Oliver Heger commented on CONFIGURATION-297:
--------------------------------------------
This does not appear to be a specific problem of Commons Configuration, but a
class path issue (welcome to jar hell ;-)
>From tracking down the stack trace, the exception is thrown at a point where
>org.apache.commons.lang.ClassUtils.getClass(String) is invoked. This class is
>part of Commons Lang. It seems that you have an older version of this library
>in your class path, in which the ClassUtils class does not have this method.
>Maybe a version of Commons Lang is already bundled with WebLogic Portal Server?
Try to pack the newest version of Commons Lang to your web application (i.e. in
WEB-INF/lib).

> 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.

> 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!
