preventing stack traces in log files
Is there a way to prevent stack traces from being placed in log files?
I guess the obvious would be to not pass Throwable objects to Log4J,
but is there another solution?

In this vein, I created an extended PatternLayout that added %s and %S
conversion characters; these gace "short" and "full" stack trace in
the output, if used.

This is how I did it some months ago (don't know if there's a more elegant
solution to this ;)
Basically, extend the PatternLayout (or whatever Layout you want to use
without stack traces) and
override the "ignoresThrowable()" method to make it return false - that
makes log4j think that your Layout will
indeed do something nice with the Throwable stack trace. Fact is, you don't,
so stack traces don't get shown.
Use this layout with the appenders you don't want stack traces in.
You could get fancier and change that false for a configurable field with a
getter and a setter - that way you can
alter in the log4j configuration if you want the stack traces or not.

I think the ConversionPattern determines if it is included. I thought
that removing ending "%n" took care of it. (I haven't tested and am
not sure).
