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

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.
