在GlassFish v2中同时使用两个EntityManager时出现java错误
我有一个无状态会话bean（slsb），它依赖于另外两个充当DAO的bean。它们都使用JPA，因此每个bean都有一个EntityManager。它们指向不同的持久性单元（它们又是同一数据库的不同连接池——我不想牺牲这种灵活性）
在简单的代码中，它看起来是这样的（我的应用程序中的名字当然是真名）：
@Stateless
public class MyBean {
@EJB
private Dao1 dao1;
@EJB
private Dao2 dao2;
}
@Stateless
public class Dao1 {
@PersistenceContext(unitName = "unit1")
private EntityManager em1;
}
@Stateless
public class Dao2 {
@PersistenceContext(unitName = "unit2")
private EntityManager em2;
}
当我访问Dao1和Dao2中的MyBean方法时，我总是会得到以下错误：
SEVERE: Unable to complete container-managed transaction.; nested exception is: javax.transaction.SystemException: org.omg.CORBA.INTERNAL: JTS5031: Exception [org.omg.CORBA.INTERNAL: vmcid: 0x0 minor code: 0 completed: Maybe] on Resource [rollback] operation. vmcid: 0x0 minor code: 0 completed: No

FINE: An XAException occurred in prepare
没有别的（除了成千上万的FINE: TM: enlistComponentResources和FINE: TM: delistResource但它们看起来很正常）
两个连接池都配置为XADataSource。我目前的解决方法是，两个DAO中的一个使用此注释：
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
我不认为这是一个好的解决方案，但我不知道如何解决它，否则。我能以更好的方式消除这个错误吗
