The Bean is just a POJO - without any dependencies to libraries etc:



public class MessageFacade {

public String hello(){

return "Working without annotations";

}

}





You will need to specify everything in XML:

<ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee"

version = "3.1"

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/ejb-jar_3_1.xsd">

<enterprise-beans>

<session>

<ejb-name>MessageFacade</ejb-name>

<local-bean/>

<ejb-class>com.abien.patterns.business.annotationless.boundary.MessageFacade</ejb-class>

<session-type>Stateless</session-type>

</session>

</enterprise-beans>

</ejb-jar>



Now you can use already the no-interface view Bean and inject it into a servlet (JSF backing beans, interceptors, other beans):



public class FrontController extends HttpServlet {

@EJB

MessageFacade facade;

//...





With XML (ejb-jar.xml) you could develop the whole application without even having the EJB 3.X API in your classpath...

This sample was deployed as a WAR. The ejb-jar.xml has to be placed into WEB-INF.

The project (AnnotationLessEJB31) was pushed into: http://kenai.com/projects/javaee-patterns/. The code was tested with Netbeans 6.7 and Glassfish v3 Prelude. Netbeans 6.7, however, does not support EJB 3.1 directly. You will have to copy the ejb-jar.xml from src/java/conf into build/web/WEB-INF/ manually or change the ANT-script.
