weblogic 中的 java.io.EOFException

Question

您好，我很难尝试为无状态 bean (Spring) 配置 weblogic。我是那个领域的新手。

我有 2 层应用程序。服务器(weblogic + DB + java app)和用swing写的客户端。调用此行时:

getCtx().lookup(SomeStatelessRemoteHome.class.getName()), SomeStatelessRemoteHome.class);

我遇到了这个错误:

Caused by: javax.naming.CommunicationException [Root exception is weblogic.rjvm.PeerGoneException: ; nested exception is:

EJB 自动部署在服务器上。我已经使用调试属性运行 weblogic，但 weblogic 服务器上的日志中没有任何内容。仅在客户端显示此堆栈跟踪。

发生此异常后，weblogic 将失去与客户端的所有连接。

我在 weblogic 上的 config.xml 是:

我对它进行了一些审查 :)。

如果能提供一些帮助，我将不胜感激。

已修复:

我在 Weblogic 上添加了调试选项:

-Dweblogic.kernel.debug=true 
-Dweblogic.debug.DebugConnection=true 
-Dweblogic.StdoutDebugEnabled=true 
-Dweblogic.log.LogSeverity=Debug 
-Dweblogic.log.LoggerSeverity=Debug

其中一个 jar 文件的路径有误。所以它抛出了“ClassNotFoundException”。调试让我找到了它……简单的错误是最烦人的；)。
