hi guys,

I try to configure logback for our application in glassfish (3.1) as follows:

[*] I start gf with -Dlogback.configurationFile=/path/to/file

[*] logback.xml is:
<configuration>

<appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <file>../logs/r6.log</file>
    <encoder>
      <pattern>%date %-5p [%thread] [%contextName] [%logger{20}] %msg%n</pattern>
    </encoder>
</appender>
<root level="debug">
    <appender-ref ref="FILE" />
</root>
</configuration>

So far everything works fine. However I encountered a problem in the following situation.

[*] A simple message driven bean, which is invoked if there are new messages in a given "jms-queue" like this:
@MessageDriven( mappedName="myQueue", activationConfig = {
    @ActivationConfigProperty(propertyName = "acknowledgeMode",
                              propertyValue = "Auto-acknowledge"),
    @ActivationConfigProperty(propertyName = "destinationType",
                              propertyValue = "javax.jms.Queue")
})
public class MyMdb implements MessageListener {

    private static Logger logger = LoggerFactory.getLogger(MyMdb.class);

    @Override
    public void onMessage(Message msg) {
        logger.info("got message...");
    }
}

[*] Glassfish is not running, AND there ARE messages in the queue
[*] Now when I start glassfish the application (MyMdb) start receiving the messages from the queue
[*] At this point logback is not yet initialized, as I see the following messages in my logfile:

The following loggers will not work becasue they were created during the default configuration phase of the underlying logging system. See also http://www.slf4j.org/codes.html#substituteLogger

Any ideas how to solve this?
