在Netbeans中运行使用EJB的测试

Question

我正在NetBeans中使用EJB和Glassfish开发客户机-服务器应用程序。我在客户机上实现了一个使用会话Bean的方法。我已经尝试了从主调用方法的方法，它的工作。现在我试着在测试用例中测试方法的行为。Netbeans迫使我将JUnit测试用例放在test Packages文件夹中。运行测试会抛出以下异常:

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
java.lang.RuntimeException: 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

at javax.naming.InitialContext.lookup(InitialContext.java:411)
at GestoreAccountLocale.GestoreAccountLocale.lookupGestoreAccountRemotoRemote(GestoreAccountLocale.java:144)    

这是我想测试的客户端方法'registrazione':

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);
    }
}

请注意，从源包中的main调用的相同方法不会抛出此异常，并且工作正常。下面是代码:

public class Main {
    public static void main(String[] args) throws VincoliInputException, RegistrazioneException, CategoriaGiaEsistenteException {
         GestoreAccountLocale.registrazione("user123", "passw123", "John", "Doe", "[e-mail]", new Date());
    } 
}    

我想这是一个从应用程序客户端的Test Packages文件夹中调用Session Bean的问题。有解决这个问题的办法吗?由于

当您在应用服务器外部使用new InitialContext()创建InitialContext时，它期望根据您的应用服务器配置以下属性:

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)
您可以将它们指定为系统属性或在类路径中的jndi.properties中。
