Subject [jira] Commented: (CONFIGURATION-297) NoSuchMethodError if reloading strategy is specified in configuration XML
Date Wed, 03 Oct 2007 15:40:50 GMT


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).

> <?xml version="1.0" encoding="ISO-8859-1" ?>
> <!-- This is the configuration file for the Apache Commons Configuration. -->
> <configuration>
>   	<override>
>     		<properties fileName="" throwExceptionOnMissing="true" config-name="uup"

>   	</override>

> 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!
