i tryed to add css using relative path or c:url but no chance:

     <link rel="stylesheet" href="<c:url value = "bootstrap-rtl.min.css"/>" media="screen">

<link rel="stylesheet" href="assets/css/bootstrap-rtl.min.css" media="screen">

when i view page source and click on css url i see a 404 page. i guess i should do some config via Application or web.xml .but i dont know how

P.S: it is a restfull mvc app. so all routes are controlled through the controller class .
so (maybe) there is only access to paths that are defined in controller or defined in a config file. relative or absolute paths not work.

the picture shows the structure of the app: enter image description here

Static files don't need to be in the WEB-INF folder. We put JSP files in there to protect them from the public. The assets can go straight in the src/main/webapp folder. This is the root where the default servlet will serve the static files.

So let's say you have the following structure

src/main/webapp
           |
           +--- assets
           |      |
           +      +--- css
           |            |
           +            +--- styles.css
           |
           +--- WEB-INF
                  |
                  +--- jsp
                        |
                        +--- products.jsp

What you can use is the following link in you products.jsp page

<link rel="stylesheet" href="<c:url value="/assets/css/styles.css"/>" />

Since we are using c:url, it will add the base URL for us all the way to the context-path, wich would be http://localhost:8080/<app-name>/. Adding the path to the CSS page, we would have

http://localhost:8080/<app-name>/assets/css/styles.css

This is exactly what we want. When the browser makes the request for this page, the default servlet will serve it up from where we currently have it.
