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_16/bin/java 2
alternatives --install /usr/bin/javac javac 
/usr/java/jdk1.6.0_16/bin/javac 2
alternatives --config java
alternatives --config javac

It seems that you are forgetting the 'config' part of 'alternatives'.

I use this CentOS wiki as reference:
