Syslog message is sent twice in the case no log4j configuration file is used

["Berwanger, Christian" <ch...@logica.com>]

Hi log4j comunity,

 

I'm using the log4j appender in order to send my log message to a remote
host. I decided not to use the config file because the application
itself is already using a central config file which I want to use to
read my configurable data (like hostname, port...). However when I'm
using the log4j API without config file the message is sent twice times.

 

I read and tried already the hints on the tutorial sites without success
which threads several ideas for the problem of multiple same messages. 

 

 m_logger = Logger.getLogger(SecurityEvent.class.getName());

 m_logger.setAdditivity(false);

 m_syslogAppender = new SyslogAppender();

 m_syslogAppender.activateOptions();

 m_syslogAppender.setLayout(new PatternLayout("%c: %m%n"));

 m_syslogAppender.setSyslogHost("localhost");

 m_logger.addAppender(m_syslogAppender);

 m_syslogAppender.setFacility(mapFacilityID(this.m_facility));

 sendLogMessage(logMessage);

 m_logger.removeAllAppenders();

 

However when I tried following configuration file instead it worked
fine.

 

# Set root logger level to DEBUG and its only appender to A1.

log4j.rootLogger=DEBUG, A1

 

# A1 is set to be a ConsoleAppender.

log4j.appender.A1=org.apache.log4j.net.SyslogAppender

 

# A1 uses PatternLayout.

log4j.appender.A1.layout=org.apache.log4j.PatternLayout

log4j.appender.A1.SyslogHost=localhost

 

log4j.appender.A1.layout.ConversionPattern=%c: %m%n

 

 

How can I get only ONE log message?

 

Thanks for all help

 

Christian
