Using log4j.properties to handle other properties
My developers are using System Properties to enable certain trace options
(like collecting statistics)
Is there a way I could define such property in the log4j.properties instead
so we keep trace/log options and metadata together ?
So my developers will do
<aLog 4J object>.getProperty('my property') instead of System.getProperty()
?

The receiver can handle multi-line messages, but it isn't foolproof. If
there's a choice, using XMLLayout will give you more predictable results.

LogFilePatternReceiver will do this...you'd have to write a simple appender
that processes the events the are generated by the receiver. Both your
appender and the receiver need to be added to the log4j configuration file.

you could, but you still have the problem of handling multi-line messages.
if you have the option to change layout, xmllayout is pretty foolproof...

Hey Doug,
Yes I agree
I was thinking I could use the same ConversionPattern
So if my log4j properties lists
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} [%t] %5p
%-50.50c - %m%n
it would use the ConversionPatten as a regex and read each line ??
am I dreaming ? :)

doing this with an arbitrary layout would be quite daunting.
if you use XMLLayout, then reading the XML and doing what you want would
be quite simple.

import log into java model using log4j.properties
Posted by Christophe Elek <ce...@ca.ibm.com>.
I am looking for a solution that would do the 'reverse' of logging into a
log file: reading a log file into java obects.
I want a tool that would take a log4j.properties, a log generated using
this log4j.properties and would transform each event into an object
Then I can run an analyzer :)
Does it make sense ? :)
