Hi list
I have a question regarding the servlet-mapping property in web.xml. Normally a
url would look like this:
http://host:port/context/servlet-path
As many others I have tried to setup my servlet so that it matches the
following:
http://host:port/
I’m trying to obtain this by using the following url-mapping:
<servlet-mapping>
<servlet-name>ServletAdaptor</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
You'll need to deploy your application to the root context (i.e. as
ROOT.war) else you will always have a context path in the URL.
Maybe also read this for details :

I have read the answers on these two links:

It’s still not clear to me why this doesn’t work (using Tomcat 7.0)
You need to read section 12 of the servlet specification carefully.
I’ve have turned on Jersey tracing and this is what I get (on a url like this
http://localhost:8080/emner/81.20.00):
X-Jersey-Tracing-004:MATCH [ ---- / 1,00 ms | ---- %] Matching path [/]
What’s puzzling to me is that it seems that for some reason my path gets
stripped away before reaching the servlet. I would have expected something like
this instead:
X-Jersey-Tracing-004:MATCH [ ---- / 19,39 ms | ---- %] Matching path
[/emner/81.20.00]
At a guess, "/emner" is the context path.
Is it so in Tomcat, that when you use the url-pattern “/“ that the rest of path
is ignored when interpreting the original url?
No. "/" is the default servlet.
Is it different using other containers?
No.

Yes.
