Question

我是学习EJB的初学者。我想在netbean 6.7中测试非常小的ejb应用程序。代码如下

package jeenptbeans;
import javax.ejb.Remote;
@Remote
public interface NewSessionRemote {
    public String getEchoString(String clientString);

}

package jeenptbeans;
import javax.ejb.Stateless;

@Stateless
public class NewSessionBean implements NewSessionRemote, NewSessionLocal {

 public String getEchoString(String clientString) {
return clientString + " - from session bean";
}
 public String getdisString(String clientString) {
return clientString + " - from session bean";
}

所以，我创建了File - ＆gt; New Project - ＆gt; EJB模块。右键单击项目并选择New - ＆gt; Session bean并添加上面的代码。但是我运行这个项目，“build successfully”消息显示。所以我想用客户端应用程序测试这个bean。所以我制作了“企业应用程序客户端”应用程序，并按如下方式添加了ejb。

import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ejb.EJB;
import javax.naming.NamingException;
import jeenptbeans.NewSessionRemote;
import javax.naming.InitialContext;
import jeenptbeans.NewSessionBean;

public class Main {
    @EJB
    private static NewSessionRemote newSessionBean;
   public static void main(String[] args) {
        try {
              InitialContext ctx = new InitialContext();
             newSessionBean = (NewSessionBean)ctx.lookup(NewSessionBean.class.getName());

            for (int i = 0; i < args.length; i++) {
            String returnedString = newSessionBean.getEchoString(args[i]);
            System.out.println("sent string: " + args[i] +
            ", received string: " + returnedString);
            }
        } catch (NamingException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }
    }

}

但是当我运行这个客户端应用程序时，我遇到了以下例外情况。

请帮帮我。这是对还是错，使“企业应用程序客户端”应用程序测试简单的会话bean？我也不知道在哪里添加main函数的参数。要使用netbean 6.7测试这个非常简单的ejb，请教我遵循的步骤。非常感谢。

NetBeans非常好的一个领域是Documentation, Training & Support（和Community Docs）。在这里，我建议检查Creating EJB3 Sessions Beans using Netbeans 6.1 and Glassfish（如页面底部所示，“使用 NetBeans 6.0,6.5,6.1,6.7,6.7.1 ”< / em>的）。

关于Enterprise Application Client功能，应该可以，但我没有任何使用经验（我想知道这样的项目是如何在NetBeans之外工作的）。我只是使用标准的Java客户端。

如何在netbean6.7中开发和运行ejb？
