Spring + Websphere 8.5：无法查找JNDI名称
有一个运行XA Datasource的Websphere AS 8.5。 还有一个Spring应用程序必须在此环境中工作并连接到数据源。 应用程序上下文由servlet加载，应用程序使用RmiExporters提供对某些服务的RMI访问（在单独的线程中共享），所有DAO的方法都用@Transactional标记。
如果我尝试从主线程向数据库写一些东西（例如在任何类的初始化期间），它可以正常工作。 但是如果我尝试通过RMI调用来编写（或使用HQL SELECT-query读取），我会看到一个exception：
org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [java:comp/websphere/ExtendedJTATransaction] at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:68) at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter$TransactionAdapter.(WebSphereExtendedJtaPlatform.java:156) at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter$TransactionAdapter.(WebSphereExtendedJtaPlatform.java:152) at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter.getTransaction(WebSphereExtendedJtaPlatform.java:124) at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter.getStatus(WebSphereExtendedJtaPlatform.java:119) at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.getStatus(JtaStatusHelper.java:73) at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.isActive(JtaStatusHelper.java:115) at org.hibernate.service.jta.platform.internal.TransactionManagerBasedSynchronizationStrategy.canRegisterSynchronization(TransactionManagerBasedSynchronizationStrategy.java:56) at org.hibernate.service.jta.platform.internal.AbstractJtaPlatform.canRegisterSynchronization(AbstractJtaPlatform.java:148) at org.hibernate.engine.transaction.internal.TransactionCoordinatorImpl.attemptToRegisterJtaSync(TransactionCoordinatorImpl.java:240) at org.hibernate.engine.transaction.internal.TransactionCoordinatorImpl.pulse(TransactionCoordinatorImpl.java:268) at org.hibernate.ejb.AbstractEntityManagerImpl.joinTransaction(AbstractEntityManagerImpl.java:1202) at org.hibernate.ejb.AbstractEntityManagerImpl.postInit(AbstractEntityManagerImpl.java:178) at org.hibernate.ejb.EntityManagerImpl.(EntityManagerImpl.java:89) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:179) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:174) at com.ibm.ws.jpa.management.JPAEMFactory.createEntityManager(JPAEMFactory.java:297) at org.springframework.orm.jpa.EntityManagerFactoryUtils.doGetTransactionalEntityManager(EntityManagerFactoryUtils.java:202) at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:211) at com.sun.proxy.$Proxy414.persist(Unknown Source)
实际配置如下：
persistence.xml中的持久性单元：
org.hibernate.ejb.HibernatePersistence jdbc/oracledatasource
Spring配置如下所示：
我可以尝试解决这个问题吗？
实际的解决方案是使用Spring的LOCAL_RESOURCE和LOCAL_RESOURCE持久性单元。
