Hi,

i'm trying to switch to Log4j from Logback.

In the configuration (the file appender), i'm using a system property that does not exist and is created in the contextListener (the logs path is generated at runtime and can't be set staticly in the config file)
{code:java}
<configuration debug="true">

 <contextListener class="it.my.LoggerStartupListener"/>

 <appender name="JSON" class="ch.qos.logback.core.rolling.RollingFileAppender">
  <File>${LOG_PATH}/app.log</File>
 <FileNamePattern>${LOG_PATH}/app.%d{yyyy-MM-dd}.%i.log.gz
 </FileNamePattern>
...{code}
{code:java}
public class LoggerStartupListener extends ContextAwareBase implements LoggerContextListener, LifeCycle {

 private static final String LOG_PATH = "LOG_PATH";

 @Override
 public void start() {
    getContext().putProperty(LOG_PATH, Paths.get(OSUtils.getBasePath(), "logs").toString());
  }
}{code}
