Hello,
I encounter problem of performance in the serialization of an object by
restlet-gwt : the json version takes 24ms whereas the gwt version takes 18s ...
ON THE CLIENT SIDE :
// JSON Button :
requestButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
ClientResource r = new
ClientResource("/restlet/operations/byAccDate/start01102010/end10102010");
r.setOnResponse(new Uniform() {
public void handle(Request request, Response response) {
try {
respAreaLabel.setText(response.getEntity().getText());
} catch (IOException e) {
e.printStackTrace();
}
}
});
r.get(MediaType.APPLICATION_JSON);
}
});
// GWT Button :
btReqAllOpe.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
OperationsProxy orp = GWT.create(OperationsProxy.class);
orp.getClientResource().setReference("/restlet/operations/byAccDate/start01102010/end10102010");
orp.getClientResource().getClientInfo().getAcceptedMediaTypes().add(new
Preference<MediaType>(MediaType.APPLICATION_JAVA_OBJECT_GWT));
orp.retrieve(new Result< Operations >() {
public void onFailure(Throwable caught) {
String st = "error:" + caught.getMessage();
respAreaLabel.setText(st);
}
@Override
public void onSuccess(Operations opeList) {
for (Operation ope : opeList) {
addRowOpe(ft , ope);
}
}
});
}
});
ON THE SERVER SIDE :
public class CopyOfOperationsServerRessource extends ServerResource
implements OperationsServerRessource_Int {
private OperationDaoInterface opeDao;
public void setOpeDao(OperationDaoInterface opeDao) {
this.opeDao = opeDao;
}
public OperationDaoInterface getOpeDao() {
return opeDao;
}
@Get
public Operations retrieve() {
ArrayList<Operation> result = new Operations(opeDao.getAll()) ;
return new Operations(result) ;
}
@Get("json")
public JsonRepresentation retrieveJson() {
ArrayList<Operation> result = new Operations(opeDao.getAll()) ;
XStream xstream = new XStream(new JsonHierarchicalStreamDriver());
xstream.setMode(XStream.NO_REFERENCES);
xstream.alias("operation", Operation.class);
return new JsonRepresentation( xstream.toXML(result) );
}
}
public interface OperationsProxy extends ClientProxy {
@Get
public void retrieve(Result<Operations> callback);
}
I thought I correctly use the gwt plugin, but the performance gap with the json
version seems just too huge : I must have missed something : any idea ?
regards !
Ben
