log4jWeb アプリでセットアップしようとしています。ウェブサーバーはTomcat 7.
次の例外が発生します。

多くのSOユーザーが他の質問に対する他の回答で提案したようlog4j.propertiesに、ディレクトリに入れました。WEB-INF/classes
slf4j-api-1.7.5.jar、、slf4j-log4j12-1.7.5.jarをディレクトリに入れlog4j-1.2.16.jarました。WEB-INF/lib
私のプロパティファイルは次のとおりです。
log4j.rootLogger = INFO,infoAppender,errAppender
log4j.appender.infoAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.infoAppender.File= D://logs//info//info.log
log4j.appender.infoAppender.DatePattern='_'dd-MM-yyyy
log4j.appender.infoAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.infoAppender.layout.conversionPattern=%d{dd-MM-yyyy HH:mm:ss} %5p %m%n
log4j.appender.infoAppender.filter.infoFilter=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.infoAppender.filter.infoFilter.LevelToMatch=INFO
log4j.appender.infoAppender.filter.infoFilter.AcceptOnMatch=true
log4j.appender.infoAppender.filter.2=org.apache.log4j.varia.DenyAllFilter
log4j.appender.errAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.errAppender.File= D://logs//error/err.log
log4j.appender.errAppender.DatePattern='_'dd-MM-yyyy
log4j.appender.errAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.errAppender.layout.conversionPattern=%d{dd-MM-yyyy HH:mm:ss} %5p %m%n
log4j.appender.errAppender.filter.errFilter=org.apache.log4j.varia.LevelMatchFilter
log4j.appender.errAppender.filter.errFilter.LevelToMatch=ERROR
log4j.appender.errAppender.filter.errFilter.AcceptOnMatch=true
log4j.appender.errAppender.filter.2=org.apache.log4j.varia.DenyAllFilter
私は個人的に問題はクラスパスのような問題にあると思いますが、すべての .jar ファイルと .properties ファイルは正しい場所にあります。少なくとも、私が見つけた多くの関連記事によると、それは正しいです。
