Create new log file daily using log4j

问题

I want to use Log4j in my java project, which configuration should I provide in configuration file that every night at 12.00 am new file will generate and file name should like - output-log-of-MyProjectName-HostName-2013-Dec-10.txt name). My configuration file is like that-

log4j.appender.FILE = org.apache.log4j.DailyRollingFileAppender    
log4j.appender.FILE.File = ${log}/log.out    
log4j.appender.FILE.DatePattern = '.' yyyy-MM-dd-a

It is creating new file everyday but it appending date after file name. Please help me. Thanks in advance.
