Subject [jira] Created: (CONFIGURATION-297) NoSuchMethodError if reloading strategy is specified in configuration XML

NoSuchMethodError if reloading strategy is specified in configuration XML
-------------------------------------------------------------------------

                 Key: CONFIGURATION-297
                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-297
             Project: Commons Configuration
          Issue Type: Bug
    Affects Versions: 1.4
         Environment: Windows XP, WebLogic Portal Server 10.0
            Reporter: Jin Voon


I'm using the DefaultConfigurationBuilder to load the config.xml which contains the configuration
definitions.

DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder();
builder.setFile(new File("config.xml"));
CombinedConfiguration cc = builder.getConfiguration(true);

It definitely finds the config.xml file, but it keeps throwing java.lang.NoSuchMethodError:
getClass during the loading.

lper.java:176)

The config.xml file is:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!-- This is the configuration file for the Apache Commons Configuration. -->
<configuration>
  	<override>
    		<properties fileName="uup.properties" throwExceptionOnMissing="true" config-name="uup"
config-optional="true">
			<reloadingStrategy refreshDelay="10000" config-class="org.apache.commons.configuration.reloading.FileChangedReloadingStrategy"/>
    		</properties>
  	</override>
</configuration>

If I remove the reloadingStrategy element from the config.xml file, everything works properly.
 I can confirm I have all the required commons jars in my classpath.  Would anyone know what
the problem is?  Is there something wrong with my configuration file or is there something
more major?  Thanks!
