Facelet include of a servlet generated content
===

I'd like to include a servlet generated content in a facelet using ui:include. So far I only got errors.

Note that the servlet works fine, GET requests from a browser are ok.

Note that I can successfully include content from another facelet file, but not when the content is servlet generated.

I googled and stackoverflowed my issue but could not find matching responses.

myfacelet.xhtml (at the root of the webapp, i.e. reached by "http://localhost:8080/mywebapp/myfacelet.xhtml"):

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <h:head>
      <title>JSF Dynamic Content</title>
    </h:head><h:body>
      <h3>Dynamic content:</h3>
      <ui:include src="dynamic-content"/>
    </h:body>
    </html>

MyServlet.java (can be reached by "http://localhost:8080/mywebapp/dynamic-content"):

    @WebServlet(name = "DynamicContentServlet", urlPatterns = {"/dynamic-content"})
    public class DynamicContentServlet extends HttpServlet {
      @Override
      public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter writer = response.getWriter();
        writer.println("<p>Dynamic stuff</p>");
      }
    }

web.xml (JSF related stuff only) :

    <context-param>
      <param-name>javax.faces.PROJECT_STAGE</param-name>
      <param-value>Development</param-value>
    </context-param>
    <servlet>
      <servlet-name>FacesServlet</servlet-name>
      <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    </servlet>
    <servlet-mapping>
      <servlet-name>FacesServlet</servlet-name>
      <url-pattern>/faces/*</url-pattern>
      <url-pattern>*.jsf</url-pattern>
      <url-pattern>*.faces</url-pattern>
      <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>

For ui:include="/dynamic-content" and urlPatterns="/dynamic-content"
or ui:include="/mywebapp/dynamic-content" and urlPatterns="/dynamic-content"
the error is:

What is wrong with my code?

Is the include possible?

How can I achieve it?

Best regards
