Examples with Logger java.util.logging.Logger used on opensource projects

Example 66 with Logger

use of java.util.logging.Logger in project tomcat by apache.

the class Tomcat method setSilent.

/**
     * Controls if the loggers will be silenced or not.
     * @param silent    <code>true</code> sets the log level to WARN for the
     *                  loggers that log information on Tomcat start up. This
     *                  prevents the usual startup information being logged.
     *                  <code>false</code> sets the log level to the default
     *                  level of INFO.

Example 70 with Logger

use of java.util.logging.Logger in project jmonkeyengine by jMonkeyEngine.

the class TestChatClient method main.
