>          Issue Type: Bug
>          Components: Configurators

> We're working with WebSphere 8.0 and our operations team has demanded to externalize the {{log4j2.xml}} file per application.
> So I defined a URL resource on WAS8 containing the path to the {{log4j2.xml}} somewhere on the filesystem.
> At first glance the solution seems very simple:
> I defined the property {{log4j.configurationFactory}} in the {{log4j2.component.properties}} file {{log4j.configurationFactory=de.company.MyConfigurationFactory}} available via classpath of the application.
> In this class I specialized the method {{public Configuration getConfiguration(String name, URI configLocation, ClassLoader loader)}}. There I make a lookup to the URL resource.
> But it does'nt function as of a missing implementation in the class {{ConfigurationFactory$Factory}} and the method {{public Configuration getConfiguration(final String name, final URI configLocation)}}. When one enters the method the variable {{configLocation}} is {{null}}. Then the property {{log4j.configurationFile}} is checked which is intentionally not set in the {{log4j2.component.properties}} file as it must be dynamical - via a URL resource.
> Hence also the variable {{config}} is {{null}}. *Unfortunately merely {{config != null}} is handled and no else case is implemented.*
> So my improvement is to implement an else case which is identical to the else case of {{if (configLocation == null)}}.
> With this solution I do not have to implement cumbersome versions for Web- and EJB-applications.
