hi, I'm a newbie to seam 2. I'm attempting to do pretty simple thing with Seam. Created a web application and manually create an entity and persist.

I have used Seam Generate Entities to reverse engineer my sample table ( Users ). Here is what I've got..( Ive added ID generator stuff )

@Entity
@Table(name = "USERS", schema = "MYSCMA")
public class Users implements java.io.Serializable {
        private static final long serialVersionUID = -4129911784324770432L;
        private Long UId;
        private String userId;
        private String firstName;
        private String lastName;
        private String active;
        private int failedAttempts;
        private Date dateCreated;
        private Date dateModified;
        private String password;

        public Users() {
        }

        public Users(Long UId, String userId) {
                this.UId = UId;
                this.userId = userId;
        }

        public Users(Long UId, String userId, String firstName,
                        String lastName, String active, int failedAttempts,
                        Date dateCreated, Date dateModified, String password) {
                this.UId = UId;
                this.userId = userId;
                this.firstName = firstName;
                this.lastName = lastName;
                this.active = active;
                this.failedAttempts = failedAttempts;
                this.dateCreated = dateCreated;
                this.dateModified = dateModified;
                this.password = password;
        }

        @Id
        @Column(name = "U_ID", unique = true, nullable = false, precision = 22, scale = 0)
        @NotNull
        @SequenceGenerator(name="IDSequence", sequenceName="USR_SEQ")
        @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="IDSequence")
        public Long getUId() {
                return this.UId;
        }
...
...

It also generated UsersHome.java and UsersList.java

Haven't changed anything in UsersHome.java..here is the generated code..

@Name("usersHome")
public class UsersHome extends EntityHome<Users> {

        /**
         * 
         */
        private static final long serialVersionUID = -2888773603946593589L;

        public void setUsersUId(BigDecimal id) {
                setId(id);
        }

        public BigDecimal getUsersUId() {
                return (BigDecimal) getId();
        }

        @Override
        protected Users createInstance() {
                Users users = new Users();
                return users;
        }

        public void load() {
                if (isIdDefined()) {
                        wire();
                }
        }

        public void wire() {
                getInstance();
        }

        public boolean isWired() {
                return true;
        }

        public Users getDefinedInstance() {
                return isIdDefined() ? getInstance() : null;
        }

}

Now, I'v created an Seam Action and trying to create a new Users entity object and persist to the database.

Here is what I'm doing in Action method..

UsersHome usersHome = new UsersHome();
        Users newUser = usersHome.createInstance();
        newUser.setActive("Y");
        newUser.setUserId("manualUser");
        newUser.setPassword("password");
        Timestamp currentTimeStamp = new Timestamp(System.currentTimeMillis());
        newUser.setDateCreated(currentTimeStamp);
        newUser.setDateModified(currentTimeStamp);
        newUser.setFailedAttempts(0);
        newUser.setFirstName("firstName");
        newUser.setLastName("lastName");
        usersHome.setInstance(newUser);
        usersHome.persist();

Even newbie like me, feel that I'm missing something here..like either using a session or some a persistent manager of some sort..but I couldn't work out how or what to use it..so I just test it out..

I'm getting the following error..
java.lang.NullPointerException
        at org.jboss.seam.framework.Controller.debug(Controller.java:197)
        at org.jboss.seam.framework.Home.createdMessage(Home.java:90)
        at org.jboss.seam.framework.EntityHome.persist(EntityHome.java:87)
        at org.domain.usermanager.session.UserCreator.userCreator(UserCreator.java:38)

I suspect I'm not setting something..but, as I said, not sure what..

Could you please let me know how I can use session/persistent manager with seam/hibernate combination.

What does EntityHome object do..and what is the correct way of manually creating an entity object and persisting.

Any suggestions/pointers would be very helpful.

Cheers.
