Sorry for the double post, gmail pulled a trick on me :) Just ignore the other post.

Hi

I want to revisit this subject and theme. I saw that this thread ended 20th May 2008, but I did not find any conclusions on your discussion. The reason I find this subject interesting, is that I have use case which I can't seem to solve in any other way then setting a turbofilter on an appender.

This is situation:
One enterprise web application, which today uses a proprietary, home built, logging framework, logs statement to both file and to a database via an EJB. I have started the work to replace this logging framework with LogBack/SL4J.

Our new design would include file appender, and a jms appender which posts to a jms queue.

Example of log statements in the current solution:
<codeSnippet>           
                //The logger is the file logger
                logger.debug("Bar property was not defined in abc.properties");

                //FooLog is responsible for sending log message to the EJB
                LogContext lctx = new LogContext("webapplication", getClass().getName(), "theFooBarMethod()", LayerType.PRESENTATION);
                FooLog.log(logcontext, 6001, new String[] { "Bar property was not defined in abc.properties" }, null);
</codeSnippet>

This type of logging I want to change to this kind of logging:
<codeSnippet>
                logger.debug("Bar property was not defined in abc.properties");
</codeSnippet>

This is my use case:
We need to separate which log statements that goes to file and which goes to JMS (and eventually to database)

This is how I want to solve it:

This would only go to file
<codeSnippet>
                logger.debug("Bar property was not defined in abc.properties");
</codeSnippet>

But this would go to both file and jms
<codeSnippet>
                Marker JMS_MARKER = MarkerFactory.getMarker("JMS");
                logger.debug(JMS_MARKER, "Bar property was not defined in abc.properties");
</codeSnippet>

This could be obtained by doing something like this:

<appender name="Queue" class="com.a.b.c.log.CustomJMSQueueAppender">
    <InitialContextFactoryName>org.apache.activemq.jndi.ActiveMQInitialContextFactory</InitialContextFactoryName>
    <ProviderURL>tcp://localhost:61616</ProviderURL>
    <QueueConnectionFactoryBindingName>ConnectionFactory</QueueConnectionFactoryBindingName>
    <QueueBindingName>MyQueue</QueueBindingName>
   
    <turboFilter class="ch.qos.logback.classic.turbo.MarkerFilter">
      <Marker>JMS</Marker>
      <OnMismatch>DENY</OnMismatch>
    </turboFilter>
     
  </appender>

To end this; Is my use case covered in LogBack framework somehow, without waiting for this kind of features?
