Loggin exceptions

Hi,

I am facing a basic problem related to log4j.
I want to log exception stack traces which are useful for debugging.
In Throwable class
void printStackTrace() - prints into "System.err"
The remaining two prints into "PrintStream" or "PrintWriter".

how to use these methods to log using log4j.

Thanks in advance

Posted by doug b <um...@yahoo.com>.
the log4j methods debug, warn, error, etc.  have 2
signatures.  one takes just an Object, but one takes
both an Object and a Throwable.  if you call the one
that takes a Throwable, a stack trace will be logged.
