How to make a crud jsf with ebj without id filed?

[Jamil Shreet]

Hi guys:
I use the option Jsf Pages From Entity class in Netbeans IDE, it works good but I do not want to generate code for id field(primary key) for each table, cause it is AutoIncrement.
but the Netbeans generates input text for all databease's field in the tables.......! even for Id.......!!
I changed the @Id @GeneratedValue(strategy) to be (GenerationType.AUTO) and delete the input text for id field from the page and tried to save a new data but it didn't work.....!!
I got error message in the page(may be not null).....!!
I tried to trace where he use the quiery to save data but I could not find anything....!!
please help me.
this is the code for session bean, entity class and jsf page

@Entity
@Table(name = "teachers_info", catalog = "online_exam", schema = "")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "TeachersInfo.findAll", query = "SELECT t FROM TeachersInfo t"),
    @NamedQuery(name = "TeachersInfo.findByTeacherId", query = "SELECT t FROM TeachersInfo t WHERE t.teacherId = :teacherId"),
    @NamedQuery(name = "TeachersInfo.findByTeacherFullName", query = "SELECT t FROM TeachersInfo t WHERE t.teacherFullName = :teacherFullName")})
public class TeachersInfo implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    [b]@GeneratedValue(strategy = GenerationType.AUTO)[/b][color=blue] [/color]
    @Basic(optional = false)
    @NotNull
    @Column(name = "teacher_id")
    private Integer teacherId;
    @Basic(optional = false)
    @NotNull
    @Size(min = 1, max = 255)
    @Column(name = "teacher_full_name")
    private String teacherFullName;

    public TeachersInfo() {
    }

    public TeachersInfo(Integer teacherId) {
        this.teacherId = teacherId;
    }

    public TeachersInfo(Integer teacherId, String teacherFullName) {
        this.teacherId = teacherId;
        this.teacherFullName = teacherFullName;
    }

    public Integer getTeacherId() {
        //teacherId = 0;
        return teacherId;
    }

    public void setTeacherId(Integer teacherId) {
        this.teacherId = teacherId;
    }

    public String getTeacherFullName() {
        return teacherFullName;
    }

    public void setTeacherFullName(String teacherFullName) {
        this.teacherFullName = teacherFullName;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (teacherId != null ? teacherId.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof TeachersInfo)) {
            return false;
        }
        TeachersInfo other = (TeachersInfo) object;
        if ((this.teacherId == null && other.teacherId != null) || (this.teacherId != null && !this.teacherId.equals(other.teacherId))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "kw.entitiesData.TeachersInfo[ teacherId=" + teacherId + " ]";
    }
}

session bean

@Stateless
public class TeachersInfoFacade extends AbstractFacade<TeachersInfo> {

    @PersistenceContext(unitName = "OnlineExamBetaPU")
    private EntityManager em;

    protected EntityManager getEntityManager() {
        return em;
    }

    public TeachersInfoFacade() {
        super(TeachersInfo.class);
    }
}

The Jsf page

 <h:form dir="rtl" id="myForm">
                    <h:panelGrid columns="2" dir="rtl">
                        #{msgs.course_name}
                        <h:inputText></h:inputText>
                        #{msgs.course_type}
                        <h:selectOneRadio id="test" onclick="hideShow(this.form,'test')">
                            <f:selectItem  itemLabel="#{msgs.mark}"></f:selectItem>
                            <f:selectItem  itemLabel="#{msgs.pass_failed}"></f:selectItem>
                        </h:selectOneRadio>
                        #{msgs.course_success_mark}
                        <h:inputText id="successMark"></h:inputText>
                        #{msgs.course_failed_mark}
                        <h:inputText id="failedMark"></h:inputText>
                        #{msgs.course_full_mark}
                        <h:inputText id="fullMark"></h:inputText>
                        #{msgs.faculty_name}
                        <h:inputText></h:inputText>
                        <h:outputLabel value="#{bundle.CreateTeachersInfoLabel_teacherId}" for="teacherId" />
                        <h:inputText id="teacherId" title="#{bundle.CreateTeachersInfoTitle_teacherId}"/>
                        #{msgs.teacher_name}
                        <h:inputText id="teacherFullName" value="#{teachersInfoController.selected.teacherFullName}"></h:inputText>
                        <h:commandButton value="#{msgs.save_data}" onclick="HideShow(this.form)" action="#{teachersInfoController.create}"></h:commandButton>
                    </h:panelGrid>
</h:form>

I delete the value attribute form input text for id field cause I supposed that it should be insert automaticlly inside database not by user.

sorry guys I forget the controller class

Your Managed bean code, line 65
getFacade().create(current);
If you CTRL+click "create" Netbeans should show you this method code. This will be where your object is saved to database.

But I don't think your data goes there.
Take a look at your JSF code.
<h:inputText></h:inputText>
Your input box is not connected with your managed bean. Managed bean should contain private String teacherFullName; and getName() and setName methods so you can use jsf code:
<h:inputText value="#{teachersInfoController.teacherFullName}"></h:inputText>
Then if you submit form it will be passed to managed bean so you can use it to create new teacher. Think about it.
