Configuration of log4j

[macoute]

Hi at all,

I've a problem to configure log4j in my J2EE application.

I have a log4j.xml in my classpath, as follow:

?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'>








<level="DEBUG"/>
<appender-ref ref="PDM_STDOUT"/>


</log4j:configuration>

And I'm using the following class to set my logging context.

public class PDMRepositorySelector implements RepositorySelector {
private static boolean initialized = false;
private static Object guard = LogManager.getRootLogger();

private static Map repositories = new HashMap();
private static LoggerRepository defaultRepository;

/**
* Register your web-app with this repository selector.
*/
public static synchronized void init() throws ServletException {
if( !initialized ) // set the global RepositorySelector
{
defaultRepository = LogManager.getLoggerRepository();
RepositorySelector theSelector = new PDMRepositorySelector();
LogManager.setRepositorySelector(theSelector, guard);
initialized = true;
}

Hierarchy hierarchy = new Hierarchy(new RootCategory(Level.DEBUG));
loadLog4JConfig(hierarchy);
ClassLoader loader = Thread.currentThread().getContextClassLoader();
repositories.put(loader, hierarchy);


}

public static synchronized void removeFromRepository() {
repositories.remove(Thread.currentThread().getContextClassLoader());
}

private static void loadLog4JConfig(Hierarchy hierarchy) throws ServletException {
try {
String log4jFile = "log4j.xml";
InputStream log4JConfig = Thread.currentThread().getContextClassLoader().getResourceAsStream(log4jFile);
Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(log4JConfig);
DOMConfigurator conf = new DOMConfigurator();
conf.doConfigure(doc.getDocumentElement(), hierarchy);
} catch (Exception e) {
throw new ServletException(e);
}
}

private PDMRepositorySelector() {
}

public LoggerRepository getLoggerRepository() {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
LoggerRepository repository = (LoggerRepository)repositories.get(loader);

if (repository == null) {
return defaultRepository;
} else {
return repository;
}
}
}


After, I call it by:

PDMRepositorySelector.init();

The configure runs only once, why?
