Hi, I posted an answer her link I'm aware that if this configuration file is wrong every tomcat host instance (every single Tomcat user) will fail, and their website will not be available untill the server.xml is fixed. But, each user should be able to configure at least his host to improve functionalities and performances : -Pure Tomcat SSL configuration -War root path url -connection pool ... So you cannot let anyone edit this file manually, you can't edit it each time an user need it, and we need to configure it when we need it... So as a request I created my own thread, is this possible to create a link in the panel with a simple form. This form will send xml lines, and the server will put those line in the user host inside the server.xml ? I know you have a lot of things to do, that's why I may be able to help you and send you my work if you can tell me in wich language I need to dev that. We really need this Thank you
