RESTEasy is preconfigured and completely integrated with JBoss 6-M4 and higher. You can use it with EJB and CDI and you can rely completely on JBoss for scanning for your JAX-RS services and deploying them. All you have to provide is your JAX-RS service classes packaged within a WAR either as POJOs, CDI beans, or EJBs and provide an empty web.xml file as follows:

        
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
</web-app>
