SAXParseException與AXIS Webservice Framework

我們正在開發Web服務解決方案。 webservice API爲我們提供了幾個調用，我們可以使用它們從客戶端WebService實現中檢索SOAP響應。SAXParseException與AXIS Webservice Framework

該實現基於AXIS框架。

所有的API調用都能很好地工作，除非我們在返回響應時遇到SAXParseException。

當我們在SOAP UI中嘗試時，我們得到了針對這個特定API的有效響應。但是當我們在Java項目中嘗試時，我們得到了這個SAXParseException。 Java和SOAP用戶界面項目都是使用相同的WSDL文件創建的

請查看下面的堆棧跟蹤並分享您的卑微觀點，看看這裏可能出現了什麼問題。

看來你沒有得到有效的XML響應......類似的東西。

<?xml version="1.0"?> 
<node1> 
... bla, bla 
</node1> 
<node2> 
... bla, bla 
</node2> 
<node_x> 
... bla, bla 
</node_x>

，而不是...

<?xml version="1.0"?> 
<node1> 
    <node2> 
    ... bla, bla 
    </node2> 
    <node_x> 
    ... bla, bla 
    </node_x> 
</node1>

你應該嗅探網絡流量以原始格式的內容。如果有人用手工構造xml代碼而不用熟知的工具，我通常會得到這個錯誤。

是的，即使我這麼認爲。我們仍然有同樣的錯誤。當我們在SOAP用戶界面中嘗試時，我們得到了對這個特定API有效的響應但是當我們嘗試使用Java時，我們會遇到這個錯誤。 Java和SOAP UI項目都是使用相同的WSDL文件創建的 – tiger 2013-05-15 09:02:32
