    Persist data in associated tables from single screen

    Vikram Chhetry Newbie

      Hi All,
      I am asking this question second time as I am still not able to fix this problem. I searched for it but could not get the solution.


      I have two tables(This is just a test scenario):-

      1.) user (user_id,name)

      2.) user_phone(user_phone_id,number,user_id)


      I want to insert user details and 2 different phone numbers for a user from a single screen.


      My screen should look like this:-




      Name----------TextBox

      Phone 1-------TextBox

      Phone 2-------TextBox

      Save Button



      Entity beans:-
      User.java


      @Entity
      @Table(name = "user")
      @Name("user")
      public class User implements java.io.Serializable {
      
           private Integer userId;
           private String name;
           private List<UserPhone> userPhones = new ArrayList<UserPhone>();
      
           public User() {
           }
      
           public User(String name, List<UserPhone> userPhones) {
                this.name = name;
                this.userPhones = userPhones;
           }
      
           @Id
           @GeneratedValue(strategy = IDENTITY)
           @Column(name = "user_id", unique = true, nullable = false)
           public Integer getUserId() {
                return this.userId;
           }
      
           public void setUserId(Integer userId) {
                this.userId = userId;
           }
      
           @Column(name = "name", length = 20)
           @Length(max = 20)
           public String getName() {
                return this.name;
           }
      
           public void setName(String name) {
                this.name = name;
           }
           @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "user")
           public List<UserPhone> getUserPhones() {
                return this.userPhones;
           }
      
           public void setUserPhones(List<UserPhone> userPhones) {
                this.userPhones = userPhones;
           }
      
      }
      



      UserPhone.java



      @Entity
      @Table(name = "user_phone")
      @Name("userPhone")
      public class UserPhone implements java.io.Serializable {
      
           private Integer userPhoneId;
           private User user;
           private String number;
      
           public UserPhone() {
           }
      
           public UserPhone(User user, String number) {
                this.user = user;
                this.number = number;
           }
      
           @Id
           @GeneratedValue(strategy = IDENTITY)
           @Column(name = "user_phone_id", unique = true, nullable = false)
           public Integer getUserPhoneId() {
                return this.userPhoneId;
           }
      
           public void setUserPhoneId(Integer userPhoneId) {
                this.userPhoneId = userPhoneId;
           }
           @ManyToOne(fetch = FetchType.LAZY)
           @JoinColumn(name = "user_id")
           public User getUser() {
                return this.user;
           }
      
           public void setUser(User user) {
                this.user = user;
           }
      
           @Column(name = "number", length = 20)
           @Length(max = 20)
           public String getNumber() {
                return this.number;
           }
      
           public void setNumber(String number) {
                this.number = number;
           }
      
      }
      



      AddUserAction.java



           @In
           User user;
      
           public void addUser() {
                // implement your business logic here
                log.info("addUser.addUser() action called with: #{user.name}");
                entityManager.persist(user);
                facesMessages.add("addUser #{user.name}");
           }
      



      xhtml



          <h:form id="addUserForm">
      
              <rich:panel>
                  <f:facet name="header">addUser</f:facet>
          
                  <s:decorate id="nameDecoration" template="layout/edit.xhtml">

                      <h:inputText id="name" required="true"
                                   value="#{user.name}"/>
                  </s:decorate>

              <div class="actionButtons">
                  <h:commandButton id="addUser" value="addUser" 
                          action="#{addUser.addUser}"/>                      
              </div>
      
          </h:form>
      



      I still do not know if seam supports this type of scenario. If it does then what is the right way of doing it and if it doesn't then how do I do it using hibernate.


      Can anyone please help me on this with some links.


      Any Help would be appreciated.


      -Vikram
