Hi,
The problem with your assumption about the servlet path is in fact a
problem with your servlet registration with Jetty.
In the web.xml you have the following servlet mapping:
<servlet-mapping>
<servlet-name>HelloWorldExample</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
According to the Spec (e.g. Servlet API 2.3, SRV.11.2, Specification of
Mappings): "A string containing only the '/' character implies the
"default" servlet of the application. In this case the servlet path is
the request URI minus the context path and the path info is null."
I would assume, that if you would register the servlet with "/*" (notice
the trailing asterisk) you might see the same result in Jetty as you see
in Felix and Equinox.
HTH
Regards
Felix
