Integrate existing application

Integrate existing application

  
Hi,

I am a newbie to the outsystem platform. My question is if I have an existing application on J2EE platform which uses MySql DB on the backend, Can I import that whole application into the Outsystem platform to continue further development using OutSystems?
you can use mysql without a problem.

for the logic/pages I doubt it.
use iframes/canvas to show the pages, but for the rest, nope.
