[kaffe] Problem with Strings/Xml Parsing while trying to run an embedded Jetty

[Rafael Teixeira]

Thank You, Ito.

I think you've found the right spot on my second problem. Thank you
for your time: I will set org.mortbay.xml.XmlParser.NotValidating to
true, as the web application is fixed and embedded in the same big jar
as jetty and all the other components.

Thank you, again
