以下是我的环境规范：
服务器：JBOSS6.1 最终版
持久层：以 Hibernate 作为持久提供者的 JPA（Hibernate 版本 3.6.6.Final）
应用架构类似于：Controller -> Session Beans -> Businell Logic Layer -> Builder (Hibernate layer) - DB (MYSQL)
我们正在使用在 persistence.xml 中配置的“RESOURCE_LOCAL”事务，如下所示：
<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<non-jta-data-source>java:/TestDS</non-jta-data-source>
我们使用如下所示的交易：
try {
txUtil.beginTransaction();
<-- some entity update etc here -->
if(some validation fail here){
txUtil.rollbackTransaction();
} else {
txUtil.commitTransaction();
} catch (Exception e) {
txUtil.rollbackTransaction();
} finally {
try {
txUtil.closeEntityManager();
} catch (BAException e) {
log.warn("Problem occurred while closing the EntityManager: " + e.getLocalizedMessage(), e);
}
}
上面使用的各种方法的代码类似于（下面不是精确的 impl，而是我们所拥有的粗略表示）：
beginTransaction(){
EntityManagerFactory emf = Persistence.createEntityManagerFactory("test");
EntityManager em = emf.createEntityManager();
if(em.isOpen())
{
transaction = em.getTransaction();
if(!transaction.isActive())
{
transaction.begin();
}
}
}
commitTransaction(){
if(em.isOpen())
{
EntityTransaction transaction = em.getTransaction();
if(transaction.isActive())
{
transaction.commit();
}
}
}
rollbackTransaction(){
if(em.isOpen())
{
EntityTransaction transaction = em.getTransaction();
if(transaction.isActive())
{
log.debug("EntityManager for thread (" +
Thread.currentThread().hashCode() +
") has active transaction (" +
transaction.hashCode() + "): rollback");
transaction.rollback();
}
}
}
closeEntityManager() {
if(em.isOpen()) {
EntityTransaction tx=em.getTransaction();
if(tx==null) {
log.debug("No transaction associated with EntityManager");
} else {
if(tx.isActive()) {
log.debug("EntityManager has active transaction, rolling out");
tx.rollback();
} else {
log.debug("EntityManager transaction was not active");
}
}
} try {
em.close();
}
}
问题是，每当我们进行回滚，然后如果我们尝试关闭实体管理器，它就会引发回滚异常。相同的堆栈跟踪如下：

以下是persistence.xml中与事务相关的属性

我在任何地方都看到并阅读了关于在回滚事务后关闭实体管理器的信息。但为什么我会得到上述异常？是预期的还是我在这里遗漏了什么？
提前非常感谢，如果您需要任何有关相同的进一步信息，请告诉我。
