My boss asked me that he want to use log4j(apache) only , but our project including quartz2.1.5 which must use slf4j.jar .
he think diffent log4j version made project messy, he only want to use log4j.
but when i remove slf4j than I can't run quartz.
Is any configration to set which log4j I want to use ?
I know quartz1.6 which doesn't need slf4j,but this version is too old to use.
