Hibernate ClassNotFoundException for Configuration

Question

I have been trying to setup Wicket with Hibernate and MySQL for a good few hours at this point. I am using Maven as for dependency management. Admittedly I am a bit new to Jave 2EE and if there is anything else I can provide let me know and I will get it.

My HibernateUtil (this is one of many attempts but make the most sense to me)

public class HibernateUtil{
    private static SessionFactory sessionFactory = initSessionFactory();
    private static Properties getHibernateProperties(){
        return new Properties(){
        {
            setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
            setProperty("hibernate.connection.driver_class","com.mysql.jdbc.Driver");
            setProperty("hibernate.connection.url","jdbc:mysql://192.168.33.15/eventApp");
            setProperty("hibernate.connection.username","root");
            setProperty("hibernate.connection.password","test101");
        }
    };
}

private static SessionFactory initSessionFactory(){
    Configuration cfg = new Configuration();
    cfg.setProperties(getHibernateProperties());
    return cfg.buildSessionFactory();
}
public static SessionFactory getSessionFactory(){
    return sessionFactory;
}

}

I can look in the JARs and see the Configuration.java yet when I save a form that calls to HomePage.java

public class HomePage extends BaseTemplate {
    Event event= new Event();
    // TODO Add any page properties or variables here

/**
 * Constructor that is invoked when page is invoked without a session.
 * 
 * @param parameters
 *            Page parameters
 */
public HomePage(final PageParameters parameters) {

    Form createEventForm = new Form("createEventForm"){
        @Override
        protected void onSubmit() {
            super.onSubmit();
            System.out.println("### Event name: " + event.getEventName());

            SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
            Session session = sessionFactory.openSession();
            session.getTransaction().begin();
            session.persist( event ); // cascades the tool & skill relationships
            session.getTransaction().commit();
        }
    };

    TextField eventName = new TextField("eventName",new PropertyModel(event, "eventName"));

    createEventForm.add(eventName);
    add(createEventForm);

}

}

The call to HibernateUtil fails with the below

<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>jta</artifactId>
    <version>1.0.1B</version>
</dependency>

needs to be added, also make sure that jar is in your class path.

Is there a specific reason you chose 1.0.1B I was getting an error with that and looked into it. I found [link]stackoverflow.com/questions/19086523/… which suggested using 1.1. I did and all appears to be working

glad to hear that problem got resolved. specific version is not required. using the latest version is fine.
