Examples with PortletRequestDispatcher javax.portlet.PortletRequestDispatcher used on opensource projects

Example 1 with PortletRequestDispatcher

use of javax.portlet.PortletRequestDispatcher in project acs-community-packaging by Alfresco.

the class AlfrescoFacesPortlet method handleError.

/**
 * Handles errors that occur during a render request
 */
private void handleError(RenderRequest request, RenderResponse response, Throwable error) throws PortletException, IOException {
    // get the error bean from the session and set the error that occurred.
    PortletSession session = request.getPortletSession();

    if (errorBean == null) {

        session.setAttribute(ErrorBean.ERROR_BEAN_NAME, errorBean, PortletSession.PORTLET_SCOPE);
    }
    errorBean.setLastError(error);
    // if the faces context is available set the current view to the browse page
    // so that the error page goes back to the application (rather than going back
    // to the same page which just throws the error again meaning we can never leave
    // the error page)
    FacesContext context = FacesContext.getCurrentInstance();
    if (context != null) {
        ViewHandler viewHandler = context.getApplication().getViewHandler();

    // get the error page and include that instead
    String errorPage = getErrorPage();
