You cannot use Ext.form.VTypes on the server unless you use some sort of JavaScript server (node.js with an ExtJS adapter - if there is one). You didn't mention the programming language you use on the server, so the answer is quite generic. To return errors from form posts that will be displayed as form field errors, your response to the form submit must conform to the following format:

{
    success: false,
    errors: {
        oldpassword: "Your current password does not match"
    }
}

The important part is the errors-structure. It contains key-value-pairs with the key being the name of the form field you'd like to display the error on and the value being the error message that will be displayed.
