Web.xml: Are url template tags relative to each other?

Question

   <servlet-mapping>
      <servlet-name>myName</servlet-name>
      <url-pattern>/aName</url-pattern>
   </servlet-mapping>

    <security-constraint>

            <web-resource-collection>

                    ...

                    <url-pattern>
                            /*
                    </url-pattern>

            </web-resource-collection>

             ...

    </security-constraint>
