Session EJB and Entity

[warx_sg]

Hi all,

I have developed an application with some session EJB which call some entity EJB.
All entitie have a local interface wich is used by the session EJB to acces to the database.
When i deploy the application on a cluster i got some errors about session EJB can't get entity bean because these entities don't have a remote interface.
So, must all entities bean, in a cluster, have remote interface instead of local interface ?
If yes, just why ?
Cheers.

Hi,

I don't know how it exactly works but I made the experience with other J2EE Application servers that in order to do load balancing over all the ejb containers in the cluster, it is better to have a remote interface because then a new entity bean can be created in an other ejb container than the session bean which creates the entity bean.
But normally when ther is only a local interface for the entity bean, the entity bean must be created in the same ejb container where the session bean is executed.
So I don't know about the exception but this could be a reason, but I AM NOT SURE
