Hi Javier,
I have seen all the getting started an I was wondering if this platform will be, in the short run, like tha Outsystem platform? this is in the aspect of drag and drop possibilities to create a full platform/application.
Thanks

No. There are hundreds of drag & drop development platforms, the world does not need one more, I think. Drag & drop were populars in the 90s, think in Visual Basic or Delphi. Even in the Java world the first IDEs I used (in the 90s), JBuilder and Visual Age, were drag & drop oriented. Indeed, one of the first Java specification, JavaBeans (don't confuse with EJB), was to support drag & drop component compatibles for all IDEs. But Java abandonded that tendency soon.
OpenXava is a different thing. Drag & drop is easy to learn, yes, but it's very laborius, because if you have to develop an application with 200 screens, you have to draw 200 screens by hand (with the mouse, but by hand). And if you want to do a change to 200 screen, you have to change the 200 one by one.
In OpenXava you don't define the user interface at all, it's generated automatically. So the step of drawing screens, just does not exist. That is more productive than any drag & drop environment, and allows you to have different UI with no extra cost, like a mobile UI, for example.
For me, Outsystem is just a very expensive Visual Basic. If you're looking for a cheap Outsystem, OpenXava is not for you. OpenXava has the same goal of Outsystem but uses a completely different approach.
I would say the OpenXava is a code oriented "Low Code" platform. It allows you to generate a full feature business application with little code, but you have to write some code.

Hi Pedro,
This issue shows the same trace:
https://stackoverflow.com/questions/32627671/eclipse-wont-run-on-fresh-windows-10
As the comment it seems that the uncompressor does not extract well all files.
What tool are you using to uncompress the zip?
Try to donwload the distribution and uncompress it again:
https://sourceforge.net/projects/openxava/files/openxava/6.6/
If still fails, tell me the amount of files inside your openxava-6.6 folder.
Help others in this forum as I help you.
Hi there,
I was able to uncompress the zip file with 7Zip and all when ok.
thank you for your help ;)
