I have added a new Java program on my homepage for OS/2-eCS. Its called Geometria and you can find more on my page:
http://joopn.home.xs4all.nl/os2ecs/ecs6e69.htm.
The message in software news of an updated Geometria version 4.0 on Monday, 13 June 2016 is not an update of version 3.2 but a total new approach. What Windows and Linux users get, and eComStation users don't, is a tiny web server that runs on your desktop with a simple double-click. This is the rest of the answer of the developer of Geometria;
I would suggest to connect your eComStation computers to a PHP-enabled web server, such as Apache. The server does not need to be eComStation, it can be a Linux server. If that is not possible, perhaps this site <http://www.amp4ecs.de/> can be of help. However, if you do find a way to connect your people to a web server, please proceed as follows:
* Download the server package from
http://geocentral.net/geometria/download * Unzip and copy to the web server's web documents directory.
* Connect your user computers to
http://your.server.name/geometria/index.htmlYour users will be able to do everything except save problems and solutions back to the server. However, there is a way to let them do that: change readOnly from true to false in the geometria.php file. The application running on the official Geometria web site is just Apache+PHP with readOnly=true. If you do decide to let your users save their work back to the server, I would advise to have a separate folder under the root 'all' node in the document navigator, for each user. If the number of the users is large, you may want to consider other options, which will require some work on the geometria.php file.
So there is a way out, but I read it not as easy and certainly not stand alone. May be I'm wrong, but the way you can run version 3.2 is definite totally different then for version 4.0.
Have fun!
