JFormattedText field

http://img381.imageshack.us/img381/1583/ftfbv0.jpg
Kako da podesim u NetBeansu da mi JFormattedTextField prima samo brojeve, i to maksimalno njih 5?
Odnosno koji patern da ukucam u polje Format na slici sa linka?

# Any valid number (Character.isDigit).
' (single quote) Escape character, used to escape any of the special formatting characters.
U Any character (Character.isLetter). All lowercase letters are mapped to uppercase.
L Any character (Character.isLetter). All uppercase letters are mapped to lowercase.
A Any character or number (Character.isLetter or Character.isDigit).
? Any character (Character.isLetter).
* Anything.
H Any hex character (0-9, a-f or A-F).

Znaci tebi treba #####

Tako sam i uradio, ali kada recimo ukucam 444, on mi validira to, i na polje setuje prazan string, odnosno to nije validno.
Kada stavim #####, onda je jedino validan petocifreni unos, a sve manje od toga je nevalidno.

Pa, zar bas niko ne zna da pomogne? Meni deluje kao problem koji ima resenje :)
