can I use a Logger for writing debug statements?

[John Holme]

can I write debugging statements in a jsp or servlet that will appear in one of the log files associated with a "Logger" entry in server.xml?
for example, I have the following entry for a Logger in server.xml, associated with a particular context:
<Logger className="org.apache.catalina.logger.FileLogger" prefix="imf_catali
na." suffix=".log" timestamp="true" verbosity="4"/>
what syntax should I use in a jsp to write a debugging statement that will appear in the logfile associated with this logger entry?
do Loggers even support this type of functionality, or is this why I need Log4J?
thanks,
John

ok, guys, I finally figured this one out myself:
the log() method of ServletContext can be used to write messages to the log file designated by the operative Logger object designated in server.xml. (Loggers can be defined at various levels of the Tomcat environment, including Context, Host and Engine. A logger defined at a lower level supplants one defined at a higher level.)
in a jsp, you can get the ServletContext and call it's log() method as follows:
ServletContext context =
getServletConfig().getServletContext();
context.log("LOG_MESSAGE");
as of Servlets 2.1, the ServletContext.log() method has 2 signatures:
log(java.lang.String message) AND
log(java.lang.String message, java.lang.Throwable throwable)
