I want to use javax.ws.rs.core.Response to send and receive an Card entity object. But I don't know how to convert the contents back in to a Card object.
My testCreate() method should execute the create(Card card) method, receive back the json and convert it in to a card object. But I somehow always get type mismatches or it says that the getEntity() method can't be executed like this: response.getEntity(Card.class).
Does anybody know how I have to handle the response correctly so that I can convert the returned json entity in to a Card object again?
Here my CardResource method:
#POST
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response create(Card card) {
Card c = dao.create(card);
if(c.equals(null)) {
return Response.status(Status.BAD_REQUEST).entity("Create failed!").build();
}
return Response.status(Status.OK)
.entity(c)
.type(MediaType.APPLICATION_JSON)
.build();
}
And here my CardResourceTests class
#Test
public void testCreate() {
boolean thrown = false;
CardResource resource = new CardResource();
Card c = new Card(1, "Cardname", "12345678", 1, 1,
"cardname.jpg", new Date(), new Date());
try {
Response result = resource.create(c);
System.out.println(result.getEntity(Card.class)); // not working!!!
if(result.getStatus() != 200) {
thrown = true;
}
} catch(Exception e) {
e.printStackTrace();
thrown = true;
}
assertEquals("Result", false, thrown);
}
And here my Card.class
#XmlRootElement
#PersistenceCapable(detachable="true")
public class Card {

PersistenceManager pm = PMF.get().getPersistenceManager();
Card c = new Card(card.getId(), card.getName(), card.getCode(),
card.getCardProviderId(), card.getCodeTypeId(), card.getPicturePath(),

try {
pm.makePersistent(c);
} catch(Exception e) {
logger.severe("Create failed: " + e.getMessage());
return null;
} finally {
pm.close();
}
return c;
}
}
Is your Card class using #XmlRootElement and #XmlElement annotations to enable JAXB mapping JSON to/from POJO?
See example:
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Book {
#XmlElement(name = "id")
String id;
//...
I am not sure that it is correct to call the annotated web-service method just like a simple method with params. Try to remove all annotations from your CardResource class and invoke this method simply like a class method.

and im trying to getID and use that in another call. This is an object that I am trying to turn into an integer an then use that in a seperate call again.
referralResponseResponse = call1.getReferral(token).execute();
int i = (int) referralResponseResponse.body().getId();
System.out.println("Int: " + i);
I should also note the json that I'm using this data from is very large so ive just used jsonpogo to extract this information to a java file and then use the parts that apply to me, I dont imagine i have to set up a java class for every part of the retruned json
Try to add following annotation for your POJO class:
#JsonIgnoreProperties(ignoreUnknown = true)
How get value in array "rate" to invoke getters methods ?
My Json response is something as below and confused how to parse it using GSON. Please have look on the following and guide me how i can parse it using GSON.

"Time":"10:35am",
"Ask":"973.16",
"Bid":"973.10"

I use classes to parse apart

#SerializedName("rate")
private List<Rate> rate = null;
public List<Rate> getRate() {
return rate;
}
public void setRate(List<Rate> rate) {

}
}
Trying to get the values
Main.java
public class Main {
/* ..... */
Gson gson = new Gson();
Market market = gson.fromJson(json, Market.class);
//error: incompatible types: Rate cannot be converted to List<Rate>
for( List<Rate> res : market.getQuery().getResults().getRate());
{
Log.v(LOG_TAG, res); // error: cannot find symbol variable res
}
}
how to do it properly ?
The syntax of your for each loop is incorrect. Since you are attempting to loop through a list of Rate objects, the type of res should be a Rate, not a list of Rates:
for (Rate res : market.getQuery().getResults().getRate()) {
// code here
}
As an aside, you should consider checking for null values before dereferencing all of those child objects as you run the risk of throwing a NullPointerException at runtime.
I want to order the data descending in hibernate,

List<MPNValas> mpnvalasList = getHibernateTemplate().findByCriteria(criteria);

this is my controller,
#RequestMapping("/admin/mpn-valas.html")
public ModelAndView listMPNValas(ModelMap model)throws Exception
{
User user = (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String sessionUser = user.getUsername();
try{

mav.addObject("mpnvalas", mpnvalas);

and this the list of data

any help will be pleasure :))
You miss nothing, just note that the argument to the desc method is case sensitive and should match the name of the attribute to sort by.
Criteria criteria = session.createCriteria(Foo.class, "FOO");
criteria.addOrder(Order.desc("id"));
