Try using ConfigurationBuilder instead of ConfigurationFactory, you

I get it with the following:
try {
DefaultConfigurationBuilder builder = new
DefaultConfigurationBuilder();
builder.setURL(configURL);
this.clear();
this.addConfiguration((AbstractConfiguration)builder.getConfiguration());
}
when reading:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
<properties fileName="config.properties" />
<properties fileName="deploy.properties" optional="true" />
<xml fileName="config.xml" />
</configuration>
and "deploy.properties" is not available to be read. I just assumed
this was a warning I had to put up with.
DEBUG ation.ConfigurationUtils : ConfigurationUtils.locate(): base is
file:[...]/build/MiniSandbox.woa/Contents/Resources/,
name is deploy.properties
WARN aultConfigurationBuilder : Internal error
org.apache.commons.configuration.ConfigurationException:

org.apache.commons.configuration.AbstractFileConfiguration. \
load(AbstractFileConfiguration.java:215)
I stepped my way through the code in question and don't understand
what's happening.
The isOptional() method's return value is true at line 975 of
DefaultConfigurationBuilder,
so it ought to not throw the exception -- but it does.
catch (Exception ex)
{
// If this is an optional configuration, ignore the exception
if (!decl.isOptional())
{
throw ex;
}
else
{
All the source I explored is from the sources.jar that is a part of
config 1.5
If a configuration marked as optional cannot be loaded,
DefaultConfigurationBuilder notifies all registered error listeners
(i.e. an error event is fired). Per default, an error listener is
registered that only logs the causing exception.
To disable this behavior you can call clearErrorListeners() on the
DefaultConfigurationBuilder instance.
