Announcement
------------
Ada-Belgium will hold its 12th annual General Assembly on Monday,
April 11, 2005, at the U.L.B., Department of Computer Science,
Boulevard du Triomphe / Triomflaan, B-1050 Brussels, at 19:00.
The official convocation is distributed separately to members and
is also available on the Ada-Belgium web-server.

There will be refreshments and pizza for Ada-Belgium members at 18:15.
Please notify us if you are a current or new member and intend to
participate at this informal "pre-meeting".

At 20:00 the General Assembly will be followed by a short product
announcement of an "Eclipse plug-in for Ada (ObjectAda or GNAT)",
by Patricia Langle from Aonix France, and at 20:15 by a technical
presentation on "Web-enabling Ada Applications with AWS", by
Jean-Pierre Rosen from AdaLog, France.

20:00-20:15 - Eclipse plug-in for Ada (ObjectAda or GNAT)
---------------------------------------------------------
Speaker
Patricia Langle, Aonix France

20:15-21:45 - Web-enabling Ada Applications with AWS
----------------------------------------------------
Abstract

This presentation describes AWS, the Ada Web Server, and how to use it
for the development of web applications. It describes the principles
of AWS, from the most basic functionalities to the more advanced ones
(Authentication, SOAP interface, session management, hotplugs,
multi-server applications, etc.) The talk emphasizes practical usage
of AWS, and presents design patterns that have proved effective for
developing existing applications. It compares the development process
with AWS to other techniques.  The presentation provides attendees with
the information needed to assess whether AWS is appropriate to their
needs, and the necessary knowledge to start writing full-scale Web
applications.  Attendees should have some knowledge of Ada
programming.  No previous knowledge of Web programming or HTML is
required.

AWS is a free (GMGPL) software component written by Pascal Obry and
Dmitriy Anisimkov that allows developing Web applications in Ada.
Unlike other methods that require a dedicated server (like Apache),
AWS provides services to develop applications that act as autonomous
Web servers, using the Ada language for the semantic part of the
application instead of scripting languages like Perl or Python. This
allows AWS to be used for regular Web servers as well as for writing
applications that offer a Web interface to control more traditional
processing functions. AWS is a mature product that has been used in
many professional applications.

Speaker

J-P. Rosen graduated from ENST (Ecole Nationale Sup�rieure des
T�l�communications) in 1975, and obtained PhD in 1986.  He started as a
software engineer at the computing centre of ENST.  After a Sabbatical
at New York University on the Ada/ED Project, he worked as Professor at
ENST, where he was responsible for the teaching of Operating Systems,
Software Engineering, Compilation and Ada. He created ENST's master's
degree in Software Engineering. He has now formed Adalog, a company
specialized in high level training, consultancy, and software
development in the fields of Ada, OOD, and associated technologies.

J-P. Rosen has written "HOOD: an Industrial Approach for Software
Design", the tutorial book for the HOOD 4 method. This was undertaken
on behalf and under control of the HOOD User Group. This book is
currently the only official tutorial book for the HOOD method; details
can be obtained from http://www.adalog.fr/hoodbook.htm  Other book
publications by J-P. Rosen include the translation in French of Booch's
"Software Engineering with Ada", and a book called "M�thodes de G�nie
Logiciel avec Ada 95" (Software Engineering Methods with Ada 95). He

I keep hearing about this Eclipse IDE. They chant excellences, at least 
for its original Java usage. Does anyone know what would be the extent 
of such a plug-in? Could it eventually be an alternative to GPS?

Kind regards,

Alex.

I know several developers that love it for Java and C++. Several vendors 
are also embracing it as the base framework for hosting their tools 
(e.g. Wind River's new tool suite is eclipse based).

It clearly is an alternative to GPS (not saying it is a better or worse 
alternative...but it is one). It does not "appear" to be open source. It 
certainly is not freely downloadable last time I checked.

If you are willing to give up on free then I think that IBM Ada 
Developer (Rational Apex family) is still a pretty compelling 
environment as well (as an alternative to GPS)

This has changed or something (I had the idea it has always been open 
source), since I already downloaded and installed it some time ago, but 
then I never did any development with it. I've just launched it off and 
there's no restrictions apparently.

See:

http://www.eclipse.org/eclipse/faq/eclipse-faq.html#about_8

Though I've been looking for a source package in the downloads section 
and I don't see it. Maybe it's included in the installable package.

Not the case here. Until very recently I used almost exclusively a vi 
clone. Now I use GPS too, but I'm used to not having much bells and 
whistles.

Though I'm excited about using a leading IDE platform. One of the things 
about Ada is that you feel sometimes isolated, since you use tools 
nobody else uses. I'm curious about having something else in common with 
other OSS developers, if the language can't be.

Eclipse is open source but a plug-in is needed for each new language. 
There is a "Free" C++ plugin. Aonix has written an Ada one but it does 
not (appear) to be freely available. Note that a full Eclipse language 
plug in is non trivial because it is capable of doing more than just an 
editor that calls a compiler.

So are you saying you have previously downloaded the Aonix Ada Eclipse 
plugin or  just Exclipse in general?

Eclipse in general, sorry for the ambiguity. I thought all the time you 
was talking about eclipse the framework and not the Ada plugin.

My interest in any Ada plugin for eclipse is effectively because the 
non-triviality you mention. Since eclipse can do so many things, it's 
apparent that the plugin needs to be quite a beast.
