Runnig tests that use EJB in Netbeans

Question

I'm developing a client-server application using EJB and Glassfish in NetBeans. I've implemented a method on the client that uses a Session Bean. I've tried the method calling the method from the main and it works. Now I was trying to test the behavior of the method in a test case. Netbeans force me to put the JUnit test case in the Test Packages folder. Running the test throws the following exception:

Testcase: test21(registrazioneTest): Caused an ERROR
javax.naming.NoInitialContextException: Need to specify class name in environment or system  property, or as an applet parameter, or in an application resource file:     java.naming.factory.initial

Here is the client method 'registrazione' that i want to test:

public static void registrazione(String username, String password, String nome, String cognome, String email, Date dataNascita) throws VincoliInputException, RegistrazioneException {
    checkUsername(username);
    checkPassword(password);
    checkNome(nome);
    checkCognome(cognome);
    checkEmail(email);
    checkData(dataNascita);

    GestoreAccountRemotoRemote gestore = lookupGestoreAccountRemotoRemote(); 

    if(! gestore.verificaDatiAccount(username,password,nome,cognome,email,"dataNascita")) {
         System.out.println("Errore nella registrazione");
         throw new RegistrazioneException();
     }

    System.out.println("Registrazione avvenuta con successo.");
} 

private static GestoreAccountRemotoRemote lookupGestoreAccountRemotoRemote() {
    try {
        Context c = new InitialContext();
        //return (GestoreAccountRemotoRemote) c.lookup("java:global/ServerMDB/ServerMDB-ejb/GestoreAccountRemoto");
        return (GestoreAccountRemotoRemote) c.lookup("java:global/ServerMDB/ServerMDB-ejb/GestoreAccountRemoto!GestoreAccountRemoto.GestoreAccountRemotoRemote");
    } catch (NamingException ne) {
        //Logger.getLogger(getClass().getName()).log(Level.SEVERE, "exception caught", ne);
        throw new RuntimeException(ne);
    }
}

Note that the same method called from the main in the sources packages doesn't throws this exception and works fine. Here's the code:

public class Main {

    public static void main(String[] args) throws VincoliInputException, RegistrazioneException, CategoriaGiaEsistenteException {
         GestoreAccountLocale.registrazione("user123", "passw123", "John", "Doe", "johndoe@gmail.com", new Date());
    } 
}

I suppose it's a problem of calling the Session Bean from the Test Packages folder in the application client. Any idea for solving this problem? Thanks

Can you please explain what "calling the method from the main" mean? Is this call made in the application server? — Priyesh, May 13 '14 at 15:57
I call the method 'registrazione' in the the main method in a class that is located in the Source Package of the application client. So we success in using the session bean outside the application server, without specifying the jndi properties. I don't undestand why if I use the same code in a test class in test package it doesn't work. — fnlls10, May 13 '14 at 17:31
@Priyesh I updated the post with the main method code. The main and the 'registrazione' test are located in the application client. Here's the project explorer. http://imagizer.imageshack.us/a/img837/1621/a21c.png — fnlls10, May 14 '14 at 10:32

When you create an InitialContext using new InitialContext() outside the application server, it expects the following properties to be configured based on your application server:

java.naming.factory.initial (Factory specific to your application server)
java.naming.provider.url (URL of the application server e.g. t3://localhost:7003)
java.naming.security.principal (username)
java.naming.security.credentials (password)

(http://docs.oracle.com/javase/7/docs/api/javax/naming/Context.html#INITIAL_CONTEXT_FACTORY)
You can specify these as System properties or in a jndi.properties in your classpath.
