Thanks for the response, Here is the code again, hope this time it does not
appear garbled.
{
URL dataFileURL =
HierarchicalConfiguration dataFromFile =
assertTrue(dataFile.exists(), privatestatic void load(String
dataFilePath)throwsExceptionnull;null;finalFile dataFile =
newFile(dataFilePath);"Data file does not exist: "+ dataFile);dataFileURL =
ConfigurationUtils.locate(dataFilePath);
//The line below throws the error.
dataFromFile =
}
Thankslog.info("Reading the data file: "+
dataFile);newXMLConfiguration(dataFileURL);

Your code example got somehow messed up and is hardly readable. Can you
please repost?
