Log4j not logging

eazyigz

Hi,
I have played with various settings in the log4j properties file. I've tried different logging levels also. Nothing is working! My application is not logging out anything.

If you ahve previously searched here for an answer... Try the sun site yet on this, couldn't hurt...

Care to also post your code:-)

You must've misconfigured the logging framework or you haven't configured it at all; read the short manual.

kind regards,

Ok, I managed to get it logging by playing around with values in the properties file. The original settings were as follows. Where it says ERROR, I added DEBUG and INFO.

Expand|Select|Wrap|Line Numbers

 log4j.debug = true

log4j.rootLogger=OFF

log4j.logger.com.iso.wc.fst=ERROR

log4j.logger.com.iso.framework=ERROR, FFILE, FSNMP

#################################### end of root and framework logger setting  #####################################

log4j.appender.FFILE=com.iso.framework.logging.ISOWebDailyRollingFileAppender

log4j.appender.FFILE.Directory=wdilogs

log4j.appender.FFILE.LogFile=FSTWebISOFramework.log

log4j.appender.FFILE.DatePattern='.'yyyy-MM-dd

log4j.appender.FFILE.layout=org.apache.log4j.PatternLayout

log4j.appender.FFILE.layout.ConversionPattern=- %-6p - | %d{yyyy-MM-dd HH:mm:ss.SSS} | [%t] | %C{1}.%M() | %m%n
 
log4j.appender.FSNMP=com.iso.framework.logging.SNMPAppender

log4j.appender.FSNMP.threshold=ERROR

log4j.appender.FSNMP.layout=org.apache.log4j.PatternLayout

log4j.appender.FSNMP.layout.ConversionPattern=- %-6p - | %d{yyyy-MM-dd HH:mm:ss.SSS} | [%t] | %C{1}.%M() | %m%n

log4j.additivity.com.iso.framework=false

#################################### end of framework appenders #####################################

My question is this: is it allowed to specify multiple logging levels at once? Also, I'm trying to understand the package hierarchy with respect to log4j.logger.com.iso.wc.fst and log4j.logger.com.iso.framework. How does this hierarchy work?

Thank you!

When you say specify multiple logging levels, do you mean for the specific message? Generally, if you are outputting WARN messages you're also outputting ERROR messages as well, so you can just put the output level to ERROR in this case. You can also just have multiple output statements for different log levels.

or do you mean something else entirely?

When I say multiple logging levels I mean specifying ERROR, DEBUG, TRACE, etc. all at once.
