おはよう！私はJavaEE 6の新人です。次のチュートリアルを使用して開始プロジェクトを作成しようとしました：Creating and Running an Application Client on the GlassFish Server。私は4つのプロジェクトを段階的に作成しました。EJB Remote Interfaceを格納するJava SEのlib、EJBモジュール、そしてそれ以外の場合はチュートリアルで説明しています。Hello World！リモートステートレスセッションBean
マイプラットフォーム：
- ディストリビュータID：Ubuntuの説明：Ubuntuの10.10リリース：10.10 コードネーム：マーベリック
- jdk1.6.0_26
- Netbean7.2
- のGlassFishサーバー（201207171143の構築） 3+
私のリモートインターフェイス
package ejb.started;
//
import javax.ejb.Remote;
//
@Remote
public interface StartedSessionBeanRemote {
String getHelloWorld();
}
その実装：
package ejb.started;
//
import javax.ejb.Stateless;
//
@Stateless(name="StartedSessionBeanRemote")
public class StartedSessionBean implements StartedSessionBeanRemote {
@Override
public String getHelloWorld() {
return ("Hello world, EJB!");
}
}
そして、クライアントコード：
package startedentappclient;
//
import ejb.started.StartedSessionBeanRemote;
import javax.ejb.EJB;
//
public class AppClientMain {
@EJB
private static StartedSessionBeanRemote startedSessionBean;
public static void main(String[] args) {
System.err.println("EJB: "+startedSessionBean.getHelloWorld());
}
}
私はリモートクライアントPROJを実行しようとすると、私は次のような出力受信：

私はその問題が何であるか推測できません。私は2番目のPCで同じプロジェクトを構築し、すべて正常に動作します。それには同じソフトウェアプラットフォームがあります。
チュートリアルには欠陥があります。彼らはエンタープライズアプリケーションを作成することを提案します。 EJBモジュールを作成するだけであれば、宣言したとおりに動作するはずです。参照：http://stackoverflow.com/questions/25828542/how-to-create-a-remote-session-ejb-from-a-client/25829907#25829907 – Thufir
