Newbie - Associated tables - How to get value and persist it

[valsart]

Hello !

I stuck with this problem for couple days...

My entities are generated using seam-gen.

My Session bean..

package test.etest.*;

import java.io.Serializable;
import java.util.List;

import javax.ejb.Remove;
import javax.ejb.Stateful;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.jboss.seam.annotations.Factory;

import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.datamodel.DataModel;
import org.jboss.seam.annotations.datamodel.DataModelSelection;

import test.etest.*;

@Name("userAction")
public @Stateful
class UserActionBean implements Serializable, UserAction {

 @DataModel
 private List<User> users;

 @DataModelSelection
 private User user;

 @PersistenceContext
 private EntityManager em;

 @Factory("users")
 public String find() {

 users = em.createQuery("select u from User u").getResultList();
 if (users.size() > 0) {
 return "/action.xhtml";
 }
 return null;

 }

 public void count() {
 // here i need to implement action that will take float value(address.num) from Address entity bean then divide it on value(user.payment) from User entity bean and then persist it to Results table.
 }

 public void update() {
 for (User user : users) {
 em.persist(user);
 }
 }

 @Remove
 public void terminate() {
 }

 public User getUser() {
 return user;
 }

 public void setUser(User user) {
 this.user = user;
 }

 public List<User> getUsers() {
 return users;
 }

 public void setUsers(List<User> users) {
 this.users = users;
 }

}

Can anyone help me ?

Regards,
Adam
