Trying to follow your tips but now I have this class cast exception,
my factory looks like this :
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<additional>
<xml fileName="ress/ApplicationConfig.xml"/>
</additional>
</configuration>

ConfigurationFactory takes all configurations defined in an <additional>
section and combines them to a single HierarchicalConfiguration. This is
the reason for your ClassCastException. If you remove the <additional>
tags and define the XMLConfiguration in the top level, you should be
able to access it in the described way.
Alternatively you can give the DefaultConfigurationBuilder (introduced
with Configuration 1.3) a try. This class provides a slightly richer
API. It is fully described in the user guide.

Hi,
I am using this snippet of code to get dynamically the configuration
settings of my app. :
URL url =
Thread.currentThread().getContextClassLoader().getResource(
"ress/config.xml");
ConfigurationFactory factory =* **new* ConfigurationFactory();
factory.setConfigurationURL(url);
Configuration conf =* null*;
*try* {
conf = factory.getConfiguration();
}* catch* (ConfigurationException e) {
e.printStackTrace();
}
The problem here is that I am trying to get an XMLConfiguration and
not
a Configuraton object,
to do operations on the configuration file itself (change the
settings),
which is an XML file.
any tips on how to get an XMLConfiguration from a the
ConfigurationFactory ?
Thank u !

You can cast the Configuration object you obtain from the factory to a
CompositeConfiguration. This class provides the getConfiguration(int
index) method, which gives you access to the child configurations. The
XMLConfiguration you have loaded using the factory will be one of those.
