Hello,

I am actually working with
ada83 and going forward to 
Ada95. On the way I would
like to do some tests using 
java.

1. Does someone have some good links
   on java->ada83 and java->ada95 or
   some simple demos ?

2. Is it possible to call java FROM ada83 ?
   Can I use JNI ?

3. Is it possible to call java FROM ada95 ?
   Can I use JNI ?

Thank you,

S�bastien.

Maybe Jgnat would be useful? Jgnat compiles Ada source code to Java 
bytecode. You can find it at http://dk.gnuada.org/gnat/jgnat/.

Jgnat's documentation says you can call Java code both from 
bytecode-compiled Ada code and through JNI from native-compiled Ada code.

While I haven't tried interfacing from Ada95 to Java, I have interfaced
between Ada and C, and it is very easy.

Using JNI should be a simple approach.

Last I tried jgnat (not sure when, but years ago), it didn't support
basic Ada features (enumerated types IIRC), was buggy, and hadn't been
updated in years.

If I look at the above URL, it doesn't appear to have been updated
since 2000.

Good idea, IMHO, but I am a bit doubtful of the age of this
implementation.
