Embedding jBoss EJB in a managed JSF 2.0 bean running in tomcat web application

Question

I searched for a while, and I cannot find a solution, the problem is this:

• I have an EJB3 application deployed in jBoss 6.0 with ejb removed.
• I have a web application (JSF 2.0) deployed in Tomcat 6.0.

I do not want to run the tomcat web application in jBoss, its application is running tomcat, and the architecture should remain the same.

I don’t want to search for EJB manually (I want to insert it), in other words, I don’t want to do it like this:

Properties properties = new Properties(); properties.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); properties.setProperty("java.naming.provider.url", "jnp://localhost:1099"); properties.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); Context c = new InitialContext(); MySB mySB = (MySB) c.lookup("MySB/remote"); 

I need to inject jBoss EJB into managed beans in a Tomcat application like

 @EJB(name="MySB/remote") protected MySB mySB; 

as if MySB/remote is in the local tomcat JNDI, but in fact it is being viewed from jBoss JNDI backstage.

perhaps?

You can do this using CDI. Unfortunately, CDI support does not come with a standard servlet engine like Tomcat, so if you want to deploy a JSF application that uses CDI annotations, you need to get an implementation of the CDI specification. The reference implementation of JSR 299 is known as Weld . To install it you need:

1) put weld-servlet.jar in the WEB-INF\lib folder of your JSF application

2) add the following listener definition in web.xml :

 <listener> <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class> </listener> 

3) add an empty beans.xml file along with the web.xml and faces-config.xml file in the application’s WEB-INF folder:

 <?xml version="1.0" encoding="UTF-8"?> <beans 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/beans_1_0.xsd"> </beans> 

Finally, you need @Inject your EJB in managed beans.

Hope this helps.
