[logback-user] Use the stack trace rendering outside of logback

Really like the reverse stack trace rendering in logback and would like to leverage it (reuse it) in my app where I display the stack on an error web page. Can't seem to figure out how to get at just that function in the logback classes. Looking for something like String reverseStackRendering = LogbackExceptionUtils.renderInReverse(Throwable t) Or at least some public way to get at that function. Is that possible? Any pointers on where to start looking? Thanks, Padraic
