Struts <field-validator> for email

Hello,

I have attached 2 validators to validate wether the user enters or leaves the email field blank and also a validator to see if is valid or not valid from the default.xml from opensymphony.

How do I add an other validator to tell me that the email already exists?  Note: im already making a DB call and already know that the email exists... Just need the actual 3rd validator.  

Please help!!!

<field name="newCompanyAdminEmail">
        <field-validator type="requiredstring">
            <message>Please enter the admin email.</message>
        </field-validator>
        <field-validator type="email">
            <message>The email address you entered is not valid.</message>
        </field-validator>
    </field>

but why would you want to do it, since first validator is doing exactly the same.

may be i didn't understood the requirement, can you help?

sure, the first validator checks to see if the field is blank or not, the second validator checks to see if it has a @ and a . , the third validator will check to see if the email entered by the user already exists in the database.  im making the java call and know if it exists or not, but i need to catch that action using a validator not a javascript popup.

for this, won't you need to make a server side request and then check for its existence? I dont think this is in the scope of struts validator.

i would suggest that you make an ajax request to check for its existence, so that user can continue to fill other fields

Depends what kind of 'validation' you want.

If you want to do client-side validation, you have no choice but Ajax.

If you want to do server-side validation, then the user will have to submit the form and consequently you can use code to validate it.

You cannot do client-side validation with simple javascript due to the fact that the userlist is lying in the DB (which the client, being a web browser on another computer, does not have access to).
