When I start my tomcat server, I get this error:

Apache Tomcat/4.0.6
PARSE error at line 1 column 1
org.xml.sax.SAXParseException: The markup in the document preceding the root element must be well-formed.

My server.xml and my web.xml appear to be correct, so in which file can I find this problem?

When I shut it down, I get another massage:

pricserv:/var/tomcat4/bin # ./catalina.sh stop
