Basically that parameter has to be set in the PortletRequest and not in the HttpRequest. See menu.jsp fragment below: <a id="logout" href=" | <portlet:actionURL windowState="normal"> | <portlet:param name="op" value="userLogout"/> | <portlet:param name="locationURL" value="/portal/portal/default/default"/> | </portlet:actionURL>"> | Logout and return to default page | </a> The tag portlet:actionURL does the actual work.
