com.sun.jsftemplating.util.fileStreamer.FacesStreamerContext

This class encapsulates servlet specific objects so that the {@link FileStreamer} class is not servlet-specific.

This implementation will look for the following attributes ( {@link BaseContext#setAttribute(String,Object)}):

{@link Context#CONTENT_TYPE} -- The "Content-type:" of the response.
{@link Context#CONTENT_DISPOSITION} -- Disposition of the streamed content.
{@link Context#CONTENT_FILENAME} -- Filename of the streamed content.
{@link Context#EXTENSION} -- The file extension of the response.

  // Create dummy UIViewRoot
  UIViewRoot root = new UIViewRoot();
  root.setRenderKitId("dummy");


  // Setup the FacesStreamerContext
  Context fsContext = new FacesStreamerContext(context);
  fsContext.setAttribute(Context.FILE_PATH, path);


  // Get the HttpServletResponse
  Object obj = context.getExternalContext().getResponse();
  HttpServletResponse resp = null;
  if (obj instanceof HttpServletResponse) {
      resp = (HttpServletResponse) obj;


      // We have an HttpServlet response, do some extra stuff...
      // Check the last modified time to see if we need to serve the resource
      long mod = fsContext.getContentSource().getLastModified(fsContext);
      if (mod != -1) {
    long ifModifiedSince = ((HttpServletRequest)
      context.getExternalContext().getRequest()).
      getDateHeader("If-Modified-Since");
    // Round down to the nearest second for a proper compare
