Remove log4j output
Hi,
I have a problem in using ARQ, always i have this message :
log4j:WARN No appenders could be found for logger
(com.hp.hpl.jena.sparql.mgt.ARQMgt).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for
more info.
I try to use a log4j.properties (provide here :
http://jena.apache.org/documentation/query/logging.html) and call this file
in my program with : PropertyConfigurator.configure ("log4j.properties");
As my first instruction, but that doesn't works.
How I can do for remove these messages ?
Thanks in advance.
Best regards.

Hi Andy,
I use ARQ as a library. And your advice works like a charm thanks a lot.
Best.

How are you running ARQ? From the command line or as a library?
Command line:
1/ This is fixed in the next release
2/ Put a log4j.properties in the current working directory
Library:
1/ Either set -Dlog4j.configuration on the java command
2/ Very early in your program, initialize the logging manually.
(before any logging code is called and any Jena code will cause logging
initialization) so before any Jena code is run
e.g. at the top of your main class:
static { Log.setLog4j() : }
and have a log4j.properties in the current directory.
