Tomcat deployment question

[Lakshmi Venkataraman]

I have upgraded from Tomcat 3.3 to Tomcat 5.5.23.  It is running on
WinXP and I am using Java 1.5.
 
Here's my dierctory set up:
 
${Catalina.Home}
     -- conf
           -- Catalina
                 --localhost
                        htdocs.xml 
     -- htdocs
           index.html
           --bin
           --html
           --jsp
           --css
           --jar
           --WEB-INF
                web.xml
                 --classes
                 --lib
                          
   
In server.xml, I modified the <Host> element to have {appBase="htdocs"
autoDeploy="false"}
I am using htdocs.xml in ${Catalina.home}/Catalina/localhost as the
context descriptor and is defined as follows:
 
 <Context docBase="${catalina.home}" override="true" privileged="true">
<Loader className="com.example.appClassLoader" reloadable="true"/> 
    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
     <!-- Uncomment this to disable session persistence across Tomcat
restarts -->
       <Manager pathname="" />
    </Context>
 
Tomcat is able to load appClassLoader. However, when I type,
http://localhost:8080, it is not able to load
the index.html found under the htdocs directory.   If I create ROOT
directory and move the index.html over there
it is able to load it.  
I guess, my main problem is how can I maintain the same direstory
structure as above without having to create ROOT 
and move everything below it?  The above directory structure worked in
Tomcat 3.3.
 
What am I missing? 
 
Thanks
