 <script src="<c:url value="WebContent/js/script.js" />"></script>
  <link href="/css/custom.css" rel="stylesheet" type="text/css" />

Answer 1

By using the url-pattern / you have overriden the container`s default servlet. This is the servlet which serves static content from the root of the web application. To keep your mapping you need to configure the Spring default servlet handler. How this works is that requests for static resources now comes through Spring instead of default servlet. Spring will now lookup the container defualt servlet based on container type. To achieve this add the line below to your application config file

<mvc:defualt-servlet-handler/>

Answer 2

In your controller accepts requests such as "/" because in your web.xml this way. Try changing this:

Example:

Web.XML:

<servlet-mapping>
    <servlet-name>library</servlet-name>
    <url-pattern>.*htm</url-pattern> 
  </servlet-mapping>
