在Resin和Spring-WS中加載XML模式文檔的問題

Question

嘗試在Resin 3.0.25容器中加載XML模式文件時，出現以下異常。 除了XML Schema名稱空間（http://www.w3.org/2001/XMLSchema）外，該模式文件沒有引用任何外部內容。 XML模式文件有效，使用Jetty容器時，完全相同的代碼也可以工作。

運行Resin的計算機無法訪問Internet，運行Jetty的計算機可以訪問互聯網。

我已經嘗試過像這樣的不同XML解析器，但是它似乎沒有任何作用。

-Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl 
-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl

這種行為可能是什么原因？

編輯：與彈簧配置略有不同，我正在此堆棧跟蹤

Answer 1

可能沒有互聯網連接，就無法下載XSD的架構。 您可能可以嘗試使用XML Catalog指向本地可用的架構。

Answer 2

我不知道為什么會發生此錯誤，但是有效的解決方案是升級到Resin 3.1.10。
