Question

我尝试将各种帖子和教程中的[相关部分]相关部分组合起来创建Eclipse项目，我可以使用Glassfish的appclient调用无状态bean上的方法部署到Glassfish。当我运行appclient时，我似乎无法通过“未找到类”错误。

为了提高效率，我希望能够在组装具体步骤方面获得一些帮助，以便其他人也可以从这项练习中受益 - 我一直在寻找几天来寻找一套对于这样的事情的具体步骤，并没有发现任何小，简洁和完整。为了给予适当的确认，大部分内容都是根据http://programming.manessinger.com/tutorials/an-eclipse-glassfish-java-ee-6-tutorial/

改编的

环境是：
- Eclipse Juno，SR2
- Glassfish 3.1.2
- JDK 1.7.0.21

(Apologies for the formatting; I couldn't get indentation to work the way I wanted)  

These are the steps I've followed (which don't work, and where I'm asking for help):  
1. Create an Eclipse EAR Project:  
  1a. New Project -> Java EE -> Enterprise Application Project  
  1b. Project name: AdderEAR  
2. Create an Eclipse EJB Project, and add it to EAR Project:  
  2a. New Project -> EJB -> EJB Project  
  2b. Project name: AdderEJB  
  2c. Add project to an EAR: AdderEAR  
    ** After this, there are 3 projects: AdderEAR, AdderEJB, and AdderEJBClient.  
3. EJB Project: Add "adder" package, and adder.adderBean class:  
  3a. AdderEJB -> New Package ("adder")  
  3b. AdderEJB -> adder -> New Session Bean:  
    3b1> Class name: AdderBean  
    3b2> State type: Stateless  
    3b3> No-interface View (selected)  
    3b4> Remote ("adder.AdderBeanRemote")  
    ** AdderEJB: adder.AdderBean.java file created  
    ** AdderEJBClient: adder.AdderBeanRemove.java file created  
4. Add "sum" method to AdderBeanRemove interface and AdderBean EJB  
5. Start glassfish server  
6. Deploy AdderEAR to glassfish:  
  6a. Right-click Glassfish server in Servers view  
  6b. Add and Remove...  
  6c. Select AdderEAR and add  
7. Create Adder appclient Project:  
  7a. New Project -> Java EE -> Application Client Project  
  7b. Project name: AdderAppClient  
  ** AdderAppClient: [default package].Main.java file created  
8. Edit Main.java to include EJB of type AdderBeanRemote as static field:  
9. Use Eclipse "Quick fix" to do the following:  
  9a. On error at @EJB: Fix project setup -> Add archive 'javax.ejb.jar'  
  9b. On error at static field: fix project setup -> Add project 'AdderEJBClient' to build path...  
10. Add a couple println's to main() in Main.java, including invocation of adderBean.sum()  
** No errors detected by Eclipse at this point; all files saved  
11. Export app client jar:  
  11a. AdderAppClient -> Export -> App Client Jar File to ~/tmp/AdderAppClient.jar  
12. Run appclient using acc-sum.xml of same domain where eclipse deployed the EAR:  
  12a. cd ~/tmp  
  12b. appclient -xml ~/personal_domain/config/sun-acc.xml -jar AdderAppClient.jar

这是错误发生的地方：

    $ cd ~/tmp
    $ ls
    AdderAppClient.jar
    $ appclient -xml ~/personal_domain/config/sun-acc.xml -jar AdderAppClient.jar

以下是eclipse的相关文件：

    // Main.java: -------------------------------------------------------

    import javax.ejb.EJB;
    import adder.AdderBeanRemote;

    public class Main
    {
      @EJB
      public static AdderBeanRemote adderBean;

      public static void main(final String[] args)
      {
        System.out.println("In AdderAppClient:main()");
        System.out.println("Sum of 3 and 4 is " + adderBean.sum(3, 4));
      }

      public Main()
      {
        super();
      }
    }

    // AdderBeanRemote.java: ----------------------------------------------

    package adder;

    import javax.ejb.Remote;

    @Remote
    public interface AdderBeanRemote
    {
      public int sum(int a, int b);
    }

    // AdderBean.java:  ---------------------------------------------------

    package adder;

    import javax.ejb.LocalBean;
    import javax.ejb.Stateless;

    @Stateless
    @LocalBean
    public class AdderBean
        implements AdderBeanRemote
    {
      public AdderBean()
      {
      }

      @Override
      public int sum(final int a, final int b)
      {
        return a + b;
      }
    }

这是我第一次尝试在eclipse和glassfish的appclient中使用EJB，所以我怀疑我的错误是非常基本的，而且由于缺乏熟悉性，我错过了一些基本的东西。任何指针都会非常感激。

如何使用glassfish appclient和ejb进行eclipse
