Question

I’m currently migrating old web apps from JBoss As 4.2.2 to 6.0.0 (AS6). In AS6 we have a proprietary format for logging applications through a file named jboss-logging.xml.

After read some stuff (http://community.jboss.org/wiki/SeparatingApplicationLogs) reach the conclusion that “(…)starting with JBoss AS 6.0.0.M2 the ability to log to separate log files, per application, will be implemented in a different way” and also that the documentation “(…) will be updated with more details, once the implementation is ready”.

However I was able to create the specific application log files in my server/log dir, it was done using the main joboss-logging.xml file in the server/deploy dir. This is not compatible with the modularity my applications demand.

So here the problem when I create a jboss-logging.xml e my WEB-INF dir for my app whit this configuration:

<?xml version="1.0" encoding="UTF-8"?>
<logging xmlns="urn:jboss:logging:6.0" xmlns:b="urn:jboss:bean-deployer:2.0" context="myApp">
   <define-context name="myApp" />

   <periodic-rotating-file-handler
         file-name="${jboss.server.log.dir}/myApp.log"
         name="WEBAPP" autoflush="true" append="true" suffix=".yyyy-MM-dd">
      <error-manager><only-once/></error-manager>
      <formatter>
         <pattern-formatter pattern="%d %-5p [%c] (%t) %s%E%n"/>
      </formatter>
   </periodic-rotating-file-handler>

   <root-logger>
      <!-- Set the root logger priority via a system property, with a default value. -->
      <level name="${jboss.server.log.threshold:INFO}"/>
      <handlers>
         <handler-ref name="WEBAPP"/>
      </handlers>
   </root-logger>

</logging>

I get the following error when my app starts:

8:57:07,765 ERROR [AbstractKernelController] Error installing to Configured: name=Logging:REGISTRATION:myApp:Anonymous-0 state=Instantiated: java.lang.RuntimeException: Error configuring property: selector for Logging:REGISTRATION:myApp:Anonymous-0

I will be grateful for any kind of info or direction on this subject, even one that represents using a complete different approach to logging in AS6. Although I feel I’m getting closer to the solution… Thank you in advance.

This is a bug, it’s reported here:
https://issues.jboss.org/browse/JBLOGGING-56

I tried the workaround that they mention, but couldn’t get it to work either. Unfortunately, new logging framework in JBoss AS 6 seems to be very buggy and undocumented at this moment.
