A chat room is a would require some machine to store the conversations, topics, user information, etc. and some mechanism for users to access these items, therefore you probably need a server of some sort and using an application server should save you development time to concentrate on the application.
I believe Sun has a server you can use for development, but not deployment. If not Try Resin or IBM for their low-end, "free" or developmental servers. Regarding certification: Sun will definitely supply the certifications you desire. For Java Certifications, see http://suned.sun.com/US/certification/java/certification_details.html. If you master the Pet Store sample application and manage to develop and deploy the application he mentioned, you will have the most of the knowledge. Two additional areas covered are UML and GOF Patterns (Not Java Core Patterns), so you will need more knowledge than is normally acquired by being an excellent server-side developer to acquire the certification. The book "Designing Enterprise Applications with the Java 2 Platform, Enterprise Edition" (Second Edition (or later)) should be located and matched to the version of the Pet Store application you are using. The Pet Store application is available for download at http://developer.java.sun.com/developer/releases/petstore/petstore1_1_2.html and browsing (oft times better) at http://java.sun.com/blueprints/code/jps11/docs/index.html. Read the assignments and test objectives very, very carefully. BTW: You will need to submit UML class, component, and interaction (sequence) diagrams when you work the assignment. I used Objecteering UML Modeler to create mine. The offer a 90 day trail of the personal edition at: http://www.objecteering.com/.
