Welcome to the CometD Project, a scalable comet (server push) implementation for the web.
The CometD source code is released under the Apache 2.0 License.
cometd-archetypes - The Maven archetypes for quick application development
cometd-demo - Demo of the Java server and of the Dojo/jQuery clients
cometd-java - The Java server and java client libraries
cometd-javascript - The JavaScript (Dojo/jQuery) client libraries
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>
Issues, bugs and requests for enhancements should be filed at https://bugs.cometd.org
If you have cloned the source release, follow the instructions at https://docs.cometd.org/current/reference/#_build, or just do:
$ mvn install
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.
