RE: [SPAM] Re: Custom log messages
Hi
You can prefix the categoy (package name) with the same prefix
To("log:com.mycompany.ValidatingAgainstXMLSchema")
To("log:com.mycompany.ValidationOK")
And have them logged in the same file
log4j.logger.com.mycompany = special
log4j.appender.special=org.apache.log4j.FileAppender
log4j.appender.special.layout=org.apache.log4j.PatternLayout
log4j.appender.special.layout.ConversionPattern=%d [%-15.15t] %-5p %-30.30c{1} - %m%n
log4j.appender.special.file=myspecial.log
log4j.appender.special.append=true

I'm not quite sure I follow. Claus's example uses a single Logger
called "ValidatingAgainstXMLSchema" or whatever. i.e. you can use a
single Logger if you want - the URI log:foo defines the logger to use.
There's not one per message or anything like that. Each different log
URI uses a different logger, so its up to you to define how many
different logger/categories you want to use.

Using this config tends to just print the last path of the category
log4j.appender.out.layout.ConversionPattern=[%30.30t] %-30.30c{1} %-5p %m%n
For more information see
http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html
i.e. use %c{x} where x is the number of right hand paths to print, so
%c{1} just prints the last one

Hi
You can do all sorts of thing with -% in log4j:
[%-15.15c]. I guess it should be possible to skip X.
Or you Can make your category very small, such as x ;
To("log:xValidatingAgainstSchma")

Yep, I just realised that was possible.
Do you know if there is a way to get rid of the full category name and only
print out the last token on the log file? i.e. print out
"ValidatingAgainstXMLSchema" instead of
"com.mycompany.ValidatingAgainstXMLSchema".
I am aware that I can truncate it at a fixed position, but I cannot
guarantee that my final tokens will all be the same length...

Yep, I just realised that was possible.
Do you know if there is a way to get rid of the full category name and only
print out the last token on the log file? i.e. print out
"ValidatingAgainstXMLSchema" instead of
"com.mycompany.ValidatingAgainstXMLSchema".
I am aware that I can truncate it at a fixed position, but I cannot
guarantee that my final tokens will all be the same length...
