JavaMap(3) User Contributed Perl Documentation JavaMap(3) NAME Log::Log4perl::JavaMap - maps java log4j appenders to Log::Dispatch classes SYNOPSIS ############################### log4j.appender.FileAppndr1 = org.apache.log4j.FileAppender log4j.appender.FileAppndr1.File = /var/log/onetime.log log4j.appender.FileAppndr1.Append = false log4j.appender.FileAppndr1.layout = org.apache.log4j.PatternLayout log4j.appender.FileAppndr1.layout.ConversionPattern=%d %4r [%t] %-5p %c %x - %m%n ############################### DESCRIPTION If somebody wants to create an appender called "org.apache.log4j.ConsoleAppender", we want to translate it to Log::Dispatch::Screen, and then translate the log4j options into Log::Dispatch parameters.. What's Implemented (Note that you can always use the Log::Dispatch::* module. By 'implemented' I mean having a translation class that translates log4j options into the Log::Dispatch options so you can use log4j rather than log4perl syntax in your config file.) Here's the list of appenders I see on the current (6/2002) log4j site. These are implemented ConsoleAppender - Log::Dispatch::Screen FileAppender - Log::Dispatch::File RollingFileAppender - Log::Dispatch::FileRotate (by Mark Pfeiffer) JDBCAppender - Log::Log4perl::Appender::DBI SyslogAppender - Log::Dispatch::Syslog NTEventLogAppender - Log::Dispatch::Win32EventLog These should/will/might be implemented DailyRollingFileAppender - SMTPAppender - Log::Dispatch::Email::MailSender These might be implemented but they don't have corresponding classes in Log::Dispatch (yet): NullAppender TelnetAppender These might be simulated LF5Appender - use Tk? ExternallyRolledFileAppender - catch a HUP instead? These will probably not be implemented AsyncAppender JMSAppender SocketAppender - (ships a serialized LoggingEvent to the server side) SocketHubAppender ROLL YOUR OWN Let's say you've in a mixed Java/Perl environment and you've come up with some custom Java appender with behavior you want to use in both worlds, "myorg.customAppender". You write a Perl appender with the same behavior "Myorg::CustomAppender". You want to use one config file across both applications, so the config file will have to say 'myorg.customAppender'. But the mapping from "myorg.customAppender" to "Myorg::CustomAppender" isn't in this JavaMap class, so what do you do? In your Perl code, before you call Log::Log4perl::init(), do this: $Log::Log4perl::JavaMap::user_defined{'myorg.customAppender'} = 'Myorg::CustomAppender'; and you can use 'myorg.customAppender' in your config file with impunity.
