For FioranoMQClientRTL logging to take place, the logger levels and appenders have to be mentioned through properties file or xml file. The jboss application server uses log4j.xml file. In this case, the FioranoMQClientRTL loggers' level and appender has to be mentioned in the same log4j.xml.
Example: If the logger name is "Fiorano.FMQ.Services.ClientRootLoggerServices.FMQClientLoggerServices", the logger level is INFO and the log appender is RollingFileAppender, then
log4j.properties file will contain the logger names used in FioranoMQClientRTL. By default, "log4j.properties" file will be provided under %FIORANO_HOME%\fmq\bin.
