Problem with post request parameters in servlets
I'm trying to get the response from servlets by sending post request with
parameters to the servlets. But despite of servlets response, I'm getting
blank output. Firebug showing blank response. But If I send the post request
without request parameter, or at the time refreshing a page, I get the
response.
I've implement CometProcessor interface in servlets, and I'm using Tomcat 6
as a webserver. May I know the reason of the problem?
This is how I'm trying to respond to the client request, I've already
enabled NIO connector in server.xml file.
public void event(CometEvent event)
throws IOException, ServletException {
HttpServletRequest request = event.getHttpServletRequest();
HttpServletResponse response = event.getHttpServletResponse();
String username = request.getParameter("username");
String password = request.getParameter("password");
if (event.getEventType() == CometEvent.EventType.BEGIN) {
PrintWriter out = response.getWriter();
out.println("HELLO");
out.flush();
}
}

I'm not sure it's legal to use request.getParameter() in a Comet BEGIN
request.
Given that Comet is supposed to be built around asynchronous I/O, I
suspect that you'll have to read your own parameters if you want to do
things in the BEGIN event.
See this message in the archives for some more coherent thoughts:

If I don't use request.getParameter() method despite of making same request
with parameters in my servlets code, I'm not getting any blank response in
my browser.
This is how I set connector tag in server.xml file:
<Connector connectionTimeout="20000" port="8081"
protocol="org.apache.coyote.http11.Http11NioProtocol" redirectPort="8443"/>

When you say "without request parameter[s]", do you mean that you are
sending a POST with no /GET/ parameters? Perhaps you could give us a
more complete example.

Please post your <Connector> configuration.
