I wrote a DSL using Xtext specification for a school project, and i need to run a java file inside this environment using a button .

I managed to create the button but i still don't know how to access the file in the new environment, and then how to run it.

You can find an example for that in the blog of Christian: https://www.dietrich-it.de/xtext/2011/10/15/xtext-calling-the-generator-from-a-context-menu.html

I am new to this, but I will do my best to explain to you what I want to do.
I created a DSL(Global constraints written in a certain format), after that I want to use the file created based on these DSL rules, in the new eclipse application environment , as an input to my java application.
I managed to do so but I want to run the main class using a UI button, is that possible ? if so how can I configure it ?

Thank you, that helped a bit, but I still don't know where to put these configurations so that I can access them in the new eclipse application launched.
PS : as I mentioned before, I created a button and I linked it with a class that extends AbstractHandler and implements IHandler.
