How to interrupt focus events

I'm writing a field-level validation function for JTextField components.

The JTextField components are placed inside a JPanel container.
When the JTextField is created, the programmer specifies the initial
integer value, upper bound, and lower bound on this component.
At runtime, the user can change the initial value.
When focus is lost on this component, I validate whether or not the
value in the component is within range.
If not within range, I display a JOptionPane saying, "hey, your value is
out of range".

---> What I want to do is return focus back to the component whose value
is out of range.
However, in my travels I am finding that I can neither
1) Interrupt the "focus_gained" event on the next component in the
JPanel, nor
2) Return focus back to the component whose value was out of range.

Any ideas?
