Hibernate NoSuchFieldError INSTANCE pero solo con Struts 1?

Question

Soy nuevo en Java e Hibernate (desarrollador de Rails and C#). De todos modos, tengo un programa de prueba que funciona bien con Hibernate, pero mi aplicación web real (Struts 1) se bloquea con:

SEVERE: Servlet.service() for servlet default threw exception java.lang.NoSuchFieldError: INSTANCE

estoy usando:

Hibernate 3.6.1 with Annotations

Struts 1 with Apache Tiles

C3P0 connection pool

Aquí está el programa que ctually OBRAS. Es parte del proyecto principal. Solo una prueba JAVA simple.

public class TestUser { 

    public static void main(String[] args) { 

    SessionFactory factory = HibernateUtil.getSessionFactory(); 
    Session session = factory.getCurrentSession(); 
    session.beginTransaction(); 

    String queryString = "from User where UserName = 'Quake'"; 
    Query query = session.createQuery(queryString); 

    User quake = (User)query.uniqueResult(); 
    session.getTransaction().commit(); 

    System.out.println(quake.getEmail()); 
    System.out.println("Active? " + quake.isActive()); 


    UserRepository userRepo = new UserRepository(); 

    System.out.println("User Quake: " + userRepo.findAll().get(0).getEmail()); 

    } 
} 

Funciona bien. Muestra un poco de datos de muestra.

Ahora, cuando intento hacer lo mismo en Struts, obtengo la excepción. Esto es lo que hace NO FUNCIONA:

public class ListUsers extends org.apache.struts.action.Action { 

    /* forward name="success" path="" */ 
    private static final String SUCCESS = "success"; 

/** 
* This is the action called from the Struts framework. 
* @param mapping The ActionMapping used to select this instance. 
* @param form The optional ActionForm bean for this request. 
* @param request The HTTP Request we are processing. 
* @param response The HTTP Response we are processing. 
* @throws java.lang.Exception 
* @return 
*/ 
@Override 
public ActionForward execute(ActionMapping mapping, ActionForm form, 
     HttpServletRequest request, HttpServletResponse response) 
     throws Exception { 


    List<String> listMsg = new ArrayList<String>(); 

    listMsg.add("Message A"); 
    listMsg.add("Message B"); 
    listMsg.add("Message C"); 
    listMsg.add("Message D"); 

    request.setAttribute("listMsg", listMsg); 



    UserRepository userRepo = new UserRepository(); // CRASHES HERE (see HibernateUtil) 
    String email = userRepo.first().getEmail(); 


    return mapping.findForward(SUCCESS); 
    } 
} 

Ésta es mi clase HibernateUtil:

public class HibernateUtil { 

    private static final SessionFactory sessionFactory = buildSessionFactory(); 

    private static SessionFactory buildSessionFactory() { 
    try { 
     // Create the SessionFactory from hibernate.cfg.xml 
     Configuration config = new Configuration(); // THIS LINE CRASHES IN STRUTS 

     // Add annotated classes 
     config.addAnnotatedClass(User.class); 

     config.configure(); 
     return config.buildSessionFactory(); 

    } catch (Throwable ex) { 
     // Make sure you log the exception, as it might be swallowed 
     System.err.println("Initial SessionFactory creation failed. WTFQNIL: " + ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
    } 

    public static SessionFactory getSessionFactory() { 
    return sessionFactory; 
    } 
} 

La línea de Configuration config = new Configuration() en el HibernateUtil es la línea que se estrella en Struts, pero no la aplicación de prueba.

Aquí está el volcado completo excepción:

¿Qué estoy haciendo mal?

Gracias!

Answer 1

Parece que tiene varias versiones de jar de Hibernate en el classpath.

Answer 2

@axtavt says right. Sé que ya resolvió el problema, publico mis comentarios, ya que podría ser útil para otras personas.

Si está utilizando dependencias de maven, supongamos que ya tiene su propia dependencia de hibernación. Y más tarde, otra dependencia (como org.codehaus.jackson o drools-spring) se agrega al pom. Puede causar este error porque org.codehaus.jackson y drools-spring tienen su propia dependencia en una versión diferente hibernate. excluir hibernación cuando agrega org.codehaus.jackson o drools-spring resolvería el problema.

Answer 3

Eliminar estas dos dependencias funcionó para mí.

<dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-commons-annotations</artifactId> 
     <version>3.0.0.ga</version> 
     <scope>runtime</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-annotations</artifactId> 
     <version>3.3.0.ga</version> 
    </dependency> 

Estos son mis dependencias de hibernación.

    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>3.6.3.Final</version>
