Problems with tomcat 4.1.18 - migration from tomcat 3.2.1

[tradester amagio]

Im having problems in migration from tomcat 3.2.1 to tomcat 4.1.18.
I was initially having problems setting the context in server.xml and parser problems in web.xml but these seem to have disappeared.
I can run http://localhost:8080 and /examples
but not my context path /intranettv
My new problem is that when i try to view my servlet, it is returning a 404 error for the page
http:/localhost:8080/intranettv
It doesnt seem to be initialising the servlet.
Basically my server.xml points to new context here:
D:\intranettv\admin\public_site\ alias internettv
Here is my web.xml
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
<display-name>IntranetTV</display-name>
<description>
This is the IntranetTV application with a source code organization
based on the recommendations of the Application Developer's Guide.
</description>
<servlet>
<servlet-name>IntranetTV</servlet-name>
<servlet-class>com.bt.intranettv.view.IntranetTV</servlet-class>
<init-param>
<param-name>root</param-name>
<param-value>D:\intranettv\admin\public_site\</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>IntranetTV</servlet-name>
<url-pattern>/IntranetTV</url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>ManageContent</servlet-name>
<servlet-class>com.bt.intranettv.admin.ManageContent</servlet-class>
<init-param>
<param-name>root</param-name>
<param-value>D:\intranettv\admin\public_site\</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>ManageContent</servlet-name>
<url-pattern>/ManageContent</url-pattern>
</servlet-mapping>
</web-app>
Does anybody now what is happening.
(This is not a getout clause-but i compiled the java source with java 1.2 but tomcat is running under 1.4) Will this cause any errors? Some of somebodys java code doesnt compile with java 1.4 so i thought this would be a quick way out?
FROM THE CATALINA LOG FILE IM GETTING AN ERROR.
DOES ANYBODY KNOW WHATS CAUSING THIS ERROR LOG.

Context startup failed due to previous errors Which would be those parsing errors for web.xml

You say it works under TC 3x. This is almost inconceivable, because the DTD clearly states that <servlet> tags should all come before <servlet-mapping> tags, and you have them interspersed. If it did work under TC 3x, I can guarantee it will NOT work under TC 4x. You MUST have these tags in the right order.

Which is what I tried to hint at in your other post, and what someone else pointed out explicitly.

Reply. It doesnt seem to matter about where they are!.Definately works with tomcat 3.2.1 but I did change it anyway!
The problem I had which leads to a resource load up failure was actually in the server.xml file.
I had mistyped a <context> so the path was wrong.
Maybe we should put together a list of common errors so people can quickly pinpoint where they have gone wrong.
