大家好，我正在尝试创建一个 RESTful Web 服务，它将通过 SOAP 从 SAP 应用程序中获取一些数据，然后将这些数据传输到 JSON，然后可以通过 REST 调用访问这些数据。
我正在使用 Jetty 作为我的应用程序服务器，当我尝试访问这个 URL 时，我在运行 Jetty 的终端中得到了这个：
http://localhost:9090/cxf/json/appName/filteredList/someVar=test?nocache=y
我的浏览器只显示“{“MyData”：[]}”
ERROR - SapSoapHelper - Loading wsdl from: file:/Users/me/workspace/projects/myProjects/target/classes/wsdl/myWSDL.wsdl
ERROR - SapSoapHelper - There was a problem calling the web service

我很确定我的注释是正确的，我想知道这是否可能是 Jetty 的问题。有什么建议吗？
这是我的 web.xml 文件的一个片段，我是 REST Web 服务的新手，所以我不确定还有哪些其他信息有助于弄清楚发生了什么。
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/cxf/*</url-pattern>
</servlet-mapping>
任何帮助将不胜感激，谢谢。
FIX：我终于弄清楚为什么会发生这种情况。我在公司防火墙后面工作，并在 ~/.bash_profile 中编辑了我的 $http_proxy 以适应这一点。我必须从 ~/.bash_profile 中删除我的 $http_proxy 设置才能使其正常工作。
