Filter data in function of the logged user

Question

Hi,
I don't and I can't use ADF security for my current project but I need an authentication system.
So I created a simple managed bean (session scope) with current user information (username, roles, ...).
The problem is that displayed data must be filtered in function of the user (and his roles).
How can I do to access my user information in my application module?
I think that the easiest solution would be to access directly my managed bean in my application module but I don't know how to do that.
As I said I can't use ADF security so I don't have access to getUserData() & getUserRoles()...
Do you have any idea?
Thanks in advance!

There is one possibility of which I can think of.
1 Create a package in your database: e.g.
create or replace package PCK_LOGIN
as
c_user_id varchar2(50);
procedure set_user_id(pi_user_id in varchar2(50)
as
begin
c_user_id := pi_user_id;
end;
function get_user_id
as
begin
return c_user_id;
end;
end;Then create a method in your application module to call set_user_id.
After you have the user id in your bean you need to call this method.
Now the user id is known in the database (this is session dependent!)
and you can user M_LOGIN.get_user_id in your views and view objects.
To access the application module in your bean you can use the code
    private AppModule getAppModule(String dataControl) {
        // 1. Access the FacesContext
        FacesContext fc = FacesContext.getCurrentInstance();
        // 2. Create value binding for the #{data} EL expression
        ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
        // 3. Evaluate the value binding, casting the result to BindingContext
        BindingContext bc = (BindingContext)vb.getValue(fc);
        // 4. Find the data control by name from the binding context
        DCDataControl dc = bc.findDataControl(dataControl);
        // 5. Access the application module data provider
        ApplicationModule am = (ApplicationModule)dc.getDataProvider();
        // 6. Cast the ApplicationModule to its client interface
        AppModule appMod = (AppModule)am;
        return appMod;
    }You can also do a variation without the database. You can also just set a private variable in your application module in the same way as described above.
