AW: Newbie questions
If you do not specify any appender, your log message will go nowhere. Please read first the basics about log4j, before asking such dumb questions.

Re: AW: Newbie questions
Thanks for your no help at all. There is no appender, and I've found the log by running grep over all the likely files, and by grepping that file name I've found where the log file is set. I've searched the documentation for this kind of set up and found nothing. I've found info on properties files and the most useful thing I've found about using an xml file for log4j configuration was a blog where the guy says that there doesn't seem to be a good source of info on this. My questions may have been dumb, but you weren't smart enough to provide an answer. I can't imagine why you bothered to reply to my post if you had nothing of value to add. Lots of spare time? A feeling of superiority when you call my question dumb? Can't be that because you don't seem superior enough to have an answer. One more dumb question for you. If you're so smart, where did I find the set up for the fatal log? And why? I know the answers now, but do you?

Re: AW: Newbie questions
One more dumb question for you. If you're so smart, where did I find
the
set up for the fatal log? And why?
I would have had to agree with Bender's statement that logging with no
appenders makes the logging go nowhere, and I put together a test case to
make sure:
the program:
import org.apache.log4j.Logger;
public class TestNoAppenders {
public static void main (String[] args) {
System.setProperty(log4j.debug, true);
System.setProperty(log4j.configuration,
file:log4j-noappender.xml);
Logger logger = Logger.getLogger(foo);
logger.info(hello);
}
}
the configuration:
?xml version=1.0 encoding=UTF-8 ?
!DOCTYPE log4j:configuration SYSTEM log4j.dtd
log4j:configuration xmlns:log4j=http://jakarta.apache.org/log4j/; debug=
true
root
priority value=INFO /
/root
/log4j:configuration
The output to stdout/stderr:
log4j: Using URL [file:log4j-noappender.xml] for automatic log4j
configuration.
log4j: Preferred configurator class: org.apache.log4j.xml.DOMConfigurator
log4j: System property is :null
log4j: Standard DocumentBuilderFactory search succeded.
log4j: DocumentBuilderFactory is:
org.apache.crimson.jaxp.DocumentBuilderFactoryImpl
log4j: debug attribute= true.
log4j: reset attribute= false.
log4j: Threshold =null.
log4j: Level value for root is [INFO].
log4j: root level set to INFO
log4j:WARN No appenders could be found for logger (foo).
log4j:WARN Please initialize the log4j system properly.
which is exactly what experience has lead me to expect (I have seen the
last two lines about a bajillion times in my life...), and Bender's
statement is quite accurate for the information given...
so now my curiousity is up: where *did* you find your output? if it showed
up anywhere, I would be inclined to think that a different configuration
was getting picked up...
Re: AW: Newbie questions
Don't get bent out of shape when you decide to post this kind of question to a public forum and you get the kind of response you did. A lot of people monitor these forums to pick up information, to get help with problems, and/or help people with legitimate. It's quite understandable why people get irritated at those that can't be bothered to do a bit of homework to discover basic information. Too much of this kind of noise discourages knowledgeable people from monitoring these forums. RTFM next time and save this forum for non-trivial questions.
