jfinal事务问题!? 400 报错

@jfinal

@Before(Tx.class)
public void AController()Throws Exception{
    UserModel m = new UserModel()
    m.set(....);
    m.set(...);
    m.save();
    createCard(m);
}
private void createCard(UserModel m)throws Exception{
    CardModel cm = new CardModel();
    cm.set(....);
    cm.setUserId(m.get("id"));
    cm.save();
    othercode......
}

AController和createCard方法是在同一个事务内么?如果createCard方法在othercode处出错,那么userModel和cardModel是否都能回滚呢?
