title: Setting the log level to debug for a webapp in tomcat
body: <p>I have a webapp in tomcat for which I wish to set the log level to debug.
  I am not using JULI but log4j for the webapp.
  I have log4j-1.2.15.jar in the WEB-INF/lib folder and below is the log4j.properties file under WEB-INF/classes folder.</p>
  
  <pre><code>    log4j.rootCategory=INFO, Console
      log4j.logger.com.opensymphony.xwork2=INFO
      log4j.logger.freemarker.cache=INFO
      log4j.logger.org.apache.struts2=INFO
      log4j.logger.org.apache.xml.security=INFO
      log4j.logger.org.apache.commons.httpclient=INFO
      log4j.logger.org.mortbay.log=INFO
      log4j.logger.net.sf.ehcache=OFF
      log4j.appender.Console=org.apache.log4j.ConsoleAppender
      log4j.appender.Console.encoding=UTF-8
      log4j.appender.Console.layout=org.apache.log4j.PatternLayout
      log4j.appender.Console.layout.ConversionPattern=%d{dd MMM HH:mm} %c{1} %-5p - %m%n
  </code></pre>
  
  <p>and in the class files I get the handle like this...</p>
  
  <pre><code>    public static Log log = LogFactory.getLog(Crossword.class);
  </code></pre>
  
  <p>Where Crossword is a class in the webapp.
  I can see the INFO level logs being logged to muse.log in the tmp directory, now what changes do I need to make for it to log at DEBUG level.
  Thank you.</p>
