The problem is --->operacionesRHRemoto = (OperacionesRHRemoto) context.lookup("RHumanosEAR/"+OperacionesRH.RemoteJNDIName);
session.setAttribute("operacion", operacionesRHRemoto);
the problem is:
-when i use a stateful bean that call a class DispatchAction it doesnt work,
-when I use an ActionClass it doesnt work, it works fine,
-when I call the stateful using a simple class it works too,
Maybe I need to use a library, Idont know ... please help me.
