Obtaining FacesContext within xhtml view with JSF

Question

I am trying to migrate an application from RichFaces to PrimeFaces 5.0 and upgrade JSF 1.2 to JSF 2.2. Earlier we had .jsp pages which contained below piece of code.

<%
    FacesContext fc = FacesContext.getCurrentInstance();
    Login login = (Login) fc.getELContext().getELResolver().getValue(fc.getELContext(), null, "login");
    if (null == login.getEmailAddress()) {
        response.sendRedirect("./");
    }

%>

Now we changed every .jsp page to .xhtml and as expected the above piece of code would not fit in the xhtml view. I tried searching replacement for the above functionality in view but unfortunately could not find anything regarding same. I also tried to put the above line of code within <!CDATA, [not sure whether its a right way], as below:

<![CDATA[
<%
     FacesContext fc = FacesContext.getCurrentInstance();
     Login login = (Login)fc.getELContext().getELResolver().getValue(fc.getELContext(), null, "login");
     if (null == login.getEmailAddress()) {
         response.sendRedirect("./");
     }
%>       
]]>

and as expected that didn't even work well.

How else I would be able to achieve this within xhtml? Will this be possible or should I be going for some other way to do this?

Note - The application is a Single Page Application

@JasperdeVries That really helped much bro. Would you like to add it as answer? Or will be closing this question as possible duplicate.. :) — Guruprasad J Rao, May 19 '17 at 08:12
@JasperdeVries I agree.. Thanks much once again.. :) Have a great time.. :) — Guruprasad J Rao, May 19 '17 at 08:14
@JasperdeVries Yea I do bro.. But due to some materialize-theme selection for the application, I had made lot of changes editing `Primefaces 5.0.jar`, before knowing the existence of `Primefaces 6.x`. Since, the duration is very less for delivery of 1st phase, I was not able to upgrade this. Hopefully, will upgrade in future.. :) — Guruprasad J Rao, May 19 '17 at 08:21
