which version of tomcat are you using? i use tomcat 4, and all my stdout
logging goes to catalina.out.

i'm a log4j newbie but the attached custom appender works for me.
if you want to use it, then one way is to call from you servlet passing in
the context
Category.getRoot().addAppender(new ContextLogAppender(context));
if you want to use layout x, you need to set it before adding the appender
ContextLogAppender app=new ContextLogAppender(context);
app.setLayout(x);
Category.getRoot().addAppender(app);

that's a question that i'd like to know the answer to as well!
