Answer 1

i got solution for captcha validation in grails. Any one needed can use this `def simpleCaptchaService

def save = { boolean captchaValid = simpleCaptchaService.validateCaptcha(params.captcha) }`

This should be kept in controller you get the result in boolean format ie true or false get this value and validate it.
