New subject: Using FileAppender to log within servlet not producing output

11 Mar 2012

      Hi,

I'm developing a Java web application through Tomcat with Java servlets. In my constructor for one servlet I call the following code:

public MyServlet () {
    // Initialise the logger
    logger = (Logger)LoggerFactory.getLogger("application");
    logger.debug("Starting application");
}

My logback.xml configuration file is the following:

<?xml version="1.0" encoding="UTF-8"?>

<configuration debug="true">

    <appender name="FILE"
        class="ch.qos.logback.core.FileAppender">
        <file>application.log</file>
           <append>true</append>

        <encoder>
            <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n
            </pattern>
        </encoder>
    </appender>

    <logger name="application" level="INFO">
        <appender-ref ref="FILE" />
    </logger>
</configuration>

When I launch the web app, the constructor is called by Tomcat, which should run the above code, but no file ("application.log") is created and no output is done anywhere.

Within the same project, I try to test the Logger. In a junit test I have the following:

public class TestLogging extends TestCase {
    public void testApplicationLogger() {
        // Initialise the logger
        Logger logger = (Logger)LoggerFactory.getLogger("application");
        logger.error("Starting application");
    }
}

This generates a file, a outputs "201  [main] ERROR application - Starting application"

Why can't I get the logger to output anything from the servlet?
