ADF independent transactions

Question

Hi all,
I'm trying to implement independent transactions in JSF/ADF. At the next lines I'll try to explain the process that I have followed:
- First of all we know there are two ways to obtain independent transactions (e.g. different executions of the same page). One of them is creating different BindingContexts each time we execute the page (we obtain one DataControl and consequently one transaction for each BindingContext). The other way is to generate different DataControls in a BindingContext (one transaction for each DataControl).
This is a theorical behavior and I don't know if it is possible but i tried.
- The next step is to investigate how can we do this? I have followed OTN's how to: "How to support dynamic jdbc credentials". In this example, we extend the ADFBindingFilter class and redefine any functions. I see that in doFilter fuction it creates a new BindingContext when it is necessary (only when isn't null in initializeBindingContext). If I could modify this function and control the BindingContext creation (concretely I want to create the BindingContext each time, I know it's possible it doesn't work).
Obviously, if I want to redefine initializeBindingContext function I have to redefine the function that calls it (doFilter), because this function isn't called in any other case. When I copy-paste all the function code in my new class I have a big problem:
when I make
bindingCtx.initializeSessionContext(new HttpSessionContextImpl());
developer says to me: "access not allowed to oracle.adf.model.servlet.HttpSessionContextImpl"
Due to this problem I can't redefine this functionality and I can't test if the independent transactions are possible with this method.
Any suggestion?
Thanks at all.

hi,
the
import oracle.adf.model.servlet.HttpSessionContextImpl;
statement results in:
Error(14,8): class oracle.adf.model.servlet.HttpSessionContextImpl is not public; cannot
be accessed from outside of package package servlet
Because HttpSessionContextImpl is not a public class:
class HttpSessionContextImpl implements SessionContext{...}
Hope this helps a little.
Cheers
