    Upgrade from 4.2.3 to 5.1 - log4j issue

    Cosmin Mendrea Newbie

      Hi,

       

      We are trying to upgrade from JBOSS 4.2.3 to 5.1 but we are having problems with log4j. We have log4j.xml and log4j.jar bundled in each EAR. log4j.jar is in the lib folder and log4j.xml & log4j.dtd are in the EAR root. The log4j.xml file contains a Console and a custom RollingFileAppender appenders. The file appender is configured to output into ${jboss.server.home.dir}/logs/Filename.log. In each EAR we pack an EJB. This worked nicely in 4.2.3: the log file was being created and the logs generated by the EJB were written into the file. But this no longer works in JBOSS 5.1. The first time we invoke the EJB, we get the following in Eclipse's console and nothing is written into the log file (also, nothing appears anymore in Eclipse's console):

      FYI, we are using the standard server.

       

      Can you give us a clue? Should this be working in JBOSS 5.1 or is it a bug?

       

      Thank you,

          This is the second thread in recent weeks about this issue. I haven't had time to try this out in AS 5.1. I know it used to work with AS-4.x. Let me give it a try locally (might take a couple of days) and see what the issue is. I'll update this thread once I figure out what's wrong. In the meantime if someone else finds out the problem, feel free to update this thread.

            Just a follow up: if inside the EAR we package only a WAR and we access a servlet, logging works as expected:
