Is there someone that could answer questions concerning the HibernateTravelApp tutorial. I have written it a couple times per the tutorial and I am presently remodeling it to fit my own MySQL database. If there is a convenient way to transfer this data base along with the .zip of the netbeans project I would help me to be able to have someone look at it
I can .zip the project but it is possible to send the MySQL database?

If not I have the session bean for the HibernateTravelApp tutorialbelow and I am trying to understand how the drop down list is populated and how the query is configured to display the table data.

I see in the JSF it controls the table rows

maybe I should start by understanding elements in the xml Person.hbm

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
  <class dynamic-insert="false" dynamic-update="false"
      mutable="true" name="travel.Person" optimistic-lock="version"
      polymorphism="implicit" select-before-update="false" table="PERSON">
        <id column="PERSONID" name="personId">
            <generator class="increment"/>
        </id>
        <property column="NAME" name="name"/>
        <property column="JOBTITLE" name="jobTitle"/>
        <property column="FREQUENTFLYER" name="frequentFlyer"/>
        <set cascade="all-delete-orphan" inverse="true" lazy="true" name="trips" table="TRIP">
            <key column="PERSONID"/>
            <one-to-many class="travel.Trip"/>
        </set>
    </class>
</hibernate-mapping>

in my MySQL database I used the same structure as above.
I have this mapping structure for 3 classes and the HibernateUtil.class
for instance my database uses a Teacher.java

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package schedule;

/**
 *
 * @author depot
 */
public class Teacher {
    private int instrNum;
    private String instructor;
    private String state;

    public int getInstrNum() {
        return instrNum;
    }

    public void setInstrNum(int instrNum) {
        this.instrNum = instrNum;
    }

    public String getInstructor() {
        return instructor;

    }

    public void setInstructor(String instructor) {
        this.instructor = instructor;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }
    

}

this is the .hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
  <class dynamic-insert="false" dynamic-update="false" mutable="true" name="schedule.Teacher" optimistic-lock="version" polymorphism="implicit" select-before-update="false">
       <id column="instr_num" name="instructorId">
            <generator class="increment"/>
        </id>
     <!-- <property column="instr_num" name="instructorId">     -->
      <property column="instr_lname" name="instructor"/>
      <property column="instr_state" name="state"/>
      <set cascade="all-delete-orphan" inverse="true" lazy="true" name="instructorId" table="booking">
          <key column="instr_num"/>
          <one-to-many class="schedule.Booking"/>
      </set>
      
  </class>
</hibernate-mapping>

in my MySQL database I have a Instr_num field that relates to the Teacher.instrNum yet this field from the db Instr_num is not AUTO_INCREMENT so I was questioning the use of

<id column="instr_num" name="instructorId">
            <generator class="increment"/>
        </id>

I am not sure why this would be different from the other properties

and concerning the code

<set cascade="all-delete-orphan" inverse="true" lazy="true" name="instructorId" table="booking">
          <key column="instr_num"/>
          <one-to-many class="schedule.Booking"/>
      </set>

I believe this is a type of list that will only except Teacher.instructor with no duplication

ultimately I would like to have the drop down list select a Teacher and display info from the booking class concerning dates and times with students
Is this xml capable of this?

I know my line of questions are scattered so any input on any subject would be apreciated.

I think my first concern is to understand how the Option[] and the q.query and other areas are working. from the tutorial HibernateTravelApp

I introduced a lot of code that I will try to formulate more spicific questions to understand the tutorial if any one is able to help.
Thanks

Has any one worked with the HibernateTravelApp tutorial

Posting a thread on the same topic as a previous thread that you posted within 12 hours is wrong

i think this thread has something on it: LINK

come to think of it, you started it, 8 hours ago (7 from when you posted this). and if noone replied they either don't know, or haven't seen it yet. you should wait at least a day, and post exactly what problems your having, what exceptions are thrown, why you don't understand, at least in your last thread you did post what you knew, but this one is very vague. in the first thread you said you would formulate more specific questions, which if you did you should post in the same thread that you had started earlier.

my intent is not to be harsh, i just think that posting another thread, when you already have one on the topic is not very good. be a little more patient when posting a new thread about the same topic. wait a a day, i haven't had the problem that i needed answered quickly, but without urgency, i wait until the previous thread is off of the first page page of the board, or "bump" my old thread.

This article has been dead for over six months. Start a new discussion instead.
