OP never posted the whole XML, so we don't know that it's definitely
not well-formed.
Tomcat definitely bombs if the document isn't well-formed:
Nov 30, 2012 5:08:28 PM org.apache.tomcat.util.digester.Digester
endElement
WARNING: No rules found matching 'Server/Service/Engine/Host/Host'.

org.xml.sax.SAXParseException; systemId:

If the OP was using an XML editor (again, without any Schema or DTD),
it might have let him (or even auto-fixed the structure to) do this:
<Service>
<Engine>
<Host>
<Host>
</Host>
</Host>
</Engine>
</Service>
This message would have showed up in catalina.out:
Nov 30, 2012 5:11:47 PM org.apache.tomcat.util.digester.Digester
endElement
WARNING: No rules found matching 'Server/Service/Engine/Host/Host'.
...but such a thing is easy to miss.
