我的項目有一個JAXWS類，其中讀取了XSD並最終通過另一種方法進行了驗證。嘗試讀取xsd時出現SAXParserException
這裏是Java代碼在那裏讀出的XSD
private static final ThreadLocal <DocumentBuilder> parser =
new ThreadLocal <DocumentBuilder>() {
@Override protected DocumentBuilder initialValue() {
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
// loading Schema file
//System.out.println("Hi .. am in parser");
DocumentBuilder parserBuilder = null;
if(finalXsd !=null){
logger.info("finalXsd FILE"+finalXsd);
Source schemaFile = new StreamSource(new File(finalXsd));
try{
logger.info ("place-0") ;
Schema schema = factory.newSchema(schemaFile);
logger.info ("place-1") ;
docBuilderFactory.setValidating(false); // true is used for DTD based validation, for schema validation set to false
logger.info ("place-2") ;
docBuilderFactory.setSchema(schema);
logger.info ("place-3") ;
parserBuilder = docBuilderFactory.newDocumentBuilder();
logger.info ("place-4") ;
parserBuilder.setErrorHandler(new JythonResponseErrorHandler());
logger.info ("place-5") ;
}catch(SAXException s)
{
logger.error("SAXException in ThreadLocal.");
s.printStackTrace() ;
return null;
} catch (ParserConfigurationException e) {
e.printStackTrace();
logger.error("ParserConfigurationException in ThreadLocal.");
return null;
}
}
return parserBuilder;
}
};
XSD文件（它上面的代碼試圖讀取）：

在發送從SOAP-UI的響應，則上面的代碼得到執行並拋出異常

我甚至試圖將XS更改爲XSD在xs d文件。但我仍然得到這個例外。
請幫我在這
感謝 阿倫
拋出異常究竟在哪裏？ 您是否驗證過（在代碼中）finalXsd準確表示正確的路徑？ 您覈實了XMLConstants.W3C_XML_SCHEMA_NS_URI確實與「http://www.w3.org/2001/XMLSchema」匹配嗎？ （好吧，最後一個是有點延伸 - 它應該這樣做）。 – GregHNZ 2012-03-16 08:23:55
在Schema schema = factory.newSchema（schemaFile）中引發異常。 正好在logger.info（「place-0」）之後; 。路徑是正確的格雷格 – Arun 2012-03-16 08:28:44
