abstractMethod error in hibernate 4.1

Question

I am trying with hibernate 4.1 . I configure settings by seeing this but still, I am getting session factory impl Abstract method error. Here is my code and I am using maven for downloading jars

hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.archive.autodetection">class,hbm</property>  
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>  
        <property name="hibernate.show_sql">true</property>    
        <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>    
        <property name="hibernate.connection.username">SA</property>    
        <property name="hibernate.connection.password"></property>    

        <property name="hibernate.hbm2ddl.auto">create</property>    
        <mapping class="main.java.entity.Advocate"></mapping>
            <mapping class="main.java.entity.Case"></mapping>
    </session-factory>
</hibernate-configuration>

This my config class:

package main.java.service;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

import main.java.businessTier.CaseTO;
import main.java.entity.Advocate;
import main.java.entity.Case;

public class LegalService {


 Configuration configuration = new Configuration().configure();

      ServiceRegistry  serviceRegistry = new ServiceRegistryBuilder().applySettings(
                configuration.getProperties()). buildServiceRegistry();
     SessionFactory   sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    Session session;

    public int registerCase(CaseTO caseTO) {
           session=sessionFactory.openSession();
           session.beginTransaction();

        Case c = new Case();
        Advocate a = new Advocate();
         a.setAdvocateId(caseTO.getAdvocateId());
        c.setAdvocate(a);
        c.setClientAge(caseTO.getClientAge());
        c.setClientName(caseTO.getClientName());
        c.setDate(caseTO.getDate());
        c.setDescription(caseTO.getDescription());
        session.persist(c);
        session.getTransaction().commit();
        return c.getCaseNo();



    }

}

Error:

Answer 1

hibernate-envers dependency in your pom.xml is creating issue. Please remove hibernate-envers dependency from you pom.xml

Use only hibernate-core and hsql dependency.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.1.4.Final</version>
</dependency>

<dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <version>2.3.3</version>
</dependency>

It will work then. Let me know, if it worked or not. At my end it worked.
