Subject Re: A question about log-rotation on "catalina.out"
Date Thu, 29 Oct 2009 22:47:56 GMT

1) :-)
2) I'll definitely try it.  It looks like it's worth the effort (and as 
a reward for yours).
3) I have a question in the text below
4) If it works, this has got to go on the WiKi

No, I don't want to learn log4j. It looks too much like lifelong 
dedication is needed, just like Java (*). I am not an intensive Java 
programmer.  I'm an intensive Perl programmer.  I kind of like Java to 
look at.  And I try to keep a veneer of knowledge about it and Tomcat, 
just to keep these younguns in meetings from thinking they can impress 
me into submission.

and elegant.  But it's that in order to do anything at all in that 
language, you first need to become familiar with dozens of class
