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> <!-- <insertFromJNDI env-entry-name="java:app/AppName" as="appName" /> <contextName>${appName}</contextName> --> <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.
