Why can't I select the Sun Java VM ?

# alternatives --config java
There are 2 programs which provide 'java'.
Selection Command
-----------------------------------------------
* 1 /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
+ 2 /usr/lib/jvm/jre-1.5.0-gcj/bin/java
So it thinks I have 2 versions of Java.
Here is the first:
# java -version
java version "1.6.0_0"
IcedTea6 1.4 (6b12-Fedora-10) Runtime Environment (build 1.6.0_0-b12)
OpenJDK Server VM (build 10.0-b19, mixed mode)
Here is the second:
# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.3.2 20081105 (Red Hat 4.3.2-7)
However, I actually have 3 versions of Java, because I installed the Sun
Java from a Sun rpm:
# rpm -ql jre
/usr/java/jre1.5.0_15/CHANGES
/usr/java/jre1.5.0_15/COPYRIGHT
/usr/java/jre1.5.0_15/LICENSE
/usr/java/jre1.5.0_15/README
/usr/java/jre1.5.0_15/THIRDPARTYLICENSEREADME.txt
/usr/java/jre1.5.0_15/Welcome.html
/usr/java/jre1.5.0_15/bin
/usr/java/jre1.5.0_15/bin/ControlPanel
/usr/java/jre1.5.0_15/bin/java
If I test it it works fine.
# /usr/java/jre1.5.0_15/bin/java -version
java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Server VM (build 1.5.0_15-b04, mixed mode)
So I move it to /usr/lib/jvm and run again:
alternatives --config java
There are 2 programs which provide 'java'.
Selection Command
-----------------------------------------------
*+ 1 /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
2 /usr/lib/jvm/jre-1.5.0-gcj/bin/java
The Sun Java doesn't show up.
/usr/lib/jvm looks like this:
ls -al

lrwxrwxrwx 1 root root 29 jre-openjdk
-> /etc/alternatives/jre_openjdk
How do I get the Sun java to be the default Java, without doing a 24
step build that Googling finds ?
Thanks
