Problem with importing a simple Java project on an Ejb

[momsse]

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() {
    }

    //Using Hello in parameter here ...
    public Address(Hello h) {
    }

    //...
}

I get the following error:

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

Thanking you in advance for your help

You have to add the 'simple jar' to your EAR file and declare it within the application.xml.

See JBoss or Sun tutorial or post application.xml and ear structure.

I solved the problem by adding the library as if it were a client module.

I don't know if it's the best solution, but at least it works.

Thank you for your help!
