I just used the basic configurator which should just log to catalina.out, right?
But still nothing gets logged (I do get a warning about No appenders could be
found) Here is the code:
public class TestServlet extends HttpServlet {
private static Logger logger;
public TestServlet() {
BasicConfigurator.configure();
logger =
Logger.getLogger(GenerateChartServlet.class.getName());
}
private void doPost(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException
{
...
// This never gets outputted to log file
logger.debug("TestServlet: debug");
logger.warn("TestServlet: warn");
logger.info("TestServlet: info");
...
}
}
#
# Output from catalina.out
