Error Page - how to print stack trace in JSP

Question

I\'ve created exception handling in my Spring application using spring SimpleMappingExceptionResolver. Everything works fine. Now I need to somehow print the caught exceptio

Answer 1

Had to do this (dev/local environment only) in pages in the past and just want to display it in a textarea or a preformatted block. The output from skaffman prints out each strack trace element but not the message and exception class.

If you want it pre-formatted as per a printStackTrace() consider using Spring EL and commons-lang3.

<spring:eval expression="T(org.apache.commons.lang3.exception.ExceptionUtils).getStackTrace(exception)"/>

Answer 2

The easiest solution I can think of is to loop over the stack trace elements, taking advantage of the Throwable.getStackTrace() method:

<c:forEach items="${exception.stackTrace}" var="element">
    <c:out value="${element}" />
</c:forEach>

You'd need to add some formatting, of course.
