Sun does it just opposite:

root at csw [global]:/usr/jdk > ls -la
total 14
drwxr-xr-x   4 root     bin          512 Aug 18 18:09 .
drwxr-xr-x  39 root     sys         1024 Aug 19 11:29 ..
drwxr-xr-x   3 root     bin          512 Aug 18 17:07 instances
lrwxrwxrwx   1 root     other          7 Aug 18 17:07 j2sdk1.4.2_16 - 
 > ../j2se
lrwxrwxrwx   1 root     other         18 Aug 18 18:09 jdk1.5.0_16 ->  
instances/jdk1.5.0
lrwxrwxrwx   1 root     other         11 Aug 18 18:09 latest ->  
jdk1.5.0_16
drwxr-xr-x   8 root     bin          512 Aug 18 17:19 packages

The files in instances/ and links in jdk/.

Is it really useful to have a just-the-latest-I-don't-care-Java?
I would imagine it would be best to have an apache-like configuration:
The Java software maintainers (e. g. Tomcat) chooses the build jre
and depends on that. The version is now 1.4.2, should that be jdk14 or
jdk142?
James, any advice?


Best regards
