Excepción en el modo de desarrollo GWT + Spring 3.1 + Hibernate 4.0.1

Question

Tengo un archivo de configuración GWT+Hibernate+JPA+Spring que está bien con Spring 3.0.x + Hibernate 3.6.x.Cuando actualicé a Spring 3.1 e Hibernate 4.0, se produce la siguiente excepción:

¿Existe alguna incompatibilidad conocida con Hibernate 4 y Spring 3.1?

Answer 1

Este problema está solucionado en hibernación 4.1.4.

---

Tuve el mismo problema y parece estar relacionado con el cargador de clases Jetty (el complemento GWT usa Jetty para el modo alojado), el complemento GWT e Hibernate (aunque aparentemente también aparece con otras bibliotecas).

Es similar al error mencionado aquí. Informe de error de hibernación pero en nuestros casos lo ejecutamos a través del complemento GWT y provoca una excepción ClassCastException para ConnectionProvider.

La solución mencionada en el informe de error debería solucionar ese problema en particular.

Para org.hibernate.service.classloading.internalClassLoaderServiceImpl, establezca el padre en nulo a través del constructor:

this.classClassLoader = new ClassLoader(null) {
        @Override
        protected Class<?> findClass(String name) throws ClassNotFoundException {
            for ( ClassLoader loader : classLoadingClassLoaders ) {
                try {
                    return loader.loadClass( name );
                }
                catch (Exception ignore) {
                }
            }
            throw new ClassNotFoundException( "Could not load requested class : " + name );
        }
};

Answer 2

Eliminar eJB3-Persistence.jar en el directorio /lib si ya está allí; Entra en conflicto con Hibernate-JPA-2.0-API-1.0.1.Final.Jar en Hibernate 4. Eso funcionó para mí después de tener este problema, logré alojar un GWT, Hibernate 4, primavera 3.1.1 Aplicación en OpenShift Environmenthift https://openshift.redhat.com/app/

Answer 3

Creo que no necesitas establecer <provider>org.hibernate.ejb.HibernatePersistence</provider> en persistence.xml. Controlar los documentos.
