> There are three possible ways to configure a Restlet application within a servlet container (http://www.restlet.org/documentation/2.0/jee/ext/org/restlet/ext/servlet/ServerServlet.html) and using the subclassed SpringServerServlet enables configuration within Camel by injecting the Restlet Component - however this is currently only available internally within the Camel component.
> Use of the Restlet servlet within a servlet container enables routes to be configured with relative paths in URIs (removing the restrictions of hard-coded absolute URIs) and for the hosting servlet container to handle incoming requests (rather than have to spawn a separate server process on a new port).
> To configure, add the following to your camel-context.xml;
>   <camelContext>
>     <route id="RS_RestletDemo">
>       <from uri="restlet:/demo/{id}" />
>       <transform>
>         <simple>Request type : ${header.CamelHttpMethod} and ID : ${header.id}</simple>
>       </transform>
>     </route> 
>   </camelContext>
>   <bean id="RestletComponent" class="org.restlet.Component" />
>   <bean id="RestletComponentService" class="org.apache.camel.component.restlet.RestletComponent">
>     <constructor-arg index="0">
>       <ref bean="RestletComponent" />
>     </constructor-arg>
>   </bean>
> And add this to your web.xml;
>   <!-- Restlet Servlet -->
>   <servlet>
>     <servlet-name>RestletServlet</servlet-name>
>     <servlet-class>org.restlet.ext.spring.SpringServerServlet</servlet-class>
>     <init-param>
>       <param-name>org.restlet.component</param-name>
>       <param-value>RestletComponent</param-value>
>     </init-param>
>   </servlet>
>   <servlet-mapping>
>     <servlet-name>RestletServlet</servlet-name>
>     <url-pattern>/rs/*</url-pattern>
>   </servlet-mapping>
> You will then be able to access the deployed route at http://localhost:8080/mywebapp/rs/demo/1234 where;
>  - localhost:8080 is the server and port of your servlet container
>  - mywebapp is the name of your deployed webapp
> Your browser will then show the following content;
> "Request type : GET and ID : 1234"
