    作为轻量级的容器,Spring常常被认为是EJB的替代品。我们也相信,对于很多 (不一定是绝大多数)应用和用例,相对于通过EJB容器来实现相同的功能而言, Sping作为容器,加上它在事务,ORM和JDBC存取这些领域中丰富的功能支持, Spring的确是更好的选择。-As a lightweight container, Spring is often considered an alternative to EJB. We also believe that for many (not necessarily the overwhelming majority of) applications and use cases, as opposed to through the EJB container to achieve the same functionality in terms of, Sping as containers, together with its affairs, ORM and JDBC access to these areas of rich the function of support, Spring is indeed a better choice.

  • This paper addresses a stochastic
    This paper addresses a stochastic-#ow network in which each arc or node has several capacities and may fail. Given the demand d, we try to evaluate the system reliability that the maximum #ow of the network is not less than d. A simple algorithm is proposed "rstly to generate all lower boundary points for d, and then the system reliability can be calculated in terms of such points. One computer example is shown to illustrate the solution procedure.-This paper addresses a stochastic-#ow network in which each arc or node has several capacities and may fail.
