Read HttpSession Variables in Multiples Projects...

Question

I'm using JDeveloper 9.0.3 with BC4J+UIXML, and I have the problem:
One session varible using HttpSession created in the Project "A", don't be used in Classes of Project "B", after deploy processes.
Example:
Project "A"
file1.uix - invoking Java Class FunSessionVar (create session variables and call file2.uix in Project "B"):
import oracle.cabo.servlet.BajaContext;
import oracle.cabo.servlet.Page;
import oracle.cabo.servlet.event.PageEvent;
import oracle.cabo.servlet.event.EventResult;
import oracle.cabo.data.jbo.servlet.bind.*;
import oracle.cabo.ui.data.BoundValue;
import oracle.cabo.ui.data.DataBoundValue;
import oracle.cabo.servlet.util.RedirectUtils;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
public class FunSessionVar
public static EventResult FunPrepSessionVar(BajaContext context
,Page page
,PageEvent event) throws Throwable
     HttpServletRequest req = context.getServletRequest();
     HttpSession sess = req.getSession(true);
     sess.setAttribute("CodPessoaEscola", event.getParameter("CodPessoaEscola"));
     sess.setAttribute("DspNomEscola", event.getParameter("DspNomEscola"));
     Page browsePage = new Page(page, "../ProjectB/file2.uix");
     return new EventResult(RedirectUtils.getRedirectPage(context, browsePage));
Project "B"
file2.uix - have a "null" event invoking Java Class FunReadSessionVar (read session variables and set View Object Query):
import oracle.jbo.ViewObject;
import oracle.cabo.servlet.BajaContext;
import oracle.cabo.servlet.Page;
import oracle.cabo.servlet.event.PageEvent;
import oracle.cabo.servlet.event.EventResult;
import oracle.cabo.data.jbo.servlet.bind.*;
import oracle.cabo.ui.data.BoundValue;
import oracle.cabo.ui.data.DataBoundValue;
import oracle.cabo.servlet.util.RedirectUtils;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
public class FunReadSessionVar
public static EventResult FunPrepReadSessionVar(BajaContext context
,Page page
,PageEvent event) throws Throwable
     HttpServletRequest req = context.getServletRequest();
     HttpSession sess = req.getSession(true);
     String valor1 = sess.getAttribute("CodPessoaEscola");
     String valor2 = sess.getAttribute("DspNomEscola");
     ViewObject view = ServletBindingUtils.getViewObject(context);
     view.setWhereClauseParam(0,valor1);
     view.setWhereClauseParam(1,valor2);
     view.executeQuery();
     return new EventResult(page);
Well, the method [b]sess.getAttribute("CodPessoaEscola"); return null value, but the correct value passed in
FunSessionVar (Project "A") is equal "180".
Any body have a solution for this problem ?

John, thanks for your help...
The event parameters does not have null values, because if I write this command in the Pages of Project "A", the show values are correct:
<flowLayout>
<contents>
CodPessoaEscola:
<styledText data:text="text@getCodPessoaEscola" />
</contents>
</flowLayout>
(The Data Provider return HttpSession variable of CodPessoaEscola).
May be HttpSession variables have restrict scope inside Project ? Does the web.xml file have properties to configurations of this feature, before make deploy ?
Thanks,
Danilo
