Dunno, got to ask Sun about that :)

IMO yes, but I just tried to download all the 1.4, 1.5 and 1.6 JREs and 
they don't have pkg installers for any of them.

Phil asked if the directory should be "java" and that what what I 
originally wanted too, but Sun uses /usr/java as a symlink to the latest 
java, just like /usr/jdk/latest.

So this is what I want:

/opt/csw/jdk/jdk1.5.0_16
/opt/csw/jdk/instances/jdk1.5.0 -> ../jdk1.5.0_16

/opt/csw/jdk/jdk1.6.0_10
/opt/csw/jdk/instances/jdk1.6.0 -> ../jdk1.5.0_10

And for the JREs:

/opt/csw/jre/jdk1.5.0_16
/opt/csw/jre/instances/jdk1.5.0 -> ../jdk1.5.0_16

/opt/csw/jre/jdk1.6.0_10
/opt/csw/jre/instances/jdk1.6.0 -> ../jdk1.5.0_10

I wouldn't mind having a "latest" symlink too, but then we need a way to 
figure out if a package is "newer" than another (like, if I install 
CSWjdk6 and then CSWjdk5, I don't want the symlink to be overwritten).
