通过远程Java独立应用程序使用EJB 3.1 bean [英] using an EJB 3.1 bean through a remote java stand-alone application

问题描述

我一直在尝试使用Java EE 6创建一个基于Application Server的应用程序，该应用程序将从GWT Web应用程序接收Job对象，而这些Jobs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进行远程处理的简便方法，因为我的客户端应用程序应该能够在另一台机器上运行.

I have been trying to use Java EE 6 to create an Application Server based app which is to receive Job objects from a GWT Web Application and those Jobs would be pulled from a Java stand-alone application. I have been thinking that the EJB model would provide me with easy way to do remoting because my client app should be able to run on a different machine.

我将Glassfish 3.1和Netbeans 7.0.1用作我的IDE，我还使用了eclipse Java EE来重现相同的问题.

I am using Glassfish 3.1 and Netbeans 7.0.1 as my IDE, I have also used eclipse Java EE to reproduce same problem.

我一直面临着下一个困难:

I have been facing the next difficulties:

• 要找到InitialContext并不容易，这是使用远程处理的唯一方法吗?
我是否应该能够使用@EJB/@Inject从我的独立应用程序中使用一些配置文件进行一些自动代码注入?
• 我发现了一些要使InitialContext机制起作用的方式(在文档中未直接找到)，我需要添加到我的库中:gf-client-module.jar和weld-osgi-bundle.jar
• 我一直收到下一个错误:

• It was not easy to find out about InitialContext, is it the only way to use the remoting? shouldn't I be able to use @EJB/@Inject for some automatic code injection from my stand alone app using some configuration file?
• I have discovered some how (not found directly in documentation) that for the InitialContext mechanism to work I need to add to my Libraries: gf-client-module.jar and weld-osgi-bundle.jar
• I have been receiving the next error:

在我的场景中，我一直面临着远程使用Java EE 6的问题，但是对于这些问题几乎找不到帮助，将不胜感激.

I have been facing problems with using Java EE 6 remotely in my scenario and have found little help for those problems any assistance would be greatly appreciated.

推荐答案

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

In my case i have the same stack message "Underflow in BufferManagerReadStream after last fragment in message vmcid: OMG minor code: 7"

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

In my project i had a nested object which not implements the Serializable interface. Implementing the Inteface solved my problem.
