I am having problems getting log4j appenders initialized. I am doing this via a properties file. So all I code in my java compute node is the getLogger. I have the following properties file. Where does this have to be stored so the classloader can find it when running my message flow?

I get the standard warning about no Appenders.

I also tried using XML and deploying with my bar file. This did not work either. Of course I don't know if the XML log4j file is correctly coded.

log4j.properties
---------------------

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG,A1

# A1 set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender
# A1 is set to be a FileAppender.
#log4j.appender.A1=org.apache.log4j.FileAppender
#log4j.appender.A1=org.apache.log4j.RollingFileAppender

# A1 uses a file.
#log4j.appender.A1.file=C:\\mylog4jfile.log

# For RollingFileAppender, don't append, overwrite
#log4j.appender.A1.Append=false

# For RollingFileAppender, control the maximum log file size
#log4j.appender.A1.MaxFileSize=100MB

# For RollingFileAppender, keep backup files (backups will be name in filename.1, .2, etc)
#log4j.appender.A1.MaxBackupIndex=3

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n
