Generic DAO search with group by / unqiue

I am using hibernate-generic-dao for a searching function. Since I only need to show one of the records if they have same value on a column field. But I am not sure how to achieve this by the search / filter functions.
package com.googlecode.genericdao.search;
PersonContact domain object:
...
#Column(name = "group_key", length = 20)
public String getGroupKey() {
return groupKey;
}
#Formula(value = "(SELECT status from person_contact m " +
" WHERE m.case = case AND m.movement_id = movement_id )")
public String getActiveRecord() {
return activeRecord;
}
...
Search search = new Search();
search.addFilterNotNull("groupKey"); //groupKey is the field I want to use "group by / unqiue" with it
search.addFilterEqual("type","C");
search.addFilterCustom("{activeRecord} != 'I' ");
search.setMaxResults(limit);//for paging
search.setFirstResult(startIdx);
SearchResult<PersonContact> resultObj = PersonContactDAO.searchAndCount(search);

You should probably ask this question by opening an issue in the repository for that project here: https://github.com/vincentruan/hibernate-generic-dao
It seems though as if the project is abandoned, so unless you feel like digging into the details, you should probably try to get away from it.

TFS JAVA SDK - How to run shared query

I have a application which useds TFS JAVA SDK 14.0.3 .
I have a shared query  on my tfs , how can i run the shared query and get the response back using TFS SDK 14.0.3
Also I could see that the query url will expire in every 90 days , so any better way to execute the shared query?
Now I  have a method to run a query , i want method  to  run shared query also.
public void getWorkItem(TFSTeamProjectCollection tpc, Project project){
WorkItemClient workItemClient = project.getWorkItemClient();
// Define the WIQL query.
String wiqlQuery = "Select ID, Title,Assigned from WorkItems where (State = 'Active') order by Title";
// Run the query and get the results.
WorkItemCollection workItems = workItemClient.query(wiqlQuery);
System.out.println("Found " + workItems.size() + " work items.");
System.out.println();
// Write out the heading.
System.out.println("ID\tTitle");
// Output the first 20 results of the query, allowing the TFS SDK to
// page
// in data as required
final int maxToPrint = 5;
for (int i = 0; i < workItems.size(); i++) {
if (i >= maxToPrint) {
System.out.println("[...]");
break;
}
WorkItem workItem = workItems.getWorkItem(i);
System.out.println(workItem.getID() + "\t" + workItem.getTitle());
}
}

Shared query is a query which has been run and saved, so what you need should be getting a a shared query, not run a shared query. You could refer to case Access TFS Team Query from Client Object API:
///Handles nested query folders
private static Guid FindQuery(QueryFolder folder, string queryName)
{
foreach (var item in folder)
{
if (item.Name.Equals(queryName, StringComparison.InvariantCultureIgnoreCase))
{
return item.Id;
}
var itemFolder = item as QueryFolder;
if (itemFolder != null)
{
var result = FindQuery(itemFolder, queryName);
if (!result.Equals(Guid.Empty))
{
return result;
}
}
}
return Guid.Empty;
}
static void Main(string[] args)
{
var collectionUri = new Uri("http://TFS/tfs/DefaultCollection");
var server = new TfsTeamProjectCollection(collectionUri);
var workItemStore = server.GetService<WorkItemStore>();
var teamProject = workItemStore.Projects["TeamProjectName"];
var x = teamProject.QueryHierarchy;
var queryId = FindQuery(x, "QueryNameHere");
var queryDefinition = workItemStore.GetQueryDefinition(queryId);
var variables = new Dictionary<string, string>() {{"project", "TeamProjectName"}};
var result = workItemStore.Query(queryDefinition.QueryText,variables);
}
By the way, you could also check the REST API in the following link:

