[tomcat7] host-manager/

Bonjour, tomcat m’indique une erreur 404 pour http://localhost:8080/host-manager/html
il manquerait quelquchose sous /var/www/html?

root@alpha30:/var/www/html# find / -name host-manager -print
/usr/share/tomcat7-admin/host-manager
find: ‘/run/user/1000/gvfs’: Permission non accordée
/var/cache/tomcat7/Catalina/localhost/host-manager
root@alpha30:/var/www/html# 
404 Not found

The page you tried to access (/host-manager/html.) does not exist.

The Host Manager application has been re-structured for Tomcat 7 onwards and some URLs have changed. All URLs used to access the Manager application should now start with one of the following options:

    /host-manager/html for the HTML GUI
    /host-manager/text for the text interface

Note that the URL for the text interface has changed from "/host-manager" to "/host-manager/text".

You probably need to adjust the URL you are using to access the Host Manager application. However, there is always a chance you have found a bug in the Host Manager application. If you are sure you have found a bug, and that the bug has not already been reported, please report it to the Apache Tomcat team. 

il manque un package?
