我一直在尝试使用 Java EE 6 创建一个基于应用程序服务器的应用程序，该应用程序将从 GWT Web 应用程序接收作业对象，并且这些作业将从 Java 独立应用程序中提取。我一直认为 EJB 模型将为我提供一种简单的远程处理方法，因为我的客户端应用程序应该能够在不同的机器上运行。

我使用 Glassfish 3.1 和 Netbeans 7.0.1 作为我的 IDE，我也使用 eclipse Java EE 来重现同样的问题。

我一直面临着下一个困难：

  • 不容易发现InitialContext，是不是只能使用remoting？我不应该能够使用@EJB/@Inject使用一些配置文件从我的独立应用程序中进行一些自动代码注入吗？
  • 我发现了一些方法（未直接在文档中找到），InitialContext我需要将机制工作添加到我的库中：gf-client-module.jar和weld-osgi-bundle.jar
  • 我一直收到下一个错误：

我一直面临在我的场景中远程使用 Java EE 6 的问题，并且对这些问题几乎没有帮助，任何帮助将不胜感激。

在我的情况下，我有相同的堆栈消息“在消息 vmcid 中的最后一个片段之后，BufferManagerReadStream 中的下溢：OMG 次要代码：7”

在我的项目中，我有一个未实现 Serializable 接口的嵌套对象。实现接口解决了我的问题。

您是否注意在 rmi 调用方法 getSimpleJobForProcessing 时作为参数传递的对象的类实现了接口 java.io.Serializable？这也是为什么我有这样的例外的原因之一。

The @EJB annotation is processed and interpreted by a Java EE compliant container, so as far as I know there is no simple way to do this from a Java application that doesn't run in a container.

However, if you are running from a Glassfish container, you might be able to get rid of the JNDI lookup.

You can try the following:

@EJB(name = "RemoteService") 
private StatusService remoteService;

and then in your sun-web.xml:

   <ejb-ref> 
            <ejb-ref-name>RemoteService</ejb-ref-name> 
            <jndi-name>java:comp/env/com//RemoteService</jndi-name> 
    </ejb-ref>

With the exception, I cannot help.
