Comment:
Correct version

  The Servlet Specification requires Servlet Containers like Tomcat to provide at least a
rudimentary implementation of the {{{ServletContext#log}}} method. Tomcat provides a much
richer implementation than required by the Spec, as follows:
  
   * Prior to Tomcat 5.5, Tomcat provided a Logger element that you could configure and extend
according to your needs.
-  * Starting with Tomcat 5.5, Logger was removed and [[http://commons.apache.org/logging/|Apache
Commons-Logging]] {{{Log}}} is used everywhere in Tomcat. Read the Commons-Logging documentation
if you'd like to know how to better use and configure Tomcat's internal logging. See also
http://tomcat.apache.org/tomcat-5.5-doc/logging.html
+  * Starting with Tomcat 5.5, Logger was removed and [[http://commons.apache.org/logging/|Apache
Commons-Logging]] {{{Log}}} is used everywhere in Tomcat. Read the Commons-Logging documentation
if you'd like to know how to better use and configure Tomcat's internal logging. See also
http://tomcat.apache.org/tomcat-8.0-doc/logging.html
   * In Tomcat 7 (and also 6), the logging code is based on a set of classes interacting with
the [[http://download.oracle.com/javase/6/docs/api/java/util/logging/package-summary.html|java.util.logging
API]] (JUL), which comes with Java since version 1.4. The Tomcat startup script configures
the JVM to use a web-application-aware implementation of the [[http://download.oracle.com/javase/6/docs/api/java/util/logging/LogManager.html|JUL
LogManager]]. This Tomcat logging infrastructure is called JULI, and one can still distinguish
its Apache Commons Logging heritage, but the complex configuration has been edited out and
the package name changed.
