Jboss5.0.0下，項(xiàng)目使用Struts2.1.6+Spring2.5.5+Hibernate3（使用JPA的Hibernate實(shí)現(xiàn)）框架，但是在Jboss下啟動(dòng)時(shí)總是拋出“java.lang.RuntimeException: Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: esys”的錯(cuò)誤，錯(cuò)誤信息如下：

反編譯了jboss安裝目錄下common\lib中的“jboss-jpa-deployers.jar”文件，發(fā)現(xiàn)此文件中拋出異常的“PersistenceUnitInfoImpl”類，有這么幾句代碼：
if (metaData.getProvider() != null) { setPersistenceProviderClassName(metaData.getProvider());
    }

    if (metaData.getJtaDataSource() != null)
    {
      setJtaDataSource((DataSource)ctx.lookup(metaData.getJtaDataSource()));
    }
    else if (transactionType == PersistenceUnitTransactionType.JTA)
    {
      throw new RuntimeException("Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a jta-data-source for a JTA enabled persistence context named: " + metaData.getName());
    }

    if (metaData.getNonJtaDataSource() != null)
    {
      setNonJtaDataSource((DataSource)ctx.lookup(metaData.getNonJtaDataSource()));
    }
    else if (transactionType == PersistenceUnitTransactionType.RESOURCE_LOCAL)
    {
      throw new RuntimeException("Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: " + metaData.getName());
    }
按照這個(gè)意思就是persistence.xml中必須至少配置一個(gè)JNDI數(shù)據(jù)源，但是我使用的是spring管理的數(shù)據(jù)源，這個(gè)地方怎么會(huì)出現(xiàn)這種問(wèn)題呢？

問(wèn)題補(bǔ)充：
persistence.xml中“persistence-unit”是必須的，而且必須與applicationContext中指定的“persistenceUnitName”同名，再加上系統(tǒng)不使用JTA事物，transaction-type="RESOURCE_LOCAL"好像也是必須。其他的配置信息曾經(jīng)去掉過(guò)，可是不起作用。倒是在persistence.xml中加上一個(gè)空的

<non-jta-data-source></non-jta-data-source>

啟動(dòng)的時(shí)候不再拋異常了。
