Subject Re: Web demo example: Errors from Tomcat startup

I have no objection provided that:

1. Everything be kept simple enough for someone who is just getting
started to follow.  Don't forget that the getting started guide and
instructions assume you're using a pre-built lucene or know how to build
it.

2. You update the getting started guide to reflect the changes you
make.  (though we might not want to update the website since the
production version will be different)  -- (If you don't then I will but
I'd rather the person who makes the change update the docs so that they
are accurate and not my fuzzy understanding)..
