Placing log4j's JAR into jre/lib/ext didn't cause the logs to appear. (I
should mention that the logs I'm trying to control with log4j are Tomcat's
internal logs, rather than web application logs.) The following command from
the command line outputs the log as expected, as does calling startup.bat,
or catalina.bat run:
java -cp "tomcathome\bin\bootstrap.jar"
-Dcatalina.base="path/to/catalina/base"
-Dcatalina.home="path/to/catalina/home"
org.apache.catalina.startup.Bootstrap start
The logs aren't created, however, when starting Tomcat from within an IDE
(Eclipse), in the following two cases:
- The Tomcat plugin that points to the same tomcathome as in the
command-line snippet above
- The main method of a class that uses the Bootstrap class, in the following
way:
Bootstrap bootstrap = new Bootstrap();
bootstrap.setCatalinaHome(System.getenv("CATALINA_HOME"));
bootstrap.setCatalinaBase(System.getenv("CATALINA_BASE"));
bootstrap.init(new String[] { "-config", "path/to/server.xml" });
bootstrap.start();