Setting Parameters through url javaplay

so as part of some work I've been doing I was given a file with WebServices that are being used in a Swift application. I have zero familiarity with WebServices and only know Java through syntax understanding. I need to call one of these gets with a parameter from the swift application. What I'm trying to figure out first and foremost is how I can call one of these webservices with a parameter from the URL it's associated with. For example down below I want to call the method
http://localhost:9000/ListVehicleByPlateNumber
and I want to specify the parameter through the URL say something like
http://localhost:9000/ListVehicleByPlateNumber?para="123"
But this doesn't assign any value to the parameter and I'm not getting results. If I hardcode so that the string used in the function is = "123" it gives me the results I'm looking for. I just need to know how I can pass this parameter through the url, syntax-wise.
Routes file
GET /ListVehicleByPlateNumber controllers.NewVehicle.listVehicleByPlateNumber(para: String ?="")
Controller
public Result listVehicleByPlateNumber(String para){
NewVehicleModel v = new NewVehicleModel();
List<NewVehicleModel> vehiclesC = v.searchByPlateVehicle(para);
ObjectNode wrapper = Json.newObject();
ObjectNode msg = Json.newObject();
if(vehiclesC != null) {
msg.set("VehicleList", toJson(vehiclesC));
wrapper.set("success", msg);
return ok(wrapper);
}else{
msg.put("error", "There are no vehicles with the plate number");
wrapper.set("error", msg);
return badRequest(wrapper);
}
}
Where it's called
public List<NewVehicleModel> searchByPlateVehicle(String plateNumber){
Transaction t = Ebean.beginTransaction();
List<NewVehicleModel> vehicles = new ArrayList<>();
try {
String sql = "SELECT V.idNewVehicle, V.VehicleType,V.PlateNumber,V.VehicleJurisdiction,V.State,V.Vin,V.Year, " +
"V.Make,V.modelos,V.RegistrationNumber,V.InsuranceCompany,V.PurchaseDate,V.ExpirationDate,V.idPersonaFK " +
"FROM NewVehicle V " +
"WHERE V.PlateNumber = :plateNumber";
RawSql rawSql = RawSqlBuilder.parse(sql)
.columnMapping("V.idNewVehicle", "idNewVehicle")
.columnMapping("V.State", "state")
.columnMapping("V.VehicleType", "vehicleType")
.columnMapping("V.PlateNumber", "plateNumber")
.columnMapping("V.VehicleJurisdiction", "vehicleJurisdiction")
.columnMapping("V.Vin", "vin")
.columnMapping("V.Year", "year")
.columnMapping("V.Make", "make")
.columnMapping("V.modelos", "modelos")
.columnMapping("V.RegistrationNumber", "registrationNumber")
.columnMapping("V.InsuranceCompany", "insuranceCompany")
.columnMapping("V.PurchaseDate", "purchaseDate")
.columnMapping("V.ExpirationDate", "expirationDate")
.columnMapping("V.idPersonaFK", "idPersonaFK")
.create();
Query<NewVehicleModel> query = Ebean.find(NewVehicleModel.class);
query.setRawSql(rawSql)
.setParameter("plateNumber", plateNumber);
vehicles = query.findList();
t.commit();
}
catch (Exception e){
System.out.println(e.getMessage());
}finally {
t.end();
}
return vehicles;
}

Found my own answer. I ended up casting from Integer to String here's how it looks in routes
GET /ListVehicleByPlateNumber/:para controllers.NewVehicle.listVehicleByPlateNumber(para: Integer )
Controller
public Result listVehicleByPlateNumber(int para){
String p = String.valueOf(para);
URI Format for value 123 example.
http://localhost:9000/ListVehicleByPlateNumber/123

How do I extract properties from Entities in Google App Engine Datastore using Java

