I had an existing class to read/write an xml fle using apache's DOMParser. However after modifying the file to use sun's DOMParser, I see that only the write part works and not the read part. I get a MalformedURLException exception when trying to read the file as follows:
That's right, a file path is not a URL. You could try to make your path into a file URL by prefixing it with "file://", although I'm never sure whether you need two or three slashes. Or you could see if the parse() method has an overloaded version that takes, for example, a File object.
