I installed Sun JDK official RPM, from Oracle's site.

I am really not proficient with 'alternatives' command, but I did try to
configure Sun's JDK as the default. The difference is that I configured
javaws as a "slave" to java config, like this:

sudo alternatives --install /usr/bin/java java /usr/java/latest/bin/java
20000 \
--slave /usr/bin/javaws javaws /usr/java/latest/bin/javaws

It seems it worked:

~ ls -l /usr/bin/javaws
lrwxrwxrwx. 1 root root 24 Jun  5 12:25 /usr/bin/javaws ->
/etc/alternatives/javaws

~ file /etc/alternatives/javaws
/etc/alternatives/javaws: symbolic link to `/usr/java/latest/bin/javaws'

/usr/java/latest/bin/javaws is the right executable (I mean, it is Sun's
javaws).

Then make sure that alternatives is set to use what you just installed;

It is, at least AFAICS:

~ alternatives --display java
java - status is auto.
/usr/lib/jvm/jre-1.5.0-gcj/bin/java - priority 1500
 slave jar: (null)
 slave jarsigner: (null)
 slave javadoc: (null)
 slave javaws: (null)
...
/usr/java/latest/bin/java - priority 20000
 slave jar: /usr/java/latest/bin/jar
 slave jarsigner: /usr/java/latest/bin/jarsigner
 slave javadoc: /usr/java/latest/bin/javadoc
 slave javaws: /usr/java/latest/bin/javaws