I am using Google App Engine and trying to query / pull data from the Datastores. I have followed nearly 20 different tutorials without any luck.
Here is a picture of my Datastore and the respective sample data I have stored in there:
Here is some of the code I have to pull the data:
//To obtain the keys
final DatastoreService dss=DatastoreServiceFactory.getDatastoreService();
final Query query=new Query("Coupon");
List<Key> keys = new ArrayList<Key>();
//Put the keys into a list for iteration
for (final Entity entity : dss.prepare(query).asIterable(FetchOptions.Builder.withLimit(100000))) {
keys.add(entity.getKey());
}
try {
for (int i = 0; i < keys.size(); i++){
Entity myEntity = new Entity("Coupon", keys.get(i));
System.out.println("Size of the Keys array = " + keys.size());
String description = (String) myEntity.getProperty("desc");
String endDate = (String) myEntity.getProperty("endDate");
System.out.println("Description = " + description);
System.out.println("End Date: " + endDate);
//Map here is empty...
Map<String, Object> test = myEntity.getProperties();
System.out.println("MAP SIZE = " + test.size());
}
} catch (Exception e){
e.printStackTrace();
}
**OUPUT:**
Size of the Keys array = 2
Description = null
End date = null
MAP SIZE = 0
I have no clue why the description and end date are null. It is clearly pulling in the right Entity as the size shows 2, which matches the picture shown. Also, when I print the keys out, it matches as well
(Something like this: for the keys.get(i).toString(); -- Entity [!global:Coupon(123)/Coupon(no-id-yet)]:
. Or: Key String = !global:Coupon(5730827476402176)
I have followed the documentation (here) and some examples (here) to the best of my ability but I cannot seem to figure it out. Does anyone have any recommendations or experience in how to obtain the properties from Entities once you have them without them returning null?
I have gone through the following Stackoverflow questions without any success so please do not close this with a simple duplicate question marker on it:
1) How do i get all child entities in Google App Engine (Low-level API)
2) Storing hierarchical data in Google App Engine Datastore?
3) How do you use list properties in Google App Engine datastore in Java?
4) Mass updates in Google App Engine Datastore
5) Checking if Entity exists in google app engine datastore. .

have you tried this?
//Put the keys into a list for iteration
for (final Entity entity : dss.prepare(query).asIterable (FetchOptions.Builder.withLimit(100000))) {
String description = (String) entity.getProperty("desc");
String endDate = (String) entity.getProperty("endDate");
System.out.println("Description = " + description);
System.out.println("End Date: " + endDate);
}
In your example, you creating entity and it is expected that properties will be empty

Eureka! Many thanks to all that answered. Patrice and user2649908 especially thank you as you led me to the answer.
So, Patrice was entirely correct in that I was querying to get the keys, building a new entity, and then trying to parse the newly created (empty) entity.
The solution was to utilize PersistenceManager to parse the data and then use getter/ accessor methods to do so. The link for persistence manager (which I more or less just copied directly from as it worked perfectly) is here:
How to use JDO persistence manager?
Once I setup the persistence manager, I was able to get it to pull the data using this code:
try {
for (int i = 0; i < keys.size(); i++){
//See the link for How to use JDO persistence manager on how to use this
PersistenceManager pm = MyPersistenceManagerClass.getPM();
//Need to cast it here because it returns an object
Coupon coupon = (Coupon) pm.getObjectById(Coupon.class, keys.get(i));
System.out.println("Created by = " + coupon.getCreatedBy());
System.out.println("Description = " + coupon.getDesc());
System.out.println("Modified by = " + coupon.getModifiedBy());
}
} catch (Exception e){
e.printStackTrace();
}

How to find the list of user stories under a given iteration and a given project using rally rest api

I am able to get the iterations under the project object. Now how do I get the iteration I need under that project and then drill down to the stories in that iteration using the JAVA toolkit?
https://sandbox.rallydev.com/slm/webservice/v2.0/project/7191194697/iterations

