I have gotten the alternatives mess straightened out.  I have
Sun's JDK 1.5.0_20 & 1.6.0_16 installed and working correctly.
I have tested each of the `java/c -version',  switching using
galternatives and `java/c -version' correctly reports the
correct version each time.

Now, I have verified that regardless of which Java version one is
using, it does not fix  the problem with Ganymede. I have tried
all 4 versions of java (two to Fedora's gcj/open, and the other
two:  Sun's 1.5.0_20 & 1.6.0_16) and both Fedora-11-Eclipse &
Galileo works fine.  Just not Ganymede, and the problem may
be that of what Andrew Overholt has said:

"... he was bitten by the fact that the XULRunner APIs changed
post-Eclipse 3.4 (Ganymede)"

I don't know what Andrew means by: "post-Eclipse 3.4 (Ganymede)",
but I assume he means Eclipse's Ganymede SR-2 release, if so,
that is not working, at least for me.

But here is the thing, Ganymede SR-2 works on F9, can't say for sure
about F10, but does not on F11.  So I am not sure when between
these Fedora versions: "XULRunner APIs [has] changed". ;)
