Error Creating SessionFactory Hibernate in myeclipse reverse engineered database

Question

I'm learning hibernate in myeclipse. I tried to reverse engineer a mysql table and follow the official myeclipse tutorial. All the xml files are generated but writing a simple test programme it gives me the following error:

Exception in thread "main" java.lang.NullPointerException
    at sor.hibernate.HitestTest.main(HitestTest.java:15)

The test programme is

package sor.hibernate;


import java.util.Date;

import org.hibernate.Session;
import org.hibernate.Transaction;


public class HitestTest {

    public static void main(String[] args) {

        HitestDAO dao = new HitestDAO();
        Transaction tx = dao.getSession().beginTransaction();

        Hitest hitest[] = new Hitest[10];
        for (int i = 0; i < hitest.length; i++) {
            hitest[i]  = new Hitest();
            hitest[i].setGreeting("saluto numero " + i*23);
            hitest[i].setRef(i+10);
            hitest[i].setDate(new Date(System.currentTimeMillis()));
            dao.save(hitest[i]);
        }
        tx.commit();
        dao.getSession().close();
    }
}

and the hibernate.cfg.xml is

<?xml version='1.0' encoding='UTF-8'?>

I have read the relevant questions and I have deleted the all trailing lines and spaces. But none of them has worked. The only thing I've add to these files reading the questions is package="sor.hibernate" attribute in the Hitest.hbm.xml The paths and... are all correct and they are all autogenerated.

More information. When I type from hitest in the HQL, it tells me org.hibernate.hql.ast.QuerySyntaxException: hitest is not mapped [from hitest] while from sor.hibernate.Hitest works well

Answer 1

Try removing the white space in

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd "
                                                       ^-- here

And in every other place where you might have done the same mistake.

Answer 2

Solving the problem indicated by @JB_Nizet I faced a new error about the validation. (Note: The problem of the space was a myeclipse bug. I tried with a project and it was myeclipse which added that evil space.) I added the following line to hibernate.cfg.xml and the problem was partly solved. The new error was (%%%% Error Creating SessionFactory %%%% org.hibernate.HibernateException: Error applying BeanValidation relational constraints)

<property name="javax.persistence.validation.mode">none</property>

The new error was hibernate sql query error. The id should have been assigned so I changed Hitest.hbm.xml to

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
