Subject [jira] Commented: (CONFIGURATION-297) NoSuchMethodError if reloading strategy is specified in configuration XML
Date Wed, 03 Oct 2007 03:36:50 GMT

Jin Voon commented on CONFIGURATION-297:
----------------------------------------

Please note I tried this in an application running in WebLogic Portal Server.  When I tried
it on a standalone Java app, this problem does not exists.

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!
