I'm trying to use Struts Validator to validate a 4 digit numeric using a mask:
<field property="ssn" depends="mask"> <arg0 key="register.form.ssn.displayname"/> <var> <var-name>mask</var-name> <var-value>^[0-9]{4}*$</var-value> </var> </field> Which causes: "Invalid expression: ^[0-9]{4}*$ Nested repetitions *?+ in expression" The expression '[0-9]^4' causes no exception but it throws out '0000' as not valid. Any assistance is appreciated. Greg =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
