Custom exceptions and carrying forward stack trace

Question

Hi, I have a question on exception handling.
I have written an application which has several custom exceptions. When an exception occurs, sometimes I throw it and then when its caught, wrapping it in another exception like so:
} catch (Exception e){
throw new CollectionFailedException(this.getName() + " could not get collection", e);
This works fine, but when I output the stacktrace, it only goes as far as the new exception, making things more difficult to debug. Is there any way of incrementing the stack trace using the first exception?
Many thanks for any help offered!

Marc, this is expected behaviour. When you throw a new exception, the stacktrace starts off at the new one. A really nice explanation and sample code for creating new Exceptions and extending the Exception class is located at:
