hi
I've tried this code to validate XML using xsd file:

 
public static void validate(String xmlFilePath, URL schemaFileUrl)
	{
		try
		{
			SAXParserFactory factory = SAXParserFactory.newInstance();
			factory.setValidating(false);// stop standard validation to allow
											// custom schema
			factory.setNamespaceAware(true);

			SchemaFactory schemaFactory = SchemaFactory
					.newInstance(javax.xml.XMLConstants.W3C_XML_SCHEMA_NS_URI);

			factory.setSchema(schemaFactory.newSchema(schemaFileUrl));
			SAXParser parser = factory.newSAXParser();

			XMLReader reader = parser.getXMLReader();

			// Register the error handler
			reader.setErrorHandler(new JS_ValidationError());
			// Parse the file as the first argument on the command-line
			reader.parse(xmlFilePath);
		} 
		catch (SAXException e)
		{
			System.out.println("Error: " + e.getMessage());
			e.printStackTrace();
		} catch (IOException e)
		{
			System.out.println("Error: " + e.getMessage());
			e.printStackTrace();
		} catch (ParserConfigurationException e)
		{
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

I have called this method ,but it issues this error :"unknown protocol" followed by windows partition name, in the debug I found that the value of the url is "file://(windows-partiton-char)/rest of path" !!!
this should work but it doesn't!!

so how can I fix this problem?

thanks

just as a suggestion and you might have already thought of this, but try creating a file input stream to pass to the reader.parse() method in stead of passing the file path as a string.

Another suggestion. I use JAXB for my metadata entry applications, it works very well, but it might be over kill for what you're trying to do. https://jaxb.dev.java.net/

hi
some friend sent me this code , and it works by using FileInputStream, I hope this Schema class can be fixed in next java releases!!

thanks pjupson for your concern and help.
