I'm using struts and hibernate as framework of my app.

I have a class Hibernation that crate the factory of hibernate, etc, etc.... and implements Filter , so, I have a method doFilter:




On the red line get the error, but I don't know so much.
I know that the doFilter is executed after and before pass for a jsp, but I don't know by what jsp, It sounds like random, i dont know.

Thanks Zenikko, but I know that. I'm looking for another option. My objetive is have "Services" distributites, like EJB for web application can consuming this ones. But If I have to set lazy=fase I'm losing.
I passed my first problema. Now have another. I'll try to explain with my pour English:

I have 3 proyects:

1-Java Library Proyects. It contain:
1.1 A busissnes class "Area" what implements Serializable with 3 attributes: id, description, areaFunction (type AreaFunction) and setters, getters and constructor.
1.2 A busissnes class "AreaFunction" what implements Serializable with 2 attributes: id and description and setters, getters and constructor.
1.3 An interface "ServiceArea" with a method "getAreaById(Long id)" that return an "Area". Thats all for this proyect.

2-EJB modules. It contains:
2.1 Include proyect 1.
2.2 An implementations of "ServiceArea" with @Remote and @Stateless ( mappedName="ServicieArea" ) annotation. This implementation get a method "getAreaById(Long id)" that return the "Area" Object
2.3 This proyect use Hibernate to get an area form database.

3- Web Application.
3.1 Include proyect 1.
3.2 It have an Action of Struts to do this:
InitialContext context = new InitialContext();
ServicieArea service = (ServicieArea) context.lookup("ServicieArea");
Area area = service.getAreaPorId(223L);


It didn't work because I did not include into web application JARs of hibernate, but now It works fine. My problema now is when I tried to get "areaFunction" attribute from "area".

My JSP recieve attribute "area" from action (thats ok). I tried to get from "area" the object "AreaFunction" and I get this error:

Hi, I have the same (or similar) problem. I have a web application client that does a lookup to get an instance of a EJB. I get this perfect, but when I tried to call a method from this EJB wich return an object (It implements Serializable) I get the next error:

(Sorry by my english)

Exception
---------
javax.servlet.ServletException: javax.ejb.EJBException: nested exception is: java.rmi.MarshalException: CORBA MARSHAL 1398079745 Maybe; nested exception is:
org.omg.CORBA.MARSHAL: vmcid: SUN minor code: 257 completed: Maybe

Cause principal
---------------
javax.ejb.EJBException: nested exception is: java.rmi.MarshalException: CORBA MARSHAL 1398079745 Maybe; nested exception is: org.omg.CORBA.MARSHAL: vmcid: SUN minor code: 257 completed: Maybe


I have using Netbeans 6.5
Glassvish v2

And I have:
- A java library with the interface of Session Bean "Service" and the bussisnes objects that implements Serializable.
- An EJB Module, with the implementations of Session Bean "Service". It EJB Module includes the above java library. This implementations have the annotations @Remote.
- A web application (client). It includes the java library and it do a look up of Session Bean "Service" and call the methods of the "Service", if the method return a bussisnes object of the java library I get the above error.

Could you help me?. If anyone need more information please tell me, thank a lot.
