In a EJB solution, one business logic EJB(SessionBean) want to get a data-processing work done, there are two options:
1) Create another session bean to perform this task, the main logic EJB will locate, create local interface then invoke a method.
2) Create a Plain Java Class with a logic method, the lord EJB then directly create the object of the class then invoke the method.
I am confusing this concern, I don't know which one can give us a achievement in performance.
Thanks for your reploy,
I suggest you ask this in the EJB/JBoss forum.
