When I check my service console, I come across some errors with my log4j. my log4j is below

    log4j.rootLogger=INFO, R

#log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
#log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
#log4j.appender.CONSOLE.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}:%L] %m%n


log4j.appender.R = org.apache.log4j.RollingFileAppender 
log4j.appender.R.File = "DataSourceFactory.log" 
log4j.appender.R.Append = true 
log4j.appender.R.MaxFileSize=10MB 
log4j.appender.R.MaxBackupIndex=1000 
#log4j.appender.R.DatePattern = '.'yyy-MM-dd 
log4j.appender.R.layout = org.apache.log4j.PatternLayout 
log4j.appender.R.layout.ConversionPattern =%d{yyyy-MM-dd HH:mm:ss} %t/%c{1} [%p]

Am trying to run tomcat as a server. how to I get rid of the error. is my log4j correct? am really new in this, please can someone help. thanks

Answer 1

User that stated tomcat has no permission to write to /opt/igr-tomcat/logs/. Change the permissions of this directory with chmod ... or the owner chown ...
