La stratégie de transaction choisie nécessite l'accès au JTA TransactionManager ou Impossible de construire EntityManagerFactory

Question

J'utilise Spring 2.0.6 et Hibernate 3.2.x sur apache tomcat5.5, maintenant nous avions l'intention de changer nos fichiers de mapping hybernate en hybernate + support jpa fichiers de mapping. pour que nous avons créé des fichiers comme celui-ci

daoConfig.xml

</beans:bean> 

</beans: beans> 

dans mon daoconfig.xml i chemin donné pour persistence.xml et ceci est mon fichier persistence.xml

quand je suis en train d'exécuter mon serveur .i reçois l'erreur

me donner des suggestions

Answer 1

Tout d'abord, vous créez à la fois une SessionFactory Hibernate et JPA EntityManagerFactory. Cela n'a pas beaucoup de sens, sauf si vous avez une configuration très étrange, et vous devriez très probablement jeter la configuration de SessionFactory. Vous pouvez configurer Hibernate plain vanilla, ou vous pouvez configurer JPA, vous n'avez pas besoin des deux.

La création de la fabrique du gestionnaire d'entités échoue car vous avez spécifié JTA comme type de transaction, mais la classe de recherche du gestionnaire de transactions JTA n'est pas définie. (Vous l'avez défini dans la configuration Hibernate SessionFactory, mais pas dans votre config JPA.)

Ajouter à votre persistence.xml:

<persistence-unit name="payhub" transaction-type="JTA"> 

    ... 

    <properties> 
     <property name="hibernate.transaction.manager_lookup_class" 
      value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/> 
    </properties>    
</persistence-unit> 

Answer 2

Pour ceux qui utilisent Jboss AS, cette configuration pourrait être utilisée:

<property name="hibernate.transaction.manager_lookup_class" 
value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
