Async RESTeasy on JBAS6

osnetwork Apr 10, 2011 6:25 PM

Hello everybody,

I think that the async module of RESTeasy is not working on JBAS6. Is there some configuration changes that needs to be done in order to get it working?

I have tried Servlet3AsyncHttpRequest, JBossWebAsyncHttpRequest and JBossWebDispatcherServlet none of those works, while JBossWebDispatcherServlet was working fine on JBAS5.1.

I was wondering if I need to copy any async-http-*.jar libraries somewhere inside the JBAS or if I can leave them packed in the war file.

Thanks in advance,

Luca

Here are more details.

On the server I get:

The code that I'm trying to execute is:

          @Path("basic")
          @Produces("text/plain")
          public void getBasic(final @Suspend(100000) AsynchronousResponse response)
                              throws Exception {
                    Thread t = new Thread() {
                              @Override
                              public void run() {
                                        try {
                                                  System.out.println("STARTED!!!!");
                                                  Thread.sleep(5000);
                                                  Response jaxrs = Response.ok("basic")
                                                                      .type(MediaType.TEXT_PLAIN).build();
                                                  response.setResponse(jaxrs);
                                        } catch (Exception e) {
                                                  e.printStackTrace();
                                        }
                              }
                    };
                    t.start();
          }

What's the root cause in this case?

I'm doing a GET request to the REST resource that is supposed to answer asynchronously
