[JBoss-user] [EJB/JBoss] - Re: ClassCastException invoking LocalHome finder methods on

2005-04-19 Thread felandres 
Hi all,

  Since NOBODY reply my question, I'll answer it myself... the problem was 
caused by wrong use of (Home/Remote) interface pairs.
  If you're using LocalHome you MUST use the EJB's Local interface!

  I hope this could help somebody...

[JBoss-user] [EJB/JBoss] - ClassCastException invoking LocalHome finder methods on BMPs

2005-04-15 Thread felandres 
Hi all (again...), 

I'm having problems on invoking BMPs finder-methods (only those that returns 
various Value Objects within a Collection) through their local home interface. 
If I call them from the home interface it works pretty fine, but when I call 
from the local home I get a ClassCastException... 
I'm using a Stateless Session Bean to encapsulate the business logic, so 
they're in the same VM. 

PS: I also tried to call a testing method in the (Facade) Session Bean that 
referenciates the local home interface of the EJBs, but I got the same error. 

I didn't find any reason for this... 
Any help is very welcome!

Thankx.
