I think it could be that the application is trying to get richfaces scripts in a wrong adress when i pass to localhost/monRep/faces/index.jsp.
I don't know if i have to change web.xml, and what to add or modify in it.
Now i'm pretty sure that the problem is the address:
when i go on http://localhost:8080/monRep/faces/a4j/s/3_3_3.Finalorg/richfaces/renderkit/html/css/basic_classes.xcss, i find the file basic_classes.xcss.
When i go on http://localhost/monRep/faces/a4j/s/3_3_3.Finalorg/richfaces/renderkit/html/css/basic_classes.xcss i don't find it.
I have for the moment no idea how to solve this.
