Java EE (Java Enterprise Edition) General Discussion

I developed a simple J2EE Project using Netbeans 5.5.




I have the following EJB's:

- ShoppingCartBean.java (Stateful Session Bean)
- ShoppingCartLocal.java

- Product.java (Entity Bean)
- ProductFacade.java
- ProductFacadeLocal.java





The ShoppingCartBean.java has the basic structure:


@Stateful
public class ShoppingCartBean implements ShoppingCartLocal {

@EJB
private ProductFacadeLocal productFacade;

...

public void addProduct( String id ) {
Product product = productFacade.find( id );
...
}

...

}




HOWEVER, when I try and run the app, I get the following error:

Deploying application in domain failed; Error loading deployment descriptors for module [help2] -- This bean [ShoppingCartBean] has no ejb reference by the name of [productFacade]





I believe that the error is caused by the file < sun-ejb-jar.xml >. Here are the contents of that file:


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 9.0 EJB 3.0//EN" "http://www.sun.com/software/appserver/dtds/sun-ejb-jar_3_0-0.dtd">
<sun-ejb-jar>
<enterprise-beans>
<ejb>
<ejb-name>ShoppingCartBean</ejb-name>
<ejb-ref>
<ejb-ref-name>productFacade</ejb-ref-name>
<jndi-name>ejb/productFacade</jndi-name>
</ejb-ref>
</ejb>
</enterprise-beans>
</sun-ejb-jar>








CAN ANYBODY PLEASE HELP???





If you're really good with J2EE, here's the error stack trace:
