独特的困惑JBOSS RESTEASY错误 - 找不到资源

Question

通过负载平衡的Web服务器访问REST URL（2个Web服务器将请求转发到两个应用程序服务器）遇到了问题。当设置为单个Web服务器到单个JBOSS应用服务器时，不会发生此问题。

以下是我从JBOSS应用程序服务器日志中看到的错误消息：

16:02:46,711 DEBUG [org.jboss.resteasy.core.SynchronousDispatcher] (http-/30.31.32.33:8080-14) PathInfo: //AppName/rest/game/userStatus

        GameService gs = new GameService();
        return gs.getUserReportStatus(userId);

}

以下是Web.xml的主要内容：

我期望的结果是：

{"status":"Yes","dob":"01/01/1934","userName":"John Doe","reportStatus":"No"}

我在提出应用程序服务器的IP地址时会收到上述正确的结果http://30.31.32.33:8080/appname/rest/game/game/userstatus?userid=99984029883634

通过负载平衡的Web服务器，我获得的实际结果是：

HTTP Status 404 - Could not find resource for relative : //AppName/rest/game/userStatus of full path: http://stg.testing.com//AppName/rest/game/userStatus?userId=99984029883634

在向Web服务器URL请求时，我会收到上述结果。http://stg.testing.com/appname/rest/game/userstatus?userid=99984029883634

注意：我通过将stg.testing.com分配给Web服务器IP进行了测试 主机文件中的地址。

以下是httpd.conf文件W.R.T中的设置。

我将JBOSS 7.1.2用作我的应用服务器，而Apache作为Web服务器。此REST应用程序在后端使用Axis SOAP WebService客户端。因此，我在web.xml中具有与轴相关的语句。我已经证实了肥皂客户在两种情况下都可以使用。我不确定这是否是由于Web服务器问题（在AppName之前自动添加2个前向斜线）或类似于此处列出的JBOSS问题， 这里 和这里我已经尝试了以上有关JBOSS修复的三个建议，但仍然存在相同的错误。识别我错误原因的任何帮助都很棒。

一个更新：我通过将servlet插入上下文root下的单独目录中，并且可以从负载平衡器中触及servlet。因此，就目前而言，我假设这是一个软件问题，而不是硬件问题。另外，作为org.jboss.resteasy.core.core.synchronousdispatcher在请求期间被调用，我假设它不是404，而是一个内部重定向，该重定向引起双向斜线。任何帮助都是有用的。预先感谢。

今天我们找到了这个问题。该问题是由httpd.conf

中的Balancermember URL语句中的额外"/"引起的。

现在，Balancermember URL语句已更改为

.

<Proxy balancer://stgsilo stickysession=JSESSIONID>
   BalancerMember http://30.31.32.33:8080 min=10 max=100 route=node1 loadfactor=1
   BalancerMember http://30.31.32.34:8080 min=10 max=100 route=node2 loadfactor=1
</proxy>
