La strategia di transazione scelta richiede l'accesso a JTA TransactionManager o Impossibile costruire EntityManagerFactory

Question

Sto usando Spring 2.0.6 e Hibernate 3.2.x su apache tomcat5.5, ora abbiamo progettato di cambiare i nostri file di mappatura hybernate nel supporto hybernate + jpa mappatura dei file. per questo abbiamo creato i file come questo

daoConfig.xml

<beans:bean id="dataSource" 
    class="org.springframework.jndi.JndiObjectFactoryBean"> 
     <beans: property name="jndiName"> 
    <beans: value>java:/comp/jdbc/Paymentsdb</beans:value> 
    </beans: property> 
    </beans: bean> 
<beans: bean id="sessionFactory" 
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
    <beans: property name="useTransactionAwareDataSource" 
    value="true" /> 
    <beans: property name="dataSource"> 
    <beans:ref bean="dataSource"/> 
    </beans: property> 
    <beans: property name="hibernateProperties"> 
    <beans: props> 
    <beans:prop key="hibernate.dialect">${database.target}</beans:prop> 
    <beans:prop key="hibernate.connection.isolation">3</beans:prop> 
    <beans:prop key="hibernate.current_session_context_class">jta</beans:prop> 
    <beans:prop key="hibernate.transaction.factory_class">com.atomikos.icatch.jta.hibernate3.AtomikosJTATransactionFactory 
    </beans:prop> 
    <beans: prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup 
    </beans: prop> 
    <beans: prop key="hibernate.connection.release_mode">on_close</beans: prop> 
    <beans: prop key="hibernate.show_sql">false</beans: prop> 
    </beans: props> 
    </beans: property> 
</beans: bean> 

<beans: bean id="jpaTemplate" 
    class="org.springframework.orm.jpa.JpaTemplate"> 
    <beans: property name="entityManagerFactory"> 
    <beans:ref bean="entityManagerFactory" /> 
    </beans: property> 
</beans: bean> 

<beans: bean id="entityManagerFactory" 
     class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <beans: property name="dataSource"> 
    <beans:ref bean="dataSource" /> 
    </beans: property>  
     <beans: property name="jpaVendorAdapter"> 
     <beans:bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
         <beans: property name="generateDdl" value="false"/> 
         <beans: property name="showSql" value="true" /> 
         <beans: property name="databasePlatform" value="${database.target}" /> 
       </beans: bean> 
     </beans: property> 
     <beans: property name="persistenceXmlLocation"> 
    <beans:value>classpath:META-INF/persistence.xml</beans: value> 
    </beans: property>  
    </beans: bean> 

<beans:bean id="atomikosTransactionManager" 
    class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" 
    destroy-method="close"> 
    <beans:property name="forceShutdown" value="true" /> 
    <beans:property name="startupTransactionService" value="true" /> 
</beans:bean> 

<beans:bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp"> 
    <beans:property name="transactionTimeout"> 
     <beans:value>300</beans:value> 
    </beans:property> 
</beans:bean> 

<beans:bean id="transactionManager" 
    class="org.springframework.transaction.jta.JtaTransactionManager"> 
    <beans:property name="transactionManager"> 
     <beans:ref bean="atomikosTransactionManager" /> 
    </beans:property> 
    <beans:property name="userTransaction"> 
     <beans:ref bean="atomikosUserTransaction" /> 
    </beans:property> 
</beans:bean> 

</beans: beans> 

nel mio daoconfig.xml ho dato percorso per persistence.xml e questo è il mio file persistence.xml

<?xml version="1.0" encoding="UTF-8"?> 
<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="1.0"> 
<persistence-unit name="payhub" transaction-type="JTA">

      ---------- 
      ---------- 
    <class>com.evolvus.common.model.TaBooks</class> 
    </persistence-unit> 
</persistence> 

qui sto specificando il mio nome file mappatura orm
il file orm.xml è

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

</entity> 
    </entity-mappings> 

quando sto cercando di eseguire il mio server .i sto ottenendo l'errore

darmi qualche suggerimento

Answer 1

Prima di tutto, si sta creando sia un SessionFactory di Hibernate e JPA un EntityManagerFactory. Ciò non ha molto senso a meno che non si abbia una configurazione molto strana, e molto probabilmente dovresti eliminare la configurazione di SessionFactory. È possibile configurare Hibernate pianura semplice o configurare JPA, non è necessario entrambi.

La creazione della factory gestore entità non riesce perché è stato specificato JTA come tipo di transazione, ma la classe di ricerca gestore transazioni JTA non è definita. (Hai definito nella configurazione Hibernate SessionFactory, ma non nella configurazione JPA.)

Aggiungi questo al vostro 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

Per coloro che utilizzano JBoss AS, questa configurazione potrebbe essere utilizzato:

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