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 exception within the jsp page. Something like message and stack trace. In my jsp I've found the exception object in "exception" attribute. All I need to do is something like that:

${exception.printStackTrace()}

But I don't know how. Is there any way how to do that?:-)

Thanks for any suggestion,

Mateo

Answer 1

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.
