Question

在一项功能中，我构建了一个逻辑，用于使用JCIFS的SmbFile概念从上传的xml文件中读取值，该文件位于远程保护共享文件夹中，如下所示：

String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";    
String strStImgPath = PROTECTED_SHARE_FOLDER_PATH;
String strFileName = "SampleFile.xml";
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(DOMAIN, USER,    
PASSWORD);
SmbFile fNew = new SmbFile(strStImgPath, strFileName, auth);
SmbFileOutputStream fout = new SmbFileOutputStream(fNew, false);
fout.write(foFile.getFileData());
fout.close();

Document doc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
try {
   factory.setAttribute(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
   factory.setAttribute(JAXP_SCHEMA_SOURCE, new SmbFile(schemaSource, auth));
} catch (IllegalArgumentException x) {
   x.printStackTrace();
}

try {
   DocumentBuilder builder = factory.newDocumentBuilder();
   DefaultErrorHandler parserErrors = new DefaultErrorHandler();
   builder.setErrorHandler(parserErrors);
   **doc = builder.parse(new SmbFileInputStream(fNew));**
} catch (Exception e) {
   e.printStackTrace();
}

行doc = builder.parse(new SmbFileInputStream(fNew));抛出以下异常：

org.xml.sax.SAXException: "http://java.sun.com/xml/jaxp/properties/schemaSource" property cannot have a value of type {jcifs.smb.SmbFile}. Possible types of the value supported are String, File, InputStream, InputSource OR an array of these types.

有谁可以告诉为什么会发生此异常？什么可以替代解决这个问题。

感谢。

嗯，错误信息非常自我解释？

Parser不喜欢你的SmbFile作为模式源（如果你查看SmbFile的文档，例如在http://www.jarvana.com/jarvana/view/org/samba/jcifs/jcifs/1.2.19/jcifs-1.2.19-javadoc.jar!/jcifs/smb/SmbFile.html），你会看到SmbFile不会从解析器接受的任何类中下降

作为一个详细的猜测，我会尝试

factory.setAttribute(JAXP_SCHEMA_SOURCE, new SmbFile(schemaSource, auth).getInputStream());

看看会发生什么......
