Error page - stack trace highlighting

[Harry Wood]

I want my JSP error page to show a stack trace with some intelligent HTML formatting to highlight the important bits. Googling for error page examples, all I can find is basic examples for outputting a plain old stacktrace like this:

  
<p> An exception was thrown: <b> <%= exception %>
<p> With the following stack trace:
<pre>
<%
    ByteArrayOutputStream ostr = new ByteArrayOutputStream();
    exception.printStackTrace(new PrintStream(ostr));
    out.print(ostr);
%>
</pre>

So I guess I want to get hold of the each line of the stack trace as a string, and output it line-by-line after adding some HTML decorations. How do I do that with the various java Streams and PrintWriter objects? ...and more to the point... hasn't someone out there done this before??? Know any URLs for advanced example error pages?

Since I never show a stack trace to an end user, I've never felt the need to decorate it.
Check out the StringWriter class to capture the trace into a string.
