-----------------------------------------
Sorry a typo:
So my improvement is to implement an else case which is identical to the else
case of 'if (configLocation == null) {'.
> WAS8: externalize log4j2.xml via URL resource
> ---------------------------------------------
>
> Key: LOG4J2-1045
> URL: https://issues.apache.org/jira/browse/LOG4J2-1045
> Project: Log4j 2
> Issue Type: Improvement
> Components: Configurators
> Affects Versions: 2.3
> Environment: WebSphere 8.0; Win7 x64
> Reporter: Günter Albrecht
> Labels: patch
>
> 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 (config != null) {'.
> With this solution I do not have to implement cumbersome versions for Web-
> and EJB-applications.
