Welcome to the Ranch, Mohamed!
Those are messages from NetBeans and from the application builder that NetBeans used to create the application to
test.
They will NOT appear when you run the application stand-alone (without NetBeans) as you would in a production environment.
As a rule, you DO want to see those messages, since if you have problems getting the app to run, they'll tell you why.
