Thanks for the response, Here is the code again, hope this time it does not
appear garbled.

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?

Hi,
I have been running into an issue while creating an xml configuration object
from an xml file, I am using jdk 1.6.0_20 and commons-configuration-1.6.jar,
similar code works when the method is non-static, appreciate any comments or
pointers in resolving this issue
Here is the code which is creating this XMLConfiguration object.
privatestatic void load(String dataFilePath)throwsExceptionnull;null; finalFile dataFile =
newFile(dataFilePath);"Data file does not exist: "+ dataFile);// this check succeeds no assertion
error is thrown"Data file is not readable: "+ dataFile);// this check succeeds no assertion error
is thrown log.info("Reading the data file: "+ dataFile);newXMLConfiguration(dataFileURL);
{
URL dataFileURL =
HierarchicalConfiguration dataFromFile =
assertTrue(dataFile.exists(),
assertTrue(dataFile.canRead(),
dataFileURL = ConfigurationUtils.locate(dataFilePath); //Returns a proper
url of the file passed.
dataFromFile =
}
Your code example got somehow messed up and is hardly readable. Can you
please repost?
