Compile of jhandles is now working.  Again I hacked the Makefile 
directly rather than dealing with autoconf immediately.

 HAVE_JAVA=yes
 JAVAC=javac
 JAR=jar
 JOGL_JAR=$(HOME)/Library/Java/Extensions/jogl.jar
 OCTAVE_JAR=$(HOME)/octave/java/octave.jar
 OCTAVE_PATHSEP=:

I put jogl and its associated jnilib files in ~/Library/Java/Extensions 
in hopes that I won't have to set DYLD_LIBRARY_PATH to point to them.

Running the example you gave earlier:

 page_screen_output(0); % do not buffer output
 h = uicontrol('string', 'OK'); % should create a push button
 set(h, 'callback', @(h,e) disp('button clicked')); % add a callback to 
the button
 uicontrol('style', 'edit', 'min', 0, 'max', 2, 'position', [10 45 200 
300], ...
'horizontalalignment', 'left', 'backgroundcolor', 'w'); % should create 
a text edit area

I get
 [Java CocoaComponent compatibility mode]: Enabled
 [Java CocoaComponent compatibility mode]: Setting timeout for SWT to 
0.100000
 h=-1

At this point the java client hangs, and nothing is displayed.
