thank you for your answer. Unfortunately I don't understand how I can define a tomcat specific path by using watched repository and so access them through http request...
AFAIK css, js and other web static files can't be pushed into virgo repository as they are not virgo artifact (which are configuration (properties file), PAR, plan, and library only).
So I guess my initial question was unclear. Let me precise it. I've a WAR with JS, CSS and other web static files in the WEB-INF dir I want to externalize from this WAR in order to edit and then refresh my app without recompiling my WAR and redeploy it into Virgo to get the changes... For this case Tomcat context docBase is a good solution (http://www.moreofless.co.uk/static-content-web-pages-images-tomcat-outside-war/) but unfortunately it's not supported by Virgo currently.
So I'd like to know :
+ what are the blocking points to support this tomcat feature in Virgo (maybe can I implement a prototype feature on Virgo if you give me some inputs)
+ is there an alternative to externalize this kind of web static files and push some context path in tomcat with Virgo ?
