Running the CometD Demo
If you have downloaded the release bundle, then the CometD is already built for you.
To run the demonstration with Maven, unzip the release bundle and execute:
$ cd cometd-demo
$ mvn jetty:run
then point your browser at http://localhost:8080
Alternately you can deploy the CometD demo war file into
any Servlet 2.5 or later server (e.g. jetty, tomcat, glassfish)
with commands like:
$ cp cometd-demo/target/cometd-demo/target/cometd-demo-*.war $MY_SERVER/webapps/cometd.war
cd $MY_SERVER
<command to run my server>
Reporting Issues
Issues, bugs and requests for enhancements should be filed at https://bugs.cometd.org
Building CometD
If you have cloned the source release, follow the instructions at
https://docs.cometd.org/current/reference/#_build, or just do:
$ mvn install
Load Testing CometD
To run load testing, open two windows. In the server window run:
$ cd cometd-java/cometd-java-benchmark/cometd-java-benchmark-server/
$ mvn exec:exec
In the client window (potentially on another machine), run
$ cd cometd-java/cometd-java-benchmark/cometd-java-benchmark-client/
$ mvn exec:exec
Then follow instructions on the console to generate load.
