Simple Example of JSF and EJB 3.1

This is a very simple example of a JSF 2.0 managed bean invoking EJB 3.1 local singleton EJB. Everything is packaged into a test.war file, and deployed to GlassFish.

test.war consists of 4 entries:

WEB-INF/classes/test/HelloEJB.class
WEB-INF/classes/test/HelloJSFBean.class
WEB-INF/web.xml
index.xhtml

index.xhtml page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:h="http://java.sun.com/jsf/html">
<ui:composition>
 <h:head>
     <h1><h:outputText value="jsf-ejb example" /></h1>
 </h:head>

 <h:body>
     <h:form id="form">
         <h:outputLabel value="helloEJB returned message: "/>
         <h:outputText  value="#{HelloJSFBean.message}"/>
     </h:form>
 </h:body>
</ui:composition>
</html>

HelloJSFBean managed bean:

package test;
import javax.faces.bean.*;
import javax.ejb.*;

@ManagedBean(name="HelloJSFBean")
@RequestScoped
public class HelloJSFBean implements java.io.Serializable {
 @EJB
 private HelloEJB helloEJB;

 public String getMessage() {
     return helloEJB.hello();
 }
}

HelloEJB singleton bean:

package test;
import javax.ejb.*;

@Singleton
public class HelloEJB {
 public String hello() {
     return "Hello from " + this;
 }
}

web.xml:

<web-app 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"
   version="3.0">
<servlet>
 <servlet-name>Faces Servlet</servlet-name>
 <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
 <url-pattern>/faces/*</url-pattern>
</servlet-mapping>
</web-app>

To run the webapp:

curl http://localhost:8080/test/faces/index.xhtml

helloEJB returned message: Hello from test.HelloEJB@1326d2fe
