RE: Setting up Comet on Tomcat 6

[Talal Rabaa <Ta...@emergis.com>]

I appreciate your feedback, it led me to the problem.  My environment was setup using an invoker servlet.  It didn't occur to me to explicitly map the Comet servlet.  Once I made the entry in web.xml I was able to see the results you provided.

Cheers!

I took your servlet, compiled it, put it in WEB-INF/classes/testing/comet

then in web.xml I put
  <servlet>
    <servlet-name>testcomet</servlet-name>
    <servlet-class>testing.comet.CometConnection</servlet-class>
  </servlet>
 
  <servlet-mapping>
    <servlet-name>testcomet</servlet-name>
    <url-pattern>/comet</url-pattern>
  </servlet-mapping>

server.xml has
        <Connector port="8080" 
protocol="org.apache.coyote.http11.Http11NioProtocol" 
connectionTimeout="10000"
        tomcatAuthentication="false" keepaliveTimeout="5000"
        backlog="50" maxThreads="300" />


hit http://localhost:8080/comet with my browser, output is

Comet test servlet initialized.
Comet test initialized.
Received event BEGIN
