Expose ADF-BC as ejb and use it in UI from the datacontroller

Question

Hi Experts.
Here i am looking forward some experts view and guidelines on this deployment architecture question. Currently i have deploped one ADF Web fusion application which has ADF-BC and web. In that web project datacontroller side i can be able to see the view object instances under each business service. Also the web has some UI bindings too. Now the application is working fine fine on one weblogic instance.
question1) Can i deploy this above project into two weblogic instances one with ADF-BC model ( if yes how to deploy that alone) and the other web into the another instance. ( If yes can to configure the project)
question 2) Now can i expose the ADF-BC as ejb and use it in the same way in the web (like drag and drop from the Data controller). ? I tried the option expose the ADF-BC as ejb In this case if the VO instance access methods are not exposed. So how can i access them in the UI? For example, assume if we have 2 view object EmployeeView and DepartmentView in the application module, then after immediately create the AM, the datacontrol shows the view object instances name like EmployeeView1, DepartmentView1 and also in the web we just drag and drop to create appropriate UI. This is fine. Now i create the ejb based on the AM. In the Remote interface i have the
void removeEntity(Object entityDTO)
method. If i look at the datacontrol section still the data controls remains same. I think this datacontrol still shows the ADF-BC direct connectivity. If i try to create the new ejb data control which points to the same AM ejb for web, then i couldn't see the above view instance name called EmployeeView1, DepartmentView1, where i can drag and drop in the UI.
I can only see methods like EJBHome etc.....
So this means i cannot use the Exposed EJB from the ADF-BC Application Module to drag and drop in UI like the ADF-BC direct unless we explicitly create the view access methods in the interface. Am i correct?
Or still am i getting the wrong assumption.
Much appreciated if u point some code to understand this.

Thanks for the reply.
Basically we have found the way to expose the ADFBC as ejb and use it for data binding in the UI. I will update this thread soon about our finding. But now i have an architecture question, can we deploy as 3-tier deployment for ADF-BC using the exposed ejb interface? Because i am worrying we might run into some ADF issue in furture if we move this path. Oracle gurus please share your ideas or thoughts.
