I explain my case to see if someone can help me. It turns out that I have some methods in Java (Eclipse) with which I call a REST service and I get certain data that I need to show on the screen. But my problem is that I do not know how to make the button I have on my screen call that method, that is, I can not integrate the code I have in Eclipse with a CUBA action.
Can anybody help me?
Thank you very much,
