# User Registration Event Control

The User Registration Event control provides a convenient way to dispatch a UserRegistrationEvent event to the event service. Use this control in a Page Flow for one of two primary purposes:

- To trigger a campaign action when the event occurs.
- To persist information about the event for use in behavior tracking and analytics.

This control may not be used in a Java Web Service, because the request and session objects it requires are unavailable from a Java Web Service.

You can obtain the Session and Request objects from a Page Flow with the following code:

HttpServletRequest request = this.getRequest();
