Well, yes that is the approach that google revealed.  I think I have 
only downloaded the wrong thing from Sun 3 times so far.  But I have 
tried again, and got a little further this time.  Steps were:

1. As you suggested get the nosrc.rpm from

http://www.jpackage.org/browser/rpm.php?jppversion=1.7&id=7539 

2. rpm -i java-1.6.0-sun-1.6.0.3-1jpp.nosrc.rpm

3. Download jdk-6u3-linux-i586.bin from Sun.  Start at X, select  
Java(TM) SE Development Kit 6 Update 3, get "Linux self-extracting 
file".  Move jdk-6u3-linux-i586.bin to /usr/src/redhat/SOURCES/.

4. rpmbuild -ba /usr/src/redhat/SPECS/java-1.6.0-sun.spec

5. Find finished rpm files in /usr/src/redhat/RPMS/i586.

6. rpm -ivh --test java*.

7. Discover we apparently need /usr/X11R6/bin/mkfontdir, instead of 
/usr/bin/mkfontdir, and also libodbc.so and libodbcinst.so.  Hmm, lucky 
this is the simple way of getting a JRE!

8. Discover detailed discussion of all this at 
http://liquidat.wordpress.com/2007/05/31/howto-sun-java-on-fedora-7/. 

9.  Consider modifying spec files, etc, etc, etc. 

10.  Go back to using Potlatch, and resolve to just nuke all GCJ stuff 
and install the Sun rpm directly.  Tomorrow.

11. Against better judgement, install unixODBC and unixODBC-devel.  Now 
have libodbc.so and libodbsinst.so.

12. rpm -ivh --test java*.  Nope, still fails with libodbc and 
libodbcinst, and mkfontdir.  Now so impressed by how straightforward it 
is to have a JRE on Fedora in the approved way that I need to take a 
good lie down!  ;-)  

And there you have it.  I think my "or" still stands!

cheers
Andrew.
