Example 1 with PortletRequestAttributes

use of org.springframework.web.portlet.context.PortletRequestAttributes in project uPortal by Jasig.

the class PortalWebUtils method currentRequestContextPath.

/**
 * Get the request context path from the current request. Copes with both HttpServletRequest and
 * PortletRequest and so usable when handling Spring-processed Servlet or Portlet requests.
 * Requires that Spring have bound the request, as in the case of dispatcher servlet or portlet
 * or when the binding filter or listener is active. This should be the case for all requests in
 * the uPortal framework and framework portlets.
 *
 * @return request.getContextPath() for the relevant servlet or portlet request
 * @throws IllegalStateException if the request is not Spring-bound or is neither Servlet nor
 *     Portlet flavored
