Subject Re: Tomcat Won't start on NT

```This problem of running tomcat 4.1 and above, with JDK 1.4 and above has
been documented (and quite well too) at
(scroll down to the section "XML Parsers and JDK 1.4").

In essence, the conflict is caused by the built-in JAXP parser supplied with
JDK1.4 and the one you are trying to use for your application. You can still
use JDK 1.4 or above, but you'd need to set the parameter
http://java.sun.com/j2se/1.4/docs/guide/standards/index.html for more
information.
