I changed as said...but still have the same problem..it creates a logfile
but no messages in the file...
log4cxx::FileAppenderPtr fileAppender(new
log4cxx::FileAppender(log4cxx::LayoutPtr(new
log4cxx::SimpleLayout()),log4cxx::helpers::Transcoder::decode(logfile.c_str()),false));
log4cxx::LoggerPtr logger = log4cxx::Logger::getLogger("logger");
log4cxx::BasicConfigurator::configure();
logger->setLevel(log4cxx::Level::getAll());
logger->addAppender(fileAppender);
logger->info("APPS INITIALIZED");
LOG4CXX_INFO(logger,"IN main method");
logger->trace("tracing");
fileAppender->close();
printf("\n file name : %s","got here");
am i missing something...please let me know...
thanks in advance
