Which of the following statements regarding the lifecycle of a session bean are correct?

1. java.lang.IllegalStateException is thrown if SessionContext.getEJBObject() is invoked when a stateful session bean instance is passivated.

2. SessionContext.getRollbackOnly() does not throw an exception when a session bean with bean-managed transaction demarcation is activated.

以下哪一个关于一个会话bean的生命周期是正确的吗？
1。java.lang.illegalstateexception如果将sessioncontext。getejbobject()时调用有状态会话bean实例的钝化。
2。sessioncontext getrollbackonly()。不抛出异常，当一个会话Bean管理的事务划分豆激活。
3。一个例外是不被当为sessioncontext getusertransaction()。容器豆afterBegin方法管理事务。
4。JNDI访问Java：压缩机/环境都是有状态会话bean的sessionsynchronization方法允许容器管理的事务划分。
5。资源管理器的访问有状态会话bean使用bean管理事务sessionsynchronization.afterbegin方法不会抛出异常。
