I agree that, I was just thinking on it this morning because gvSIG also
needs the SUN JRE (1.5 I'm afraid) and it makes sense to have all the
java stuff together (installation, variable setting, etc.), to have
paths controlled.

Anyway it seems the common locations for JRE are:

/usr/lib/jvm/java-6-sun
/usr/lib/jvm/java-1.5.0-sun

that in fact are symlinks to real folders so we should use them, don't we?

Maybe you were thinking on the debian alternatives system so for example
in my machine:

$ ls -l /etc/alternatives/java
[...] /etc/alternatives/java -> /usr/lib/jvm/java-6-sun/jre/bin/java
