Tomcat virtual host and struts

i buy a tomcat virtual host config like this:
<Host name="www.xxx.com" debug="0" autoDeploy="false" appBase="/home/xxx/web">
<Context path="" docBase="" debug="0"/>
<Alias>xxx.com</Alias>
</Host>
The web master has disabled the tomcat manager
so if i want to use the manager shall i change
it to
<Context path="/manager" debug="0" privileged="true" docBase="/path-to/server/webapps/manager"/>
it that ok ?
i then upload struts-blank (unpacked) ,but i
cann't load the Welcome.do it says
The requested URL /Welcome.do was not found on this server.
i do nothing with all the code in struts-blank directory ! what is the problem ?

BTW:
i am sure that struts can find struts-config.xml
so it has nothing to do with the path of the struts-config.xml i think maybe the ActionServlet has not been load. what config in tomcat can prevent ActionServlet being loaded ???

sloved!
