Hi Piotr,

Thanks for the reminder.
I did in fact do this, it had already been included in Thad’s solution.

The idea of my email was to describe changes I made to Thad’s code.
I now realize that it would have been smarter (and more useful to future 
mailing list readers) if I had included the rest as well.

So here’s my full web.xml.
Together with the LogListener.java I posted earlier, this achieves what I was 
trying to do.

Thanks as well for your two other suggestions.
This is very much appreciated.


With kind regards
