the third / is in the wrong place, the file url is contructed with file:///<path>

Adding an extra slash in front of the path fixed the problem. Apparently, file:///D/:/dev/test_all.html is considered legal.

As mentioned in www.coderanch.com/t/185526/java-developer-SCJD/certification/UnknownHostException. The format is protocol://hostname/file and since the host name is empty you end up with three slashes (protocol:///file).

Simply placing the current directory file name didn't resolve correctly. Is that platform based Java bug?

Path are resolved based on the directory where your application did start from. So it depends a bit where you started the application and what file indication you used. But that is worth a seperate question
Your URL is malformed. Instead of file://D/:/ you want file://D:/ -- no slash between the drive letter and the colon.

Here is my solution that's actually working with XMLParserv2, I hope this helps:
protected URL createURL(String filename){
URL url = null;
try {
url = new URL("file://" + System.getProperty("user.dir") + File.separator + filename);
} catch (MalformedURLException e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
return url;
}
