Email Activation through Spring Security?

[deathfrag]

Is there any way to send an activation email on user registration through Spring Security?

Any other suggestions?

I can send mail using Spring's MailSender and SimpleMailMessage.

Do i have to implement the creating of activation url,saving the token, matching the token on click etc. ?

Is there any better way?

Spring Security does not provide a means for registering users other than an API (UserDetailsManager) and a few implementations (InMemoryUserDetailsManager, JdbcUserDetailsManager, LdapUserDetailsManager) for adding basic users. Most of the time I find that this functionality needs to be extended since there are usually special needs.
