爲什麼我的Java/SalesForce應用程序由於安全限制而無法創建JAXBContext？

2011-01-22 24 views

我在一個Java/Salesforce tutorial，但我無法讓它工作，因爲SoapBindingStub似乎是基於折舊庫的過時代碼。所以我嘗試使用JAX-WS Quick Start的代碼對代碼進行網格劃分，但是這也沒有起作用。無論我做了什麼，示例控制檯應用程序最終都會遭遇異常，抱怨「Web服務異常創建salesface端口：由於類javax.xml.ws.WebServiceException的安全性限制，無法創建JAXBContext」。我放棄了（暫時）試圖混淆這兩個代碼，而是現在只是在抽象JAX-WS Quickstart.java，以便我能理解它的工作原理，並在其他應用程序中重用其方法。爲什麼我的Java/SalesForce應用程序由於安全限制而無法創建JAXBContext？

無論我如何切片和切塊代碼，它總是被卡在相同的位置，基本上有相同的錯誤。

這裏是方法的當前代碼其persistantly失敗：

private void initPort() 
{ 
    try 
    { 
     URL wsdlLocation = this.getClass().getClassLoader().getResource("META-INF/enterprise.wsdl"); 
     if (wsdlLocation == null) 
     { 
      WebServiceException webServiceException = new WebServiceException("enterprise.wsdl not found!"); 
      ExceptionToolkit.display("Web Service Exception can't find enterprise.wsdl", webServiceException); 
      throw webServiceException; 
     } 
     else {System.out.println("\nFOUND enterprise.wsdl!!!\n\n");} 

     QName qName = new QName("urn:enterprise.soap.sforce.com", "SforceService"); 
     SforceService sforceService = new SforceService(wsdlLocation, qName); 
     System.out.println("\nsforceService INITIALIZED. About to get Soap.\n\n"); 
     Soap soap = (sforceService).getSoap(); 
     System.out.println("\nWe have soap.\n\n"); 
     setPort (soap); 
    } 
    catch (WebServiceException webServiceException) 
    { 
     ExceptionToolkit.display("Web Service Exception creating salesface port", webServiceException); 
     return; 
    } 
}

以下是錯誤，立即之前和之後，包括輸出：在

Running main loop 



FOUND enterprise.wsdl!!! 



sforceService INITIALIZED. About to get Soap.

最後一行（按時間順序）這是指我自己的代碼是：

at hu.flux.salesforce.LoginToolkit.initPort(LoginToolkit.java:78)

System.out.println stat源代碼中的元素確認這是執行終止的內容。該行特別指出：

Soap soap = (sforceService).getSoap();

有誰知道如何或爲何這可能超越安全限制最終放棄Java無法創建的JAXBContext？

看起來您正在嘗試製作一個Web服務，該服務的合同中包含java.lang.Exception或StackTraceElement的子類。你不能那樣做。處理異常的唯一方法是使用錯誤。

您是否在salesforce之外完成了所有這些工作？

請注意，您的代碼不便於手動初始化JAXB上下文，但是您沒有將它傳遞到JAX-WS調用中，因此堆棧正在創建新的JAXB上下文並嘗試進入問題。你記得它傳遞到綁定提供者，如...

try { 
     jc = JAXBContext.newInstance("com.salesforce.sei"); 
     bindingProvider.setOutboundHeaders(Headers.create((JAXBRIContext) jc, sh)); 
    } catch (JAXBException e) { 
     System.out.println("Error creating JAXBContext instance " + e.getMessage()); 
     return false; 
    }

我在這段代碼中沒有使用任何子類。我正在研究的教程都是關於使用Java與SalesForce，所以我不知道如何才能明智地將銷售人員排除在外。 – 2011-01-23 00:45:47

順便說一句，我認爲異常處理得很好，我只是不清楚爲什麼我得到這個特定的時候，因爲似乎有訪問WSDL或創建SOAP對象的某種限制。 – 2011-01-23 00:53:34
