If you're not otherwise using Hibernate just use a DocumentFilter.

If you want to force the user to enter exactly 5 digits then look at JFormattedTextField.
Alternatively you can set an input verifier to check what a user has entered and stop focus shifting to the next component if the input is invalid - see javax.swing.InputVerifier
