Although technically not a comparison of features (I'll leave
that to Mr. Brosgol and others), those interested in writing
Ada applets with Aonix ObjectAda might find the following
article and web site useful as a starting point:

Westley, T., "Writing Java Applets in Ada: A Beginner's Guide,"
Ada User Journal, Vol. 19, Num. 1, April 1998.

http://www.buffnet.net/~westley/AdaJava/

If you have an applet you'd like to contribute to this site,
let me know.  It should demonstrate how to code one or two
features useful for building dynamic web sites.
