Re: [Php-java-bridge-users] Jetty 15 Second delay (15000 ms), Tomcat OK

[<php...@li...>]

The problem is that jetty doesn't flush the response buffer. In pseudo code:

protected void doPut (HttpServletRequest req, HttpServletResponse res) {

   res.getOutputStream().write(1);
   res.setContentLength(1);

   try {res.flushBuffer(); } catch (Exception t) {t.printStackTrace(); }
   try {resOut.close(); } catch (Exception t) {t.printStackTrace(t);}
   // response must be flushed right here, not at the end of the
service() routine

   Thread.wait(15000);

 }


> Connection:keep-alive

It's a HTTP/1.0 request. If jetty sets keep-alive for a HTTP/1.0
request, we've found another bug, I think.


BTW: Jetty contains another serious bug:

  requestDispatcher.include(req, res);

If req is an instance of HttpServletRequestWrapper, jetty tries to
find the original request in the thread context. This fails if the
current thread is not a servlet thread. You can verify this bug by
clicking on the jsr223.jsp example of the JavaBridge.war; jetty
crashes with a NullPointerException.
