Mark,
Thanks for the response.
Indeed I am using Log4j-2. Below is my xml file:
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="warn" name="SSP_App" packages="">
<appenders>
<RollingFile name="LogFile" fileName="/home/syed/logs/ssp-log.txt"
filePattern="/home/syed/logs/ssp-log-%d{MM-dd-yyyy}-%i.txt">
<PatternLayout>
<pattern>date:%d, millisecs:%r, level:%p, logger:%c, thread:[%t],
file:%F, method:%M, line:%L, message:%m%n%n</pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="50 MB"/>
</Policies>
<DefaultRolloverStrategy max="100"/>
</RollingFile>
</appenders>
<loggers>
<logger name="SSPLogger" level="ALL" additivity="false">
<appender-ref ref="LogFile"/>
</logger>
<root level="warn">
<appender-ref ref="LogFile"/>
</root>
</loggers>
</configuration>
And in my web app, I have the following statement that will set the system
property to where the above file is located at:
System.setProperty("log4j.configurationFile", "file://" + rootPath +
"/log4j-2.xml");
Thanks,
