First Steps

I recomend to take a look at the demo at first.

Just deploy the demo project in any AS with eclipse or your IDE of choice, and try out some features!

Extended Demo - DEPRECATED

After you played around with the demo you can start to use it immediatly or you can take a look at the extended demo.

In the extended demo a real database is used via JPA.

Because of that you need to create a datasource (commentboxDS) in the configs of your AS or rename the used datasource to one of yours (in persistence.xml).

Then deploy the demo project in any AS with eclipse or your IDE of choice.

NOTE: The Extended Demo is not maintained anymore, i will remove it in the future.

Notice for JBoss usage

In case you use JBoss and want to use the live features you need to adjust the standalone.xml to support atmosphere:

change the line:

<subsystem xmlns="urn:jboss:domain:web:1.1" native="false" [...]>


<subsystem xmlns="urn:jboss:domain:web:1.1" native="true" [...]>

Why should i use it, i could use some external chat service?

  • You keep your data where it belongs, on your server !
  • Also you can (and are allowed to) make modifications to adapt to your special needs.
  • You can connect this component to your own user-system and your users don't need to have an account on your site and an additional account for the external system.
