Java GUIs and Ada

Java GUIs and Ada

[Nick Almonte]

I'm currently looking to replace an X-windows/Motif GUI coded in Ada
with a Java GUI.  I don't want to rewrite the backgound Ada processing
code, just the GUI.  Is there a way for Java GUI code to call Ada
procedures, and for Ada to pass data for display to a Java GUI?

-Nick

Have a look at jgnat, it's certainly what you're looking for.

You might try AdaJNI from 

   http://www.ainslie-software.com

which allows you to combine compiled Ada code with Java routines.

Alternatively, you could use one of the Ada => Java-byte-code
compilers, either JGNAT from 

   http://www.gnat.com

or AppletMagic from:

   http://www.appletmagic.com
 or
   http://www.aonix.com

Or rethink the entire approach and put on a GtkAda front end...(Unless
you want a PC port soon in which case don't do that since the PC port
of Gtk+ is still fairly weak)

Yes.

You can get a JNI binding at 
http://www.acenet.com.au/~gbull

Another option would be to use JGNAT.

I had two grad students spend some 10wks on the AdaJNI product in a
realistic evaluation. Didn't turn out all that well at that point in time
(beginning of 2000).
I'll point you to the report when I find it ;-)

Whatever the merits of the product AdaJNI, this shouldn't be confused
with the merits of using Ada with Java via JNI.

See http://www.acenet.com.au/~gbull for an Ada JNI binding
(new version will be released when I get time to bundle it up,
probably late June).

I'd be interestd to see this.
