Redirect stack trace to a string

Hi !

I would like to be able to log for an exception, not only the e.getMessage()
but the whole e.printStackTrace(). Does anybody know how to redirect
temporarily the standard out to a string ?

Ideal would be such a function :
- store the standard out
- change the standard out to a string reader
- execute the e.printStackTrace()
- log the output string
- restore the standard out

Thank you for your help

Best regards

You don't need to do that. Just attach a StringWriter to a PrintWriter and
use the appropriate e.printStackTrace().
