Redirecting url through method call

Question

I am using Jdev Build JDEVADF_11.1.1.6.0_GENERIC_111205.1733.6192.1 for my development.
I have to redirect to different url based upon some conditions in my logic.
but when I am redirecting I am getting Response already commited error..
I am using below code to redirect..
public void redirectToLandingPage() {
FacesContext fctx = FacesContext.getCurrentInstance();
// ExternalContext ectx = fctx.getExternalContext();
String currentViewId =
FacesContext.getCurrentInstance().getViewRoot().getViewId();
String viewId = "/oracle/webcenter/portalapp/pages/LandingPage.jspx";
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContext();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
String url = ectx.getRequestContextPath()+"/"+viewId;
try {
response.sendRedirect(url);
fctx.responseComplete();
} catch (Exception ex) {
ex.printStackTrace();
I also tried
public void redirectToLandingPage() {
FacesContext fctx = FacesContext.getCurrentInstance();
ExternalContext ectx = fctx.getExternalContext();
String currentViewId =
FacesContext.getCurrentInstance().getViewRoot().getViewId();
String viewId = "/oracle/webcenter/portalapp/pages/LandingPage.jspx";
ControllerContext controllerCtx = null;
controllerCtx = ControllerContext.getInstance();
String activityURL = controllerCtx.getGlobalViewActivityURL(viewId);
try {
ectx.redirect(activityURL);
} catch (IOException e) {
e.printStackTrace();
but getting same error.
any help would be appricated.
Regards,
Kiran.

This is what I use after logout, in order to sent user to login page :
    FacesContext context = FacesContext.getCurrentInstance();
    HttpServletRequest request = (HttpServletRequest)context.getExternalContext().getRequest();
    HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();  
    String url = request.getRequestURL().toString();
    StringBuffer sb = new StringBuffer(url);
    int indexOfRequestURI = url.indexOf(request.getRequestURI());
    sb = sb.replace(indexOfRequestURI, url.length(), request.getContextPath() + request.getServletPath() + "/login.jspx");
    String redirectUrl = response.encodeRedirectURL(sb.toString());
    response.sendRedirect(redirectUrl);
    context.responseComplete();
