FacesServlet在Google App Engine上使用Web服務時拒絕訪問

2013-05-30 105 views

我正在使用Google App Engine開發一個使用Web服務的Java示例應用程序。 當我在本地環境中工作時，一切正常，服務器服務部署在我的Google帳戶中，並且客戶端部署在本地環境中。FacesServlet在Google App Engine上使用Web服務時拒絕訪問

當我在Google App Engine上部署應用程序並嘗試執行它時，問題就出現了。當支持bean試圖創建服務器客戶端的一個實例發生異常：

這是例外，我得到：

異常的痕跡在這行代碼開始：

AutomovilServletClient clienteService = new AutomovilServletClient();

AutomovilServletClient具有初始化API服務構造：

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

首先去AutomovilServerAPIService的構造函數：

@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AutomovilServerAPIService（）是我失去跟蹤的執行。我檢查了常量AUTOMOVILSERVERAPISERVICE_WSDL_LOCATION的內容，它是正確的。

任何人都知道爲什麼它會在部署到Google App Engine時發生？

在此先感謝

UPDATE：嘗試SOAP example of Google Developers我發現，問題就來與使用Java服務器的Servlet的面孔。我的項目是一個具有JSF功能的Google Web應用程序項目。因此，這條線在web.xml是什麼原因造成的問題：

<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>

但是，我不知道如何解決它:(

更新2： 解決!!我有發現這個問題與Apache MyFaces JSF-Core 2.0不兼容。當通過properties/Project Facets添加JSF Capabilities時，選擇JSF 2.0（Mojarra 2.ZX-FCS）而不是Apache MyFaces

我試過了在https://developers.google.com/appengine/articles/soap，它在本地和在線上都可以工作。

我在網上部署之前所作的改動：在SOAPService.java

  • 服務器應用在WSDL文件
  • 改網址，客戶端應用程序更改URL

我想你第二個變化已經完成了。

您可以確認在部署在線之前是否更新了WSDL文件？

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

是的，服務器和客戶端都具有相同的WSDL文件位置值。但是，我沒有嘗試谷歌開發人員的例子。我會建立它，看看有沒有不同。感謝那 ：） –
