How do I comm. between Ada & a Java MMI?

How do I comm. between Ada & a Java MMI?

[jesper.andersson]

Hi!

I have the following problem:

I want to communicate between an Ada95 system and a Java GUI.

I can't find any reliable, commersial bindings between these languages.

Does anyone know of a solution?

Take a look at "http://www.appletmagic.com".  This describes
an Ada95 -> Java byte code compiler, which gives you full interoperability
between Ada95 and Java code.

The alternative is to use the Java Native Interface (JNI) which is
based on a relatively simple C interface allowing interaction
between C and Java.  Ada 95 provides a standard way to call C
interfaces, via pragma Import.

See above.

Although it dosn't match your commercial requirement (and may not match
your reliable requirement either!), we did some work along those lines
in our ADEPT project (http://www.cs.tamu.edu/research/ADEPT/).  Perhaps
you may at least get some potential ideas about how it can be done from 
the web information.

Here's an excert from the page:
    Recent work on ADEPT, named ADEPT/JxA, has added the capability of 
    Ada-Java interoperability by allowing Java clients to access Ada 
    servers. This is accomplished with the requirement that each component 
    (client and server), use their respective distributed object models. 
    For instance, Java clients use Java Remote Method Invocation (RMI) 
    to call distributed remote objects that have been created using Annex 
    E in an Ada server. The use of Ada and Java in these roles may provide 
    the basis for solving many of the distributed application problems of 
    the future. The ADEPT/JxA enhancements were also funded by Computer 
    Sciences Corporation. A live demonstration of ADEPT/JxA capabilities 
    was presented at the 1997 Software Technology Conference in SLC Utah, 
    April 28th to 30th. 


In other news, a certain Ph.D. student (me!) who worked on the project may  
be looking for an Ada job in the near future if he doesn't land an academic
one and he'd like to hear about companies doing work along the above lines!
