    Error when logging inside EJB s

    Marco Novice

      hi all,
      i am having troubles iwth logging with jboss 4.0.4.GA..
      I have deployed (successfully) few EJBs in an .ear file on jboss-4.0.4
      all my ejbs and web action classes use log4j for logging (i have my own log4j.properties file).
      what happens is that whenever i run my application, log is fine on the web, but whenever i call an ejb, the console hangs giving me back this message

      ERROR: invalid console appender config detected, console stream is looping
      


      in one of ejbs, i have tried to replace log4j with System.err callls and it works just fine..
      since my logger works in my web project, i have excluded it from being cause of probblems.
      So, the trouble is that i cannt do logging in my ejbs... can anyone tell me why?
      are there any settings i need to modify?
      can anyone help?

      thanks in advance and regards
      marco

          Post your log4j.conf? Looks like you have a circular reference in there, like you have an appender containing an "appender-ref" calling itself or something similar...

            hello,
            here they are..
            it looks like (from logs), jboss is using log4j.properties which is embedded in my jar file

            here it is

            #
            # Set the redbook EJB code priority to DEBUG
            #

            #
            # NGEN_LOG_FILE is a FileAppender that appends to logs\ngenTrace.log
            #
            log4j.appender.NGEN_LOG_FILE=org.apache.log4j.RollingFileAppender
            log4j.appender.NGEN_LOG_FILE.File=ngenTrace.log
            
            log4j.appender.NGEN_LOG_FILE.MaxFileSize=100000KB
            
            # Keep one backup file
            log4j.appender.NGEN_LOG_FILE.MaxBackupIndex=1
            
            log4j.appender.NGEN_LOG_FILE.layout=org.apache.log4j.PatternLayout
            
            ###########################################################################
            # DO NOT CHANGE THIS!
