log4j代码设置错误

[chaohua20]

fileAppender = new DailyRollingFileAppender();
		fileAppender.setName("container-file");
		fileAppender.setAppend(true);
		fileAppender.setLayout(normalLayout);	

上面用代码设置log4j结果出现如下问题

log4j:WARN File option not set for appender [container-file].
log4j:WARN Are you using FileAppender instead of ConsoleAppender?
log4j:ERROR Either File or DatePattern options are not set for appender [container-file].
