Invalidating the ADF session and redirecting to EBS login screen

Question

Hi ADF team,
I am developing an application which is being accessed from eBusiness Suite (EBS), using ADFX function. It has a global Logout link. When the link is clicked, two things should happen.
1. the ADF session that is running on WLS server should be killed.
2. I should be redirected to eBusiness Suite login page.
This is what I am doing and I am getting error(s).
1. Created a Container jspx page and embedded a task flow in it.
2. Embedded a jsff into task flow.
3. In JSFF created a global link called Logout.
4. Set the action property of Logout link such that it calls a function in the AMImpl. (I confirmed, the function is being called)
5. In the function invalidate the ADF session using following code.
HttpServletResponse response = ((HttpServletResponse)ADFContext.getCurrent().getEnvironment().getResponse());
HttpServletRequest request = ((HttpServletRequest)ADFContext.getCurrent().getEnvironment().getRequest());
HttpSession sessionADF = request.getSession();
sessionADF.invalidate();
return "EBSLogin";
6. Now, EBSLogin control flow leads to a URL View component that has the URL property set as "www.oracle.com".
--Using this approach I get the error: adfc-14000: view port id ****** is invalid
-----Thus need help with this error. Is there a better way to accomplish this ?? What am i doing wrong?
Also, I have a question on how to set the URL property of 'URL View' component. I set it to #{pageFlowScope.MainPageBean.testLogoutURL}. testLogoutURL is a function that returns string. But I do get an error at run time, mentioning that the property cannot be NULL. Thus seems like the way I am doing it is not totally correct. Please advice.
Thanks & Regards,
Anoop

on top of my head
        FacesContext fc = FacesContext.getCurrentInstance();
        ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
        HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
        HttpSession session = (HttpSession)ectx.getSession(false);
        String redirectURL = (String)session.getAttribute("ebizRedirectUrl");
        if(redirectURL!=null){
          int oa_html = redirectURL.indexOf("OA_HTML");
          finalRedirectURL = redirectURL.substring(0, oa_html);
          finalRedirectURL = finalRedirectURL + "oa_servlets/AppsLogin";
        if (session != null)
        session.invalidate();
        try {
            response.sendRedirect(finalRedirectURL);
            fc.responseComplete();
        } catch (IOException e) {
            e.printStackTrace();
        }
