SessionBean or Plain Java Class

[a13519]

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,

Probably neither is going to greatly effect your performance. I would expect the actual logic processing will hide any performance differences anyways.
You might want to try having a java class that handles all changes to your model state. It then can delegate calls to other logic classes, scripts, stored procedures etc either via an event model or reflection
