[jboss-user] [JBoss Seam] - Re: Download binary files

Hummm.

I removed the things I do not understand (as mentioned, beginRequest and endRequest). With this, I was able to remove BypassInterceptors, and without BypassInterceptors I can have injected my hibernate session.

At the first sight, it works perfectly. Of course, I don't know if I am breaking something in the interns of seam or if I am creating memory leaks or whatever.


  | @Startup
  | @Scope(ScopeType.APPLICATION)
  | @Name("dateidownload")
  | public class Dateidownload extends AbstractResource {
  |  @In
  |  Session session;
  | 
  |  @Override
  |  public void getResource(HttpServletRequest request,
  |    HttpServletResponse response) throws ServletException, IOException {
  |   // ServletLifecycle.beginRequest(request);
  |   try {
  |    String id = request.getQueryString();
  |    Anhang_Dokument ad = (Anhang_Dokument) session.get(
  |      Anhang_Dokument.class, Long.parseLong(id));
  |    if (ad == null)
  |     throw new ObjectNotFoundException(id);
  |    response.setHeader("Cache-Control", "no-store");
  |    response.setHeader("Pragma", "no-cache");
  |    response.setDateHeader("Expires", 0);
  |    response.setContentType(ad.getDatei().getMimeType());
  |    response.getOutputStream().write(ad.getDatei().getDaten());
  |    response.getOutputStream().flush();
  |    response.getOutputStream().close();
  |   } catch (Exception e) {
  |    response.sendError(HttpServletResponse.SC_NOT_FOUND);
  |    return;
  |   } finally {
  |    // ServletLifecycle.endRequest(request);
  |   }
  | }
  | 
  |  @Override
  |  public String getResourcePath() {
  |   return "/download";
  |  }
  | 
  | }
  | 

There are other things in CaptchaImage I don't understand, for example the meaning of @Startup and @Install together. But as told before, I simply deleted things I did not understand, and for the moment, it works ...
