ADA & JAVA.How to communicate?

ADA & JAVA.How to communicate?

[romain fortunato]

HI all.


we have the following problem:


-on one part we have a simulation program written in ADA83.
-on the other part a JAVA interface distributed on www.

ANd we want to make the two communicate quickly.

Communication through pipes is impossible due to java.

so:

-Is it possible to implement sockets in ADA(which version)?
-does anybody knows how to specify a java native method to be written in
ADA?


thx to all

Yes, it is certainly possible to use sockets from Ada.
Just use pragma Interface/Import to the appropriate system call.

Java native methods are implemented using shared libraries/DLLs.
If you can call Ada from C, then you can call Ada from Java.  Just
make your Ada code have the interface expected of a C routine
implementing the Java Native Interface.  

You might try contacting Ainslie Software.  They have a very
nice binding tool for Ada 95.  They might be able to give you
more information on how to create a Java-callable Ada 83 routine,
based on their experience creating AdaJNI.  Their web site is:

The relevant e-mail address is probably:

Sure.  Claw (among others) does it in Ada 95 for at least
Apex, Gnat, Janus, and ObjectAda under MS Windows.
Take a look at www.adapower.com for links.
