log4j StringToMatch in property file

Question

I have following XML configration i would like to convert to java property file.

I am getting below error

log4j:WARN Failed to set property [filter] to value "org.apache.log4j.varia.DenyAllFilter". log4j:ERROR Could not instantiate class [true]. java.lang.ClassNotFoundException: true     at java.net.URLClassLoader$1.run(URLClassLoader.java:202)     at java.security.AccessController.doPrivileged(Native Method)     at java.net.URLClassLoader.findClass(URLClassLoader.java:190)     at java.lang.ClassLoader.loadClass(ClassLoader.java:307)     at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)     at java.lang.ClassLoader.loadClass(ClassLoader.java:248)     at java.lang.Class.forName0(Native Method)     at java.lang.Class.forName(Class.java:169)     at org.apache.log4j.helpers.Loader.loadClass(Loader.java:198)     at org.apache.log4j.helpers.OptionConverter.instantiateByClassName(OptionConverter.java:326)     at org.apache.log4j.PropertyConfigurator.parseAppenderFilters(PropertyConfigurator.java:881)     at org.apache.log4j.PropertyConfigurator.parseAppender(PropertyConfigurator.java:812)     at org.apache.log4j.PropertyConfigurator.parseCategory(PropertyConfigurator.java:735)     at org.apache.log4j.PropertyConfigurator.configureRootCategory(PropertyConfigurator.java:615)     at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:502)     at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:395)     at org.apache.log4j.PropertyConfigurator.configure(PropertyConfigurator.java:403)     at simpandfile.main(simpandfile.java:10) 

My XML configration

  <filter class="org.apache.log4j.varia.StringMatchFilter">     <param name="StringToMatch" value="FileNotfound" />     <param name="AcceptOnMatch" value="true" />   </filter>    <filter class="org.apache.log4j.varia.LevelRangeFilter">         <param name="LevelMin" value="ERROR"/>         <param name="LevelMax" value="FATAL"/>     </filter>    <filter class="org.apache.log4j.varia.DenyAllFilter"/> 

After converting the property file is as below. With XML configration it is working fine.

Property File

log4j.rootLogger=INFO, MAIL  log4j.appender.MAIL=org.apache.log4j.net.SMTPAppender # here's where I specify the layout and the pattern  log4j.appender.MAIL.BufferSize=1 log4j.appender.MAIL.SMTPHost=xxx.example.com [email protected] [email protected] log4j.appender.MAIL.Subject=Test Email. log4j.appender.MAIL.threshold=error log4j.appender.MAIL.layout=org.apache.log4j.PatternLayout log4j.appender.MAIL.layout.ConversionPattern=[%d{ISO8601}]%n%n%-5p%n%n%c%n%n%m%n%n log4j.appender.MAIL.filter=org.apache.log4j.varia.StringMatchFilter log4j.appender.MAIL.filter.StringToMatch=Filenotfound log4j.appender.MAIL.filter.AcceptOnMatch=true log4j.appender.MAIL.filter=org.apache.log4j.varia.DenyAllFilter   log4j.logger.com.devdaily.myapp=DEBUG log4j.logger.org.springframework=DEBUG
