Thx dubwai
How is file:// prefix on URL used ? Am not sure what
U mean?The String version of the parse method is expecting a URL. What you are passing it is not a valid URL. You need to define the protocol. For example, a URL you use in your browser is http, you need to use file: because the document resides on a file system. You can use file in your browser.
I think you'll fnd it easier to just use the parse(File) method.
