Just decided to poke around in natty's update-alternatives ...
[joakim@lapetus ~]$ lsb_release -a

[joakim@lapetus ~]$ update-alternatives --list javac
/usr/lib/jvm/java-6-openjdk/bin/javac
/usr/lib/jvm/java-6-sun/bin/javac
It seems that ubuntu separates the running of java and the compiling of java, and doesn't let the update-alternatives use the jdk as the running jvm.
Bummer.
For the record, I don't use the installed by ubuntu JVM's

For that version of jetty (because of the version of jasper, the jsp

a full jdk, not a jre in order to compile your jsps.
