Hello and happy new year,

Please excuse me for my English (i am French).

I'm new to JBoss (AS version 4.4 GA), I work on a project with EJB 3.0, and am having a problem to import a project (a simple java project) in my EJB:

My project contains an EJB module:
- DemoEJB
an WAR:
- DemoWAR
and an EAR that includes them:
-DemoEAR

I want to use a Java project that contains the example for this simple class:

public class Hello {
 
    public String hello(){
     return "Hello";
    }
}




When I made it like that:

@Entity
 
@Table(name = "addresses")
 
public class Address implements Serializable {
 
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int ID;
 
    private String name;
 
    public Address() {
    }
 
    public Address(Hello h) {
 
    }
 
    //...
 
}



I get the following error:

18:40:37,464 ERROR [URLDeploymentScanner] Incomplete Deployment listing:
