Thanks for the response, Sorry for the trouble, it seems the email is not
displaying the source code properly when copying the formatted code from
eclipse: trying this again, after copying it from notepad, I only saw this
mailing list that I send an email to, Is there a way that I can post the
response online.
private static void load(String dataFilePath)
throws Exception
{
URL dataFileURL = null;
HierarchicalConfiguration dataFromFile = null;
final File dataFile = new File(dataFilePath);
assertTrue(dataFile.exists(), "Data file does not exist: " + dataFile);
log.info("Reading the data file: " + dataFile);
dataFileURL = ConfigurationUtils.locate(dataFilePath);
log.info(dataFileURL.toString());
dataFromFile = new XMLConfiguration(dataFile);
}
Here is the url that is printed:
2010-05-12 13:23:11,266 INFO c.v.v.e.TestExecutionUtils [load:382] [main] -
file:/G:/testware/events.verification.xml
Yes I tried it with a file, I think I am getting the same error with the same
root cause with the stack trace as below even when I construct the
XMLConfiguration passing a File object.

I still cannot read the source code, but anyway:
Because the exception happens in URLDecoder the URL returned by
ConfigurationUtils seems to be strange. Can you print it out to check
how it actually looks like?
I am not sure why you do the file to URL conversion at all. You can
directly create the XMLConfiguration passing your File object to the
constructor. Did you test this?
