FacesServlet在Google上使用FacesServlet时拒绝访问

Question

我正在用Google在Java上开发一个使用Web服务的示例应用程序。当我在本地环境中工作，服务器服务部署在我的google帐户中，客户端部署在我的本地环境中时，一切都很好。

当我在Google上部署应用程序并尝试执行它时，问题就出现了。当后台bean试图创建服务器客户端的实例时，会发生异常：

这是我得到的例外：

异常的跟踪从以下代码行开始：

AutomovilServletClient clienteService = new AutomovilServletClient();

AutomovilServletClient有一个构造函数来初始化API服务：

public AutomovilServletClient() {
      this.automovilAPI = new AutomovilServerAPIService().getAutomovilServerAPIPort();
  }

首先是AutomovilServerAPIService的构造函数：

@WebServiceClient(name = "AutomovilServerAPIService", targetNamespace = "http://server.beeva.com/", wsdlLocation = "http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl")
public class AutomovilServerAPIService
    extends Service
{

    private final static URL AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION;
    private final static Logger logger = Logger.getLogger(com.beeva.client.gen.AutomovilServerAPIService.class.getName());

    static {
        URL url = null;
        try {
            URL baseUrl;
            baseUrl = com.beeva.client.gen.AutomovilServerAPIService.class.getResource(".");
            url = new URL(baseUrl, "http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl");
        } catch (MalformedURLException e) {
            logger.warning("Failed to create URL for the wsdl Location: 'http://1.XXXX.appspot.com/AutomovilServerAPIService.wsdl', retrying as a local file");
            logger.warning(e.getMessage());
        }
        AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION = url;
    }

public AutomovilServerAPIService() {
        super(AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION, new QName("http://server.beeva.com/", "AutomovilServerAPIService"));
    }

}

在方法中，AutomovilServerAPIService()是我无法跟踪执行的地方。我检查了常量AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION的内容，它是正确的。

有人知道当它被部署到时为什么会发生这种情况吗？

提前感谢

更新:尝试 Google开发人员的SOAP示例 ，我发现使用带来了问题。我的项目是一个具有JSF功能的Google应用程序项目。因此，web.xml中的这一行是导致问题的原因：

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
    <url-pattern>*.jsf</url-pattern>
  </servlet-mapping>

然而，不知道如何修复它:(

更新2:解决了！！我发现问题在于GAE与ApacheJSF-Core2.0不兼容。当通过属性/项目面添加JSF功能时，选择JSF2.0(mojarra2.Z.X-FCS)而不是Apache MyFaces

Answer 1

我在https://developers.google.com/appengine/articles/soap上试了一个例子，它在本地和网上都能使用。

我在在线部署之前所做的更改如下：

• 对于服务器应用程序，在wsdl文件中更改了url
• 对于客户端应用程序，请在SOAPService.java中更改url

我想你已经做了第二次改变了。

您能否确认在联机部署之前是否已更新了WSDL文件？

<service name="TestSOAPService">
  <port name="TestSOAPPort" binding="tns:TestSOAPPortBinding">
     <soap:address location="**http://CHANGE_TO_ONLINEID.appspot.com**/testsoap"/>
  </port>
</service>
