Don't top-post.  See item 6 under 
http://tomcat.apache.org/lists.html#tomcat-users

> I did map my servlet to the url-pattern "/".

The point we're trying to make is that you must not use a servlet mapping of 
"/" unless your servlet can handle the duties of DefaultServlet, including 
delivering static content such as CSS files and images.  Your mappings need to 
be more specific (as you appear to have already discovered, based on your first 
message).

Note that web browsers do not "find" the content inside the webapp directory; 
that's entirely up to the servlets of the webapp, including Tomcat's built-in 
DefaultServlet - if you haven't disabled it by mapping something else to "/".  
Correct your servlet mapping and things will work as desired.

Re: Tomcat can not locate the folders of CSS files inside a web app, if the url-pattern of a servlet is set to / inside web.xml

[Junqiang Zhang]

Thank all you guys very much for replying to my post.

I did map my servlet to the url-pattern "/". Is there any setting
could let web browsers find the static content inside the webapp
directory? If I put the static content into some other places, can web
browsers find the css file?

Does Jetty work the same way as Tomcat regarding this problem?

I have tried putting the webapp content in either ROOT directory or
mywebapp directory inside Tomcat/webapps. Web browsers could not find
the css file.

I copied the content of web.xml below.

Chuck,

That's precisely the point I was trying to make.

Clearly it does, as Violeta stated.  Since the webapp is overriding the mapping 
for "/", Tomcat's DefaultServlet will never get used, so there is _nothing_ 
available to deliver static content.

[Chris Gamache]

Junqiang Zhang has the expectation of the paths to the files correct.
/mywebapp/css/style.css is where that file should be located if exists in
the spot indicated in the tree diagram.

I don't think the default servlet plays in to this...

Can you post your web.xml ? I think perhaps one of your mappings is sitting
on "/*" which would keep tomcat from serving static resources.

Tomcat's "default" servlet [1] is mapped to "/".
The "default" servlet is a servlet that serves static resources as well as
serves the directory listings (if enabled).

You should know that when you map your servlet to "/" then you will
override the "default" servlet mapping.
So you should ensure that your servlet will do the same as "default" one in
order to serve the static resources.

When you map your servlet to "/someclass" then the static resources will be
served by "default" servlet as expected.

Violeta
