log4j error
Hello
I have installed and importe Jena 2.10. When I run my program, it gives me
the error:
WARN No appenders could be found for logger
(com.hp.hpl.jena.sparql.mgt.ARQMgt).
log4j:WARN Please initialize the log4j system properly.
I have included the "properties" file with the following code, but still it
gives me the error.
log4j.rootLogger=INFO, stdout
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p

By import I mean include the file.
I have included the file with the following code:
log4j.rootLogger=INFO, stdlog
## log4j.rootLogger=INFO, FusekiFileLog
log4j.appender.stdlog=org.apache.log4j.ConsoleAppender
## log4j.appender.stdlog.target=System.err
log4j.appender.stdlog.layout=org.apache.log4j.PatternLayout
log4j.appender.stdlog.layout.ConversionPattern=%d{HH:mm:ss} %-5p %-20c{1}
:: %m%n
## # Example for file logging.
## log4j.appender.FusekiFileLog=org.apache.log4j.DailyRollingFileAppender
## log4j.appender.FusekiFileLog.DatePattern='.'yyyy-MM-dd

## log4j.appender.FusekiFileLog.layout=org.apache.log4j.PatternLayout
## log4j.appender.FusekiFileLog.layout.ConversionPattern=%d{HH:mm:ss} %-5p

Log4j initializes very early (use -Dlog4j.debug).
It must be initialised before calling any Jena code except Log.setLog4j
(and that looks for file "log4j.properties", nothing else).
Use -Dlog4j.configuration
(Jena 2.10 is 5 years old)

I have already imported Jena-4jlog.properties, but still it gives the error.

The message means log4j1 can't find a logging setup.
Add the appropriate "-Dlog4j.configuration=file:..." to the java
invocation.
Add "-Dlog4j.debug" to debug.
See the log4j documentation.
