first way with spring for android

[ahmeddrira]

Hi
i want to send an object "Tva" from my mobile to the data base
so i creat a Rest ws which i tested it with a Servlet on a web application , so it works

now i am traying to do the same think with android

i have writen this to code to retreive all tva from DB and insert one tva to the DB

 public String getAllTva()
	 {
		 List<MediaType> acceptableMediaTypes = new ArrayList<MediaType>();
	 acceptableMediaTypes.add(new MediaType("application","xml"));

	 HttpHeaders requestHeaders = new HttpHeaders();
	 requestHeaders.setAccept(acceptableMediaTypes);

	 HttpEntity<Tva> requestEntity = new HttpEntity<Tva>(requestHeaders);

	 String url = "http://192.168.1.65:8080/testRestWeb/REST/tva/findAll";

	 RestTemplate restTemplate = new RestTemplate();
	 ResponseEntity<Tva> responseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, Tva.class);
	 @SuppressWarnings("unchecked")
	List<Tva> listTva  = (List<Tva>) responseEntity.getBody();
	return listTva.get(1).toString();
	 		}

 public String ajouterTva()
	 {Tva tva = new Tva();
	 RestTemplate restTemplate = new RestTemplate();

	 tva.setLibTva("android");
	 tva.setTauxTva("spring");
	HttpHeaders requestHeaders = new HttpHeaders();
	 requestHeaders.setContentType(new MediaType("application","json"));
	 HttpEntity<Tva> requestEntity = new HttpEntity<Tva>(tva, requestHeaders);
	 try
	    {String url="http://192.168.1.65:8080/testRestWeb/REST/tva/save";
	    ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);//(url1,HttpMethod.POST,requestEntity, String.class);
	    return responseEntity.getBody();
	    }
	    catch(RestClientException rce)
	    {
	       
	    }
	
	return null;
	 }
}

is it correct : in the server side i have a class Tva wich is annotaded by @XmlRootElement and also on the client side i have the same class Tva , and my working service is :

@Path("/tva")
@Produces({ "application/xml", "application/json" })
public class TvaService {

	TvaSessionRemote tvaremote;

	public TvaService() {
		try {
			InitialContext ctx = new InitialContext();
			tvaremote = (TvaSessionRemote) ctx.lookup("tvaRemote");
		} catch (NamingException ne) {
			System.out.println("\n[MyRestService]NamingException: " + ne);
			ne.printStackTrace();
		}

	}

	@GET
	@Path("/findAll")
	@Produces({ "application/xml", "application/json" })
	public List<Tva> findAll() {

		return tvaremote.findAll();
	}

	@GET
	@Path("/findById")
	@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
	public Tva findById(@QueryParam("id") Integer id) {
		return tvaremote.findById(id);

	}

	@POST
	@Path("/save")
	@Consumes({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	// @Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
	// @Consumes("application/x-www-form-urlencoded")
	public void save(Tva tva) {
		tvaremote.save(tva);

	}

}
