EJB CMT TransactionAttributeType.REQUIRES\u NEW不起作用

    @Stateless    @LocalBean
    public class MySLSB {

            @Resource
            SessionContext ctx;
            @PersistenceContext(unitName = "myPU")
            EntityManager em;

            public void T1() {
                em.persist(new MyEntity(1L)); //T1 created!
/* wrong call to plain java object               
 T2();
 */     
//corrected by lookup its business object first 
ctx.getBusinessObject(MySLSB.class).T2();   
     ctx.setRollbackOnly();
            }

            @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
            public void T2() {
                em.persist(new MyEntity(2L)); //T2 created!
            }
        }

但T1将被回滚。

预期结果:

T2:插入myentity set id=2;

T1:回滚;

-&燃气轮机;id=2的行是在DB中创建的。

插入myentity set id=1;

回降;

有什么问题吗?谢谢!
