java - Soap WebService 到 Soap Webservice 调用

Question

我在 Netbeans 中创建了两个 Java SOAP Web 服务。基本上每个服务都是一个不同的 Web 应用程序，有自己的 war 文件。我从 Java 客户端调用第一个 WS，并从第一个服务调用第二个服务。当我使用 3 台机器在 LAN 中运行时，它们工作得非常好。客户端、服务 1 和服务 2 位于 3 台独立的计算机上。现在我已经在 J​​elastic Cloud 上部署了服务。第一个服务从客户端调用。但是当第一个服务尝试调用第二个服务时，我收到以下错误。我将 wsdl url 复制粘贴到浏览器中。 WSDL 可用且可访问。所以我确信这不是服务器未部署或 URL 错误的问题。

请帮忙。

Failed to access the WSDL at: http://multipurpose.jelastic.servint.net/ProxyServer/ProxyServerService?wsdl. It failed with:

玻璃鱼 Jelastic正在监听 8080 端口，所有对 80 端口的请求都会通过 iptables 规则重定向到 8080 。您的请求将通过本地接口(interface)进行，环回接口(interface)不使用 PREROUTING 规则。我们已经为您的案例添加了 OUTPUT 规则，并且目前一切正常。此外，我们还进行了一项改进，默认添加 OUTPUT 规则。作为解决方案，您可以在来自本地 GF 节点的请求中指定 8080 端口: http://multipurpose.jelastic.servint.net:8080/ProxyServer/ProxyServerService?wsdl 。
