Re: [jetty-users] Override default servlet mapping in Jetty8 with Servle

[Jan Bartel <janb@xxxxxxxxxxx>]

Edgar,

You can't "override" a servlet that already has a mapping with the new
servlet 3 api. Quoting from
http://docs.oracle.com/javaee/6/api/javax/servlet/ServletRegistration.html
:

   "If any of the specified URL patterns are already mapped to a
different Servlet, no updates will be performed."

 In this case, the default servlet, mapped at "/" is configured in
webdefault.xml. If you wish to replace it, you can provide your own
webdefault.xml that has it removed.

However, be very careful replacing the default servlet unless you
understand how the mapping works - the default servlet used to serve
static content is mapped to "/" and is only invoked if every other
mapping cannot be matched against a given url.
