machine can provide the same functionality. Why should I have to learn
another language? I can see the necessity to learn XML; however, many of us,
myself included, are NOT full-time programmers. Ada was created to minimize
the number of languages one has to learn.
[Bob Leif] How does one make an Ada J code compiler call an Ada exe?
[Pascal Obry] I don't understand the question !
Internet devices are presently perceived as a large market. The GUI of these
devices should be based on web pages that could use Ada compiled to J code.
For reasons of efficiency, it would be very useful to have the Ada J code
capable of being interfaced to compiled Ada code. Another example, someone
in the Ada community decides to get rich and make a competitor to Microsoft
Office or Works. They create standard Ada executables that contain COM
objects etc. However, the application needs a scripting or macro language. I
prefer an Ada J code compiler to Visual BASIC. The scripting language will
need to call Ada executables.

Again, I don't think that Ada scripting language is a good idea ! Ok let me
explain :) With current scripting language like ASP, PHP you embed the code
into the Web page and this is (from my point of view) as bad as putting the
Web page into a CGI program !
Ok, now we need some scripting for -small- interaction with the Web page.

Right, and this is not likely to happen...
How do I develop Web servers today:
I use a template parser (see my contribution page) to fill the data into an
HTML template page. In the HTML-template page there some special tags that
replaced by the template parser. This has proved to be fine. I have some
guys working on the design of the site and some others who wrote the
(access to the database, compute the values...). The clean separation
design and code make it easy to do maintenance of the code (you can't break
the design) and to change the design (you can't break the code) and this is
very often done by differents peoples...
Now, what could be the right solution tomorow:
When XML/XSL and such are ready (right now support by browsers is very poor)
would be nice to have the data put into an XML file, the transformation into
the XSL part and use a piece of code to merge both and create an HTML page
use AWS (shameless plug :) to avoid the CGI overhead ! And of course
Just my 2 cents,
