</f:view>

</html>

solutions:

1.project-->right click->properties->project Facets->add JavaServer Faces.

then refresh and rebuild project again and again until the errors disappear.

2.changed your jsp page to xhtml,then modified the page taglib using the below snap:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"

      xmlns:h="http://java.sun.com/jsf/html"

      xmlns:f="http://java.sun.com/jsf/core"

      xmlns:ui="http://java.sun.com/jsf/facelets">

done;
