美好的一天！我是JavaEE 6中的新成員。我嘗試使用以下教程創建一個已啓動的項目：Creating and Running an Application Client on the GlassFish Server。我一步一步地創建了四個項目：JavaSE lib來存儲EJB遠程接口，一個EJB模塊，以及本教程中介紹的其他方法。Hello World！與遠程無狀態會話Bean
我的平臺：
- 經銷商ID：Ubuntu的說明：Ubuntu的10.10發行版：10.10 代號：特立獨行
- jdk1.6.0_26
- Netbean7.2（構建201207171143）
- GlassFish應用服務器3+
我的遠程接口
package ejb.started;
//
import javax.ejb.Remote;
//
@Remote
public interface StartedSessionBeanRemote {
String getHelloWorld();
}
它的實現：
package ejb.started;
//
import javax.ejb.Stateless;
//
@Stateless(name="StartedSessionBeanRemote")
public class StartedSessionBean implements StartedSessionBeanRemote {
@Override
public String getHelloWorld() {
return ("Hello world, EJB!");
}
}
而且客戶端代碼：
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());
}
}
當我嘗試運行遠程客戶端凸出，我收到以下輸出：

我不能認爲是什麼問題。我在第二臺個人電腦上建立了相同的項目，併成功完成所有工作那個擁有相同的軟件平臺。
我發現教程有瑕疵。他們建議做一個企業應用程序。相反，如果您只製作一個EJB模塊，它應該像宣傳的那樣工作。請參閱：http://stackoverflow.com/questions/25828542/how-to-create-a-remote-session-ejb-from-a-client/25829907#25829907 – Thufir
