Coarse-Grained EntityBeans


EJB programming & troubleshooting: Coarse-Grained EntityBeans

  1. Coarse-Grained EntityBeans (1 messages)

    Im reading some books about EJB and J2EE desing patterns. Each of this books told me that I should not use Fine-Grained EntityBeans.

    Ok, but what does Coarse-grained mean? Does it mean to use one EntityBean for two or more tables? Tabels which are related?

    In that case I think it is not possible to keep business logik out of EntityBeans, as often-mentioned.

    Yeah, basically you've got to write a sort of "universal" bean that knows which type of object it is dealing with.
    And can save dependency trees. Woohoo.

    Go with Hibernate instead if you can.
