log4j報錯：
log4j:ERROR Could not find value for key log4j.appender.Console
log4j:ERROR Could not instantiate appender named "Console".
log4j:WARN No appenders could be found for logger (org.directwebremoting.util.Logger).
log4j:WARN Please initialize the log4j system properly.
配置中這麼寫：
log4j.rootLogger = DEBUG,Console
應該增加：Console
log4j.appender.Console= org.apache.log4j.DailyRollingFileAppender
log4j.appender.Console.File = /home/htmlfile/logs/ms.log
log4j.appender.Console.Append = true
log4j.appender.Console.DatePattern = '.'yyyy-MM-dd
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern = %d %-5p - [%l] - %m%n
主要是沒有在配置文件中定義造成初始化錯誤！
