This is one of the reasons why I designed the Dash framework. It essentially
wraps all of your "servlets" into a single servlet. Your "sub servlets"
throw all their exceptions to the top servlet. If you look at the Dash.java
file, you will see that in the doGet() method, it catches all Exceptions and
attempts to display an error screen that contains the stacktrace nicely
printed.
Here is a url for the code:

One way to simply catch the exceptions into a String is to do something like
this:
ByteArrayOutputStream ostr = new ByteArrayOutputStream();
e.printStackTrace(new PrintWriter(ostr,true));
String stackTrace = ostr.toString();
