I'm not sure about these memory things, but I'm using default setting of glassfish 2 (glassfish-installer-v2-b58.jar, downloaded from this page http://dlc.sun.com.edgesuite.net/javaee5/promoted/Linux/) on Ubuntu 9.10. > > return new StreamingResolution("application/octet-stream") { > protected void stream(HttpServletResponse response) throws >Exception > { > String sp = File.separator; > InputStream in = new >FileInputStream(video.getLocation() + sp + video.getFilename()); > try > { > OutputStream out = >response.getOutputStream(); > > byte[] buf = new byte[1024 * 65]; > int size = 0; > > while ((size = in.read(buf)) > 0) > out.write(buf, 0, size); > } > finally > { > in.close(); > } > } > }.setFilename(video.getOriginalFilename()); > } This resolution is working like the other ones. I tried this one also: http://www.stripesframework.org/display/stripes/AJAX#AJAX-MoreEfficientRealTimeStreaming But the problem is still there. Maybe the best way to do this thing is put files somewhere here glassfish/domains/domain1/docroot and send direct links to clients.
