log4j:ERROR with Tomcat 6 <p>I programmed a Web Application with Java EE. I am using log4j and Tomcat 6.0.28. When I am starting my app at tomcat following error message appears every 3 seconds at my console:</p> <pre><code>log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository. </code></pre> <p>Has somebody an idea what that means? Is there maybe a problem with log4j.xml? I can post more code/configfiles if nessecary. </p> <p>The application works, but I am a little bit worried. Thank you...</p>
