In this edition, I am explaining, how to write a simple IM server using SailFin CAFE.

If you have read my earlier blogs on SailFin CAFE (here and here) then there is nothing additional need to be done!. The same applications that supports 2-party calls or Conference application are already capable of handling IM between two users.

package my.test;
@org.glassfish.cafe.api.bean.CommunicationBean
public class YourCommunicationPOJO {
}

That means the above code will support IM also, apart from supporting 2-party calls.

Here are the steps to run this application.

Now your application is ready to test against any SIP phones. To use X-Lite sip phone, follow the steps below.
