Xerces xsd lookup in tapestry 5
Hi,
I've been playing with tapestry 5 a bit, and it's excellent. However,
due to our international line breaking down, accessing external
network resources is extremely slow to say the least. On every page
reload (if changed), parsing a tapestry 5 template (component or page)
that contains a reference to the tapestry namespace, takes a loooong
time, sometimes timing out. Seems xerces is trying to fetch the xsds
over the net. I've searched their FAQs, but it seems I need an
instance of the parser to switch validation off, so I'm wondering if
there is a way to do this in tapestry 5 without hacking the build.
This is the relevant part of the stacktrace I get:
java.net.UnknownHostException
Message:

Just ran the tests (over 500 of them) on the current code with my network
unplugged; no problems. I just switched the code over, yesterday, to use
XMLReader instead of SAXParser and based on your stack trace, you are
running the older version. Perhaps that's the difference.

I'll look into this. We should be intercepting requests for the XSD and
supplying them locally.
