我正在使用 NetBeans 中的 EJB 和 Glassfish 开发客户端-服务器应用程序。我已经在使用会话 Bean 的客户端上实现了一个方法。我已经尝试过从 main 调用该方法的方法，它可以工作。现在我试图在测试用例中测试该方法的行为。Netbeans 强迫我将 JUnit 测试用例放在 Test Packages 文件夹中。运行测试会引发以下异常：

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

Caused by: 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)

这是我要测试的客户端方法“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引发此异常并且工作正常。这是代码：

public class Main {

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

我想这是从应用程序客户端的测试包文件夹中调用会话 Bean 的问题。有解决这个问题的想法吗？谢谢

当您使用应用程序服务器外部创建 InitialContext 时new InitialContext()，它需要根据您的应用程序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 )
您可以将这些指定为系统属性或jndi.properties在您的类路径中。
