o.a.c.logger.SystemOutLogger and o.a.c.logger.SystemErrLogger do the opposite 
of what you want. They direct all ServletContext.log() for a specific Context 
to the Catalina's standard output or standard error output respectively.

Like I said I believe you can't cheat System.out.print() into working like 
ServletContext.log(), which gives you the convinience of per-Context Loggers. 
You can only change the entire Tomcat engine's standard (error) output to a 
destination other than $CATALINA_HOME/logs/catalina.out as laid out in my 
previous message.

You may have to write a Perl script or use sed (or a Windows equivalent, if 
any) to replace every occurance of System.out.print()/println() with calls to 
a good logging API like commons-logging or log4j.
