In your session bean, you can do the lookup of entity bean through the session
context. After that, you can use this reference to call any methods in the entity
bean.
Also,you can have a serialized object. In this object, you try to set all the return
fields you want them returned from the entity bean. What i mean here is that instead
of having so many getter methods you can use one "super" get and return a serialized
object containing all the stuffs you want.
By doing this way, you can prevent the number of calling from session bean to entity
bean.
