问题描述

美好的一天！我是JavaEE 6中的新成员。我尝试使用以下教程创建一个已启动的项目：在GlassFish服务器上创建和运行应用程序客户端。我一步一步地创建了四个项目：JavaSE lib来存储EJB远程接口，一个EJB模块，以及本教程中描述的其他方面。



我的平台：


  • 经销商编号：Ubuntu描述：Ubuntu 10.10版本：10.10
    代号：maverick jdk1.6.0_26

  • Netbean7.2（Build 201207171143）
  • GlassFish Server 3 +



我的远程接口 

  package ejb.started; 
 // 
 import javax.ejb.Remote; 
 // 
 @Remote 
 public interface StartedSessionBeanRemote {
 
 String getHelloWorld（）; 
 
 $ b $ / code>

其实施：

  package ejb.started; 
 // 
 import javax.ejb.Stateless; 
 // 
 @Stateless（name =StartedSessionBeanRemote）
 public class StartedSessionBean implements StartedSessionBeanRemote {
 $ b @Override 
 public String getHelloWorld（）{
 return（Hello world，EJB！）; 
} 
 
}

客户端代码：

  package startedentappclient; 
 // 
导入ejb.started.StartedSessionBeanRemote; 
 import javax.ejb.EJB; 
 // 
公共类AppClientMain {
 @EJB 
私有静态StartedSessionBeanRemote startedSessionBean; 
 public static void main（String [] args）{
 System.err.println（EJB：+ startedSessionBean.getHelloWorld（））;

当我尝试运行Remote Client proj时，会收到以下输出：
$ b $ pre $ ant -f / home / ilya / Workspace / git / workspace / StartedEntAppClient -DforceRedeploy = false运行

我不能认为是什么问题。我在第二台个人电脑上建立了相同的项目，并成功完成所有工作那个拥有相同的软件平台。

解决方案

我相信你不能使用主方法中的@EJB注释来访问EJB，因为该方法不受服务器管理。相反，您应该使用JNDI。



如何从独立的java客户端访问远程EJB组件？


Good day! I'm newcomer in the JavaEE 6. I tried to create a started project with use of the following tutorial: Creating and Running an Application Client on the GlassFish Server. I created four projects step by step: JavaSE lib to store an EJB Remote Interface, an EJB Module and otherwise as ther're described in the tutorial.

My platform:

  • Distributor ID: Ubuntu Description: Ubuntu 10.10 Release: 10.10 Codename: maverick
  • jdk1.6.0_26
  • Netbean7.2(Build 201207171143)
  • GlassFish Server 3+

My remote interface 

    package ejb.started;
    //    
    import javax.ejb.Remote;
    //
    @Remote
    public interface StartedSessionBeanRemote {

        String getHelloWorld();

    }

Its implementation:

package ejb.started;
//
import javax.ejb.Stateless;
//
@Stateless(name="StartedSessionBeanRemote")
public class StartedSessionBean implements StartedSessionBeanRemote {

    @Override
    public String getHelloWorld() {
       return ("Hello world, EJB!");
    }

}

And the client code:

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());
    }
}

When I try to run the Remote Client proj, I receive the following output:

ant -f /home/ilya/Workspace/git/workspace/StartedEntAppClient -DforceRedeploy=false run

I can't assume what's that problem. I built same projects on my second PC and all work successfully. That one has the same software platform.

解决方案

I believe you cannot access an EJB using the @EJB annotation from a main method because that method is not managed by the server. Instead, you should use JNDI.

How do I access a Remote EJB component from a stand-alone java client?
