Re: How to validate multiple fields with the same name

[Pranava Swaroop]

Murali , Apologies its not exactly interceptors, Two ways we can validate
the input fields , one is using the configuration set for each of the
fields and the other is programatic way.

For example say we need to create a validation xml for user login, we
create User-validation.xml (Format is Action-validation.xml for different
classes). I just referred few inbuilt validators in the struts 2 site and
below are the ones


   -

     required validator.
    -

     requiredstring validator
    -

     int validator
    -

     date validator
    -

     expression validator
    -

     fieldexpression validator
    -

     email validator
    -

     url validator
    -

     visitor validator
    -

     conversion validator
    -

     stringlength validator
    -

     regex validator

   And these dont require registration when you are using them in your
   application. Just add the action validation xml to the classes directory.
   It works


<!DOCTYPE validators PUBLIC
        "-//OpenSymphony Group//XWork Validator 1.0.2//EN" "
http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd";>
<validators>
    <field name="userName">
        <field-validator type="requiredstring">
            <message>Username is required</message>
        </field-validator>
    </field>
    <field name="password">
        <field-validator type="requiredstring">
            <message>Password is required</message>
        </field-validator>
    </field>
</validators>

This is one of the easiest solutions to isolate the most commonly used
validations for the fields using configuration in struts2.

Hope this helps. Thanks
