  • 工作学习 / IT技术讨论 / A question about EJB, HELP ME!!! -linoopy(snoopy); 2001-1-18 {417} (#22317@0)
    Hi, jabber!

    It seems a long time I haven't ask you questions because I have been doing something about system analysis recently.

    Now there is a pure technical question about EJB confused me and my colleagues. That is how to realize the mutual utilization of different EJBs which in different EJB groups. I think it is a common question when a team use EJB to develop a project.

    Best wishes!

    • Sorry, can you speciify your question in more detail? -jabber(jabber); 2001-1-19 {98} (#22437@0)
      1) By "realize", did you mean "implement"?

      2) What did you mean by "mutual utilization"?
      • Thanks for your reply. The detail is ... -linoopy(snoopy); 2001-1-19 {443} (#22526@0)
        for example, in group A, there's EJB_1 and in group B, EJB_2. If the EJB_2 use some data created by the EJB_1, how to implement it? In our practice, when "RUN" the above method, there is no error but we couldn't get the returned data from EJB_1.

        BTW, this's the first time for me to realize that my specialized English in CS is very poor. I feel difficult to explain a little bit complex problem. So sorry for my ambiguity.

          Is your Bean 1 an entity bean? Is your Bean 2 a session bean?
          Waht do you mean by "some data created Bean 1"? I know that EntityBean represents persistence, but I could not understand "EJB
          creating data".

          By the way, we dont say EJB_1, _2, ... The natural expression is
          Bean 1, Bean A, or Account Bean, or Teller Bean, or Customer Bean.

          EJB means the whole artitecture, the whole Enterprise JavaBeans teachnology. The business component is EJB is simply called Beans.


          Pls feel discouraged about your English. Write more, you will be more and more proficientt. But I have one piece of advice: ENGLISH IS MORE IMPORTANT THAN EJB.
