RE: Struts Validator 4 digit numeric
The * is a repetition operator, as the error said. You basically asked for
'exactly four' and 'zero or more' digits with the {4}* ... obviously that
doesn't make sense.

Yes, I did try that, it causes the same "Nested repetitions *?+ in
expression" error. However removing the * seems to have fixed things. I
thought the * had to be in the mask expression in validation.xml because it
was in all the examples I read in the docs. Where can I find a good Reg.
Expression tutorial? Thanks.

Did you try ^\d{4}$
Why do you include the * in your regexp - I think that's what's breaking it.

Subject: Struts Validator 4 digit numeric
I'm trying to use Struts Validator to validate a 4 digit numeric using a
mask:
mask
^[0-9]{4}*$
Which causes:
"Invalid expression: ^[0-9]{4}*$ Nested repetitions *?+ in expression"
The expression ^[0-9]^4*$ causes no exception but it throws out '' as
not
valid. (Obviously I have work to do on regular expressions.) Any
assistance is appreciated.

One of the best regex resources are the PERL man-pages:
