Dear Wiki user,

ange notification.

Comment:
Remove "How do I use log4j for all Tomcat log output?" entry. The text was =
old and wrong. This topic is covered by Tomcat docs.

  No.  If you can edit Tomcat's startup scripts (or better create a {{{sete=
nv.sh}}} file), you can add "-D" options to Java.  But there is no way in J=
ava to have different values of system properties for different classes in =
the same JVM.
  =

  There are some other methods available, like using {{{ServletContext.getC=
ontextPath()}}} to get the context name of your web application and locate =
some resources accordingly, or to define {{{<context-param>}}} elements in =
{{{WEB-INF/web.xml}}} file of your web application and then set the values =
for them in Tomcat context file ({{{META-INF/context.xml}}}). See http://to=
mcat.apache.org/tomcat-7.0-doc/config/context.html .

- =3D=3D How do I use log4j for all Tomcat log output? =3D=3D
- To have Tomcat use log4j universally, place both `log4j.jar` and the Jaka=
rta `commons-logging.jar` into the `$TOMCAT_HOME/common/lib` directory.  Cr=
eate your log4j properties file as `$TOMCAT_HOME/common/classes/log4j.prope=
rties` and configure the root logger.  Here is the basic `log4j.properties`=
 that I used to do this myself:
- =

- {{{
- log4j.rootLogger=3Dinfo, R
- log4j.appender.R=3Dorg.apache.log4j.ConsoleAppender
- log4j.appender.R.layout=3Dorg.apache.log4j.PatternLayout
- log4j.appender.R.layout.ConversionPattern=3D%-5p %-30.30c{1} %x - %m%n
- }}}
- If you only need to use log4j in your own web app, just include log4j (an=
d any log4j properties file) in your WAR file.

  On the Tomcat FAQ, there is a list of Other Resources which should have i=
nformation pointing you to the relevant pages.
