If somebody wants to create an appender called \f(CW\*(C`org.apache.log4j.ConsoleAppender\*(C'\fR,
we want to translate it to Log::Dispatch::Screen, and then translate
the log4j options into Log::Dispatch parameters..
.SS "What's Implemented"
.IX Subsection "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.)
.PP
Here's the list of appenders I see on the current (6/2002) log4j site.
.PP
These are implemented

.SH "ROLL YOUR OWN"
.IX Header "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, \f(CW\*(C`myorg.customAppender\*(C'\fR.  You write a
Perl appender with the same behavior \f(CW\*(C`Myorg::CustomAppender\*(C'\fR. You
want to use one config file across both applications, so the
config file will have to say 'myorg.customAppender'.  But
the mapping from \f(CW\*(C`myorg.customAppender\*(C'\fR to \f(CW\*(C`Myorg::CustomAppender\*(C'\fR
isn't in this JavaMap class, so what do you do?
.PP
In  your Perl code, before you call \fILog::Log4perl::init()\fR, do this:
.PP
.Vb 2
\&    $Log::Log4perl::JavaMap::user_defined{\*(Aqmyorg.customAppender\*(Aq} = 
\&        \*(AqMyorg::CustomAppender\*(Aq;
.Ve
.PP
and you can use 'myorg.customAppender' in your config file with
impunity.