Given a project:
String projectRef = "/project/1234";
You may scope your requests as follows:
iterationRequest.setProject(projectRef);
or
storyRequest.setProject(projectRef);
If you scoped a story request to a project, then you may query on stories by traversing Iteration.Name if you know the iteration already:
storyRequest.setQueryFilter(new QueryFilter("Iteration.Name", "=", "my Iteration 1"));
Here is a more complex example that returns stories assigned to iterations that fall within the timbox of a specific release. If, for example, you have 4 iterations per release, this code will return stories assigned to all four iterations.
If you code against the sandbox, replace the value in the host variable accordingly.
public class FindIterationsByReleaseDateAndStories {
public static void main(String[] args) throws URISyntaxException, IOException {
String host = "https://rally1.rallydev.com";
String username = "user#co.com";
String password = "secret";
String projectRef = "/project/12352608219";
String applicationName = "Find Iterations by Release Dates and Stories";
RallyRestApi restApi = null;
try {
restApi = new RallyRestApi(
new URI(host),
username,
password);
restApi.setApplicationName(applicationName);
System.out.println(restApi.getWsapiVersion());
QueryRequest releaseRequest = new QueryRequest("Release");
releaseRequest.setFetch(new Fetch("ReleaseStartDate", "ReleaseDate"));
releaseRequest.setScopedDown(false);
releaseRequest.setScopedUp(false);
releaseRequest.setProject(projectRef);
releaseRequest.setQueryFilter(new QueryFilter("Name", "=", "r1"));
QueryResponse releaseQueryResponse = restApi.query(releaseRequest);
int numberOfReleasesInProject = releaseQueryResponse.getTotalResultCount();
System.out.println(numberOfReleasesInProject);
JsonObject releaseJsonObject = releaseQueryResponse.getResults().get(0).getAsJsonObject();
System.out.println(releaseJsonObject.get("ReleaseStartDate"));
System.out.println(releaseJsonObject.get("ReleaseDate"));
String rsd = releaseJsonObject.get("ReleaseStartDate").getAsString();
String rd = releaseJsonObject.get("ReleaseDate").getAsString();
QueryRequest iterationRequest = new QueryRequest("Iteration");
iterationRequest.setFetch(new Fetch("Name","StartDate","EndDate"));
iterationRequest.setScopedDown(false);
iterationRequest.setScopedUp(false);
iterationRequest.setProject(projectRef);
iterationRequest.setQueryFilter(new QueryFilter("StartDate", ">=", rsd).and(new QueryFilter("EndDate", "<=", rd)));
QueryResponse iterationQueryResponse = restApi.query(iterationRequest);
int numberOfIteraitons = iterationQueryResponse.getTotalResultCount();
System.out.println("numberOfIteraitons " + numberOfIteraitons);
if(numberOfIteraitons >0){
for (int i=0;i<numberOfIteraitons;i++){
JsonObject iterationJsonObject = iterationQueryResponse.getResults().get(i).getAsJsonObject();
String iterationName = iterationJsonObject.get("Name").getAsString();
System.out.println("iteration: " + iterationName);
QueryRequest storyRequest = new QueryRequest("HierarchicalRequirement");
storyRequest.setProject(projectRef);
storyRequest.setFetch(new Fetch(new String[] {"Name", "FormattedID","ScheduleState"}));
storyRequest.setLimit(1000);
storyRequest.setScopedDown(false);
storyRequest.setScopedUp(false);
storyRequest.setQueryFilter(new QueryFilter("Iteration.Name", "=", iterationName));
QueryResponse storyQueryResponse = restApi.query(storyRequest);
System.out.println("Number of stories in " + iterationName + " :" + storyQueryResponse.getTotalResultCount());
for (int j=0; j<storyQueryResponse.getResults().size();j++){
JsonObject storyJsonObject = storyQueryResponse.getResults().get(j).getAsJsonObject();
System.out.println("Name: " + storyJsonObject.get("Name") + " FormattedID: " + storyJsonObject.get("FormattedID") + " ScheduleState: " + storyJsonObject.get("ScheduleState"));
}
}
}
}
finally{
if (restApi != null) {
restApi.close();
}
}
}
}
UPDATE: as far as your question in the comment, the code above is equivalent of
https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?query=((Iteration.Name = i1) AND (Project = /project/12352608219))
There are other ways to achive the same result. Iteration name may not be unique, hence the second condition by project ref. In the code the request's project is set first, that's why the query itself uses one condition, but effectively there are two. If you know your iteration's ref, or ObjectID then the same result will be returned from (Iteration = /iteration/123456789), and there is no need to filter by project since a reference or ObjectID are unique.
WS API doc is interactive.Test your queries in WS API and copy the resulting query URLs from the address bar if you want to see how queries are formed:
-Query in the context of the intended object: click on the work item type in the Object Model, e.g. Defect or HierarchicalRequirement before typing your query in the query box.
-Enter a query in a box, e.g (Iteration.Name = i1)
-Click on Query button
-Results are displayed in the window from which you can copy query URL from address bar of your browser.
