Question

I am trying to implement a Comet process.

Tomcat 6.0.36

Red Hat Enterprise Linux Server release 6.2 (Santiago)

Java 7u11 (32 bit)

I have implemented CometProcessor. I am using the NIO connector.
When I try the servlet I get: HTTP method GET is not supported by this URL.
The other topics I have found on this matter advise people to make sure they are using the NIO connector. I have. I have also seen recommendations to make sure the catalina.jar was not packaged with the web app. I have checked that also.

Am I doing something wrong?

Thanks!

Code snippet:

public class ConsolidatedActionCenterPush extends HttpServlet  implements CometProcessor,CAC{

  private static MessageSender messageSender = null;
  private static final Integer TIMEOUT = 600 * 1000;

  @Override
  public void destroy() {
    messageSender.stop();
    messageSender = null;
  }

  @Override
  public void init() throws ServletException {
    messageSender = new MessageSender();
    messageSender.start();

  }


  @Override
  public void event(final CometEvent event) throws IOException, ServletException {
    HttpServletRequest request = event.getHttpServletRequest();
    HttpServletResponse response = event.getHttpServletResponse();

 ........

}

I solved it. I was using the invoker servlet because we have a lot of un-mapped servlets. Removing the invoker servlet fixed the comet process.
