java.net.MalformedURLException: no protocol

Question

I' m writing a class to run xjc in java. my code goes as follows:

 URL url = new URL("C:\\Users\\Simran\\Desktop\\books.xsd"); 
 SchemaCompiler sc = XJC.createSchemaCompiler();
 sc.parseSchema(new InputSource(url.toExternalForm()));
 S2JJAXBModel model = sc.bind();
 JCodeModel cm = model.generateCode(null, null);
 cm.build(new FileCodeWriter(new File("C:\\Users\\Simran\\Desktop\\books.xsd")));

however I get the following error when I run this:

Exception in thread "main" java.net.MalformedURLException: no protocol: books.xsd
    at java.net.URL.<init>(Unknown Source)
    at java.net.URL.<init>(Unknown Source)
    at java.net.URL.<init>(Unknown Source)
    at jaxbTest.Test1.main(Test1.java:22)

Can anyone help with this please?

Have you tried sc.parseSchema(new InputSource("C:\\Users\\Simran\\Desktop\\books.xsd")); As I suggested before ? — Jigar Joshi

Try append "file://" to the beginning of your file path. But as Bozho proposed, you don't need an URL here.

This is not a valid URL. It can be made valid by prepending file:// as protocol.

But you don't need a URL at all. You can pass a Reader (as well as an InputStream) to the InputSource constructor. So for example:

new InputSource(new FileReader(path))

i always thought that it was with three /'s, like file:///, but am upvoting this answer. also the correct term is not appending but prepending.

thanks for the "prepending". It works with two slashes as well, I'm not sure which is the standard. I guess it gets normalized regardless of the number of slashes.
