Tomcat 8.0 - mime-mapping & content-type

Question

I recently searched for a problem that led me to the mime-mapping element defined in web-common_X_X.xsd and used in the web.xml file of web applications. My goal here is to configure Tomcat to include a specific Content-Type header when returning a response to a specific servlet.

I found previous entries mentioning functionality, but I can't get a trivial example for working with Tomcat 8.0.33.

For this test, I created the following servlet:

public class SimpleServlet extends HttpServlet {
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        IOUtils.write("Hello There!", resp.getOutputStream());
        resp.setStatus(202);
    }
}

And you have the following web.xml:

<web-app
        version="3.0"
        xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

  <servlet>
    <servlet-name>SimpleServlet</servlet-name>
    <servlet-class>com.jamf.swa.SimpleServlet</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>SimpleServlet</servlet-name>
    <url-pattern>*.swa</url-pattern>
  </servlet-mapping>

  <mime-mapping>
    <extension>swa</extension>
    <mime-type>text/rtf;charset=UTF-8</mime-type>
  </mime-mapping>

</web-app>

I tried to run this test with and without encoding included in the mime-type element. The type "text / rtf" is also arbitrary. I tested others.

Once the application is running, I make the following request /testing.swa:

curl --trace-ascii - http://localhost:8080/testing.swa

== Info: TCP_NODELAY set
== Info: Connected to localhost (::1) port 8080 (#0)
