How to call a method in session bean from JSF (xhtml) page.

JSF

<h:commandButton type="submit" value="Register"
action="#{register12.register()}"/>

SESSION BEAN

package org.domain.FinalSeam.session;

import java.util.List;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.domain.FinalSeam.entity.User;
import org.hibernate.validator.Valid;
import org.jboss.seam.annotations.IfInvalid;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Outcome;
import org.jboss.seam.log.Log;
import org.jboss.seam.core.FacesMessages;
@Stateless
@Name("register12")
public class RegisterActionBean implements Register
{
@In
@Valid
private User user;

@PersistenceContext
private EntityManager em;

@IfInvalid(outcome=Outcome.REDISPLAY)
public String
register()
{
List existing = em.createQuery("select username from
User where
username=:username")
.setParameter("username", user.getUsername())
.getResultList();

if (existing.size()==0)
{
em.persist(user);
return
"success";
}
else
{
FacesMessages.instance().add("User #{user.username}
already
exists");
return null;
}
}

}

But it show some error "register12" is not bound"

Is it correct way or need to modify some xml/file

I expecting a big hand from all

Thanks in advance
