Unable to validate minlength

In struts-validation, I am able to validate for "required" field on client side as well as server side. But if I want the field to be validated for a "minlength", I am unable to do it.

It is giving me an error, when validating for minlength:

Title Size can not be less than null characters.

Following is my .properties file:

Does anybody knows the answer for this. Thank you very much in advance.

I found the answer to this, the dtd to which the validation.xml and validation-rules.xml were pointing is a previous version. So just changed and it validates if the field is less than 3 characters.

But now I have got another error:
Now even if I enter 4 or more characters still I am getting the same error:
"Title Size can not be less than 3 characters."

Does anyone has any ideas abt this? Thanks for your time.

Are you sure you got the name of the variable right?
You define that a field needs to match 2 variables: required,minlength. Then you define a minlen?

Thanks for the reply. What you said was correct, the var:minlen is wrong, I defined it as var:minlength and its working.

But I have another problem now: I wanted to implement my own custom minlength validation as follows:

So I named it as "var:minfldlength", it is validating properly. But it was always gives the output as

"Title Size can not be less than null characters"

I do not know and I have tried all my best still the "null" is not taking the value "3" or whatever is used. But if I enter more than 3 chars, it validates properly and does not show any error.

See the code:

It is able to identify {0} from the properties file but not {1}. I do not know why.
I also tried using

still does not work.

This is the validation-rules.xml

The version of dtd I am using is validator_1_1_3.dtd

The custom Code for MinFldLength is as follows:

I do not know where the catch no matter how many ever times I try it gives my the same error:
TITLE SZE can not be less than null characters

Praise the Lord, finally just now as I was writing to this forum, I got this idea and that solved my puzzle:
In the validation-rules: I forgot to put this attribute in "validator" node:


Now I ran it and its working awesome.

Thanks for all the suggestions,
I agree. Here's the link:
