Java - Need a logging package that will log the stacktrace

Question

Is there a Logger that will easily log my stacktrace (what I get with ex.printStackTrace())? I've searched the log4j docs and found nothing about logging the stacktrace.

I can do this myself with

StringWriter sw = new StringWriter();
ex.printStackTrace(new PrintWriter(sw));
String stacktrace = sw.toString();
logger.error(stacktrace);

but I don't want to duplicate this code all over the place.

If log4j won't do this for me is there another logging package that will log the stacktrace for me?

Thanks.

Using log4j this is done with:

logger.error("An error occurred", exception);

The first argument is a message to be displayed, the second is the exception (throwable) whose stacktrace is logged.

Another option is commons-logging, where it's the same:

log.error("Message", exception);

With java.util.logging this can be done via:

logger.log(Level.SEVERE, "Message", exception);
