How to administer JigSaw on a macintosh without JDK1.2 ?

I have successfuly installed and run jigsaw_2_0_4 on a macintosh with 
Mac OS 9.0, Apple MRJ 2.2
(and Swing 1.1.1), but JigAdmin doesn't work as well. In fact it 
starts running and then if I click
on the http-server icon on the left, I got the following  error :

Exception occurred during event dispatching:
java.lang.NoClassDefFoundError: java/awt/dnd/DropTargetListener
	at 
org.w3c.jigadmin.editors.SpaceServerHelper.getTreeBrowser(SpaceServerH 
elper.java:139)
Exception occurred during event dispatching:
java.lang.NoClassDefFoundError: java/awt/dnd/DropTargetListener
	at 
org.w3c.jigadmin.editors.SpaceServerHelper.getTreeBrowser(SpaceServerH 
elper.java:139)

Then the cursor icon in JigAdmin doen't change from the waiting icon, 
and the root icon in the
administration zone doesn't appear...

As stated in the documentation the problem comes from the fact that I 
should use a JDK1.2,
but to my knowledge, this version is not available on the Macintosh 
platform. Thus my question,
is there another way to administer jigsaw on a macintosh ? Is the 
drag and drop feature
of JigAdmin the only reason for using JDK1.2 and is there a work 
around to remove it ?

Another solution could be to run the older version of JigAdmin, but 
does it work with jigsaw 2.0.4,
or should I go back to an older version of jigsaw ?

Thanks,

Stephane
