basic REST service for my xpage application

I want to set up some basic REST services for my XPage application. So I added the xe:restService control on an xpage and choose the xe:customRestService where I refer to a Java class:

<xe:restService id="restService1" pathInfo="json" state="false"><xe:this.service><xe:customRestService contentType="application/json"                serviceBean="se.banking.desk.CustomSearchHelper"></xe:customRestService></xe:this.service></xe:restService>

The CustomSearchHelper class it self is still pretty empty but I am wondering if I am on the right track?

Here is the code for the class:

package se.banking.desk;import java.io.IOException;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.ibm.domino.services.ServiceException;import com.ibm.domino.services.rest.RestServiceEngine;import com.ibm.xsp.extlib.component.rest.CustomService;import com.ibm.xsp.extlib.component.rest.CustomServiceBean;public class CustomSearchHelper extends CustomServiceBean {    @Override    public void renderService(CustomService service, RestServiceEngine engine) throws ServiceException {        HttpServletRequest request = engine.getHttpRequest();                   String method = request.getMethod();        HttpServletResponse response = engine.getHttpResponse();                response.setHeader("Content-Type", "text/javascript; charset=UTF-8");                if(method.equals("GET")){            this.get(engine);        }        else if(method.equals("POST")){            this.post(engine,request);        }        else{            this.other(engine);        }    }    public void get(RestServiceEngine engine){        HttpServletResponse response = engine.getHttpResponse();        try {            response.getWriter().write("get()");            response.getWriter().close();            return;        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }    public void post(RestServiceEngine engine,HttpServletRequest request){      HttpServletResponse response = engine.getHttpResponse();      Map parameters = request.getParameterMap();      try {          response.getWriter().write("post()");          response.getWriter().write( request.getParameter("form"));          String[] form = (String[])parameters.get("form");          String val = form[0];          response.getWriter().write(val);        response.getWriter().close();    } catch (Exception e) {        // TODO: handle exception    }       }    public void other(RestServiceEngine engine){       HttpServletResponse response = engine.getHttpResponse();        try {            response.getWriter().write("other()");            response.getWriter().close();            return;        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}

Questions I have: Is this a good way to write a custom REST service? Are there alternatives? Where can I find more examples/information that start at the starter level?
