validator in struts

[raghavendra vema]

Hi

I am using Validator in struts for field level Validation, The validation criterion is length should be exactly 9 characters and can take either of the patterns described below

pattern 1: all 9 characters are Numbers

pattern 2: 1st character is an Alphabet and rest 8 characters are Numbers

What is the shortest way of achieving this validation?

Thanks
ragha

As far as the validation for length goes, you can do it with validator-rules.xml by specifying the rule for length. But if you also want to validate for the 2 character sequences along with the length, then i would suggest you to combine the auto and manual validation. The validation for length can be done by the validator-rules.xml and put the logic for character validation in your form bean. You could also put this logic in the validator-rules.xml using the javascript tag. Or you could have javascript validation for character and auto validation for length. The choice is yours.
