Swing validation

I have a frame and an entity class.

Where do I put the validation of the input fields?

In the form inside the submit button listener?

Create another class to validate the fields and pass a bean as a parameter to be validated?

Add validation methods in my entity class?

what do you suggest?

Thanks

Marcos
