How to get the suggested terms from Solr suggester response [duplicate]

What is the correct way of getting results from solrj using Solr Suggester?
This is my request:
SolrQuery query = new SolrQuery();
query.setRequestHandler("/suggest");
query.setParam("suggest", "true");
query.setParam("suggest.build", "true");
query.setParam("suggest.dictionary", "mySuggester");
query.setParam("suggest.q", "So");
QueryResponse response = server.query(query);
However I found it extremely difficult to get the response. The way I got the response is with this:
NamedList obj = (NamedList)((Map)response.getResponse().get("suggest")).get("mySuggester");
SimpleOrderedMap obj2 = (SimpleOrderedMap) obj.get("So");
List<SimpleOrderedMap> obj3 = (List<SimpleOrderedMap>) obj2.get("suggestions");
This seems to assume a lot about the objects I am getting from the response and will be difficult to anticipate errors.
Is there a better and cleaner way than this?

In new versions have a SuggesterResponse:
https://lucene.apache.org/solr/5_3_1/solr-solrj/org/apache/solr/client/solrj/response/SuggesterResponse.html

Best option is to get it as List, below code worked for me
HttpSolrClient solrClient = new HttpSolrClient(solrURL);
SolrQuery query = new SolrQuery();
query.setRequestHandler("/suggest");
query.setParam("suggest.q", "Ins");
query.setParam("wt", "json");
try {
QueryResponse response = solrClient.query(query);
System.out.println(response.getSuggesterResponse().getSuggestedTerms());
List<String> types=response.getSuggesterResponse().getSuggestedTerms().get("infixSuggester");
System.out.println(types);
} catch (SolrServerException | IOException e) {
e.printStackTrace();
}

You can get the suggestions via the SpellCheckResponse by doing the following
SpellCheckResponse spellCheckResponse=response.getSpellCheckResponse();

How to execute searchAndRank method in IBM Watson Retrieve And Rank API through Java wrapper

I am trying to perform a retrieveAndRank query using Java wrapper. I follow the online javadocs for Retrieve and Rank API.
The example there for SearchAndRank is:
https://www.ibm.com/watson/developercloud/retrieve-and-rank/api/v1/#query_ranker
RetrieveAndRank service = new RetrieveAndRank();
service.setUsernameAndPassword("{username}","{password}");
HttpSolrClient solrClient = new HttpSolrClient;
solrClient = getSolrClient(service.getSolrUrl("scfaaf8903_02c1_4297_84c6_76b79537d849"), "{username}","{password}");
SolrQuery query = new SolrQuery("what is the basic mechanism of the transonic aileron buzz");
QueryResponse response = solrClient.query("example_collection", query);
Ranking ranking = service.rank("B2E325-rank-67", response);
System.out.println(ranking);
but RetrieveAndRank class has no such rank(String rankerId, QueryResponse response) method. Just one getting a file or an InputStream as arguments (browsing IBM’s source code I see it expects CSV content not a java QueryResponse there).
How should I pass QueryResponse to the rank method?
I am using solr-solrj-5.5.2.jar and java-sdk-3.2.0-jar-with-dependencies.jar libraries

You need to use the /fcselect query handler and send the ranker_id as a parameter.
The code below assumes you have a Solr collection with documents and you have trained a ranker, otherwise follow this tutorial.
RetrieveAndRank service = new RetrieveAndRank();
service.setUsernameAndPassword(USERNAME, PASSWORD);
// create the solr client
String solrUrl = service.getSolrUrl(SOLR_CLUSTER_ID);
HttpClient client = createHttpClient(solrUrl, USERNAME, PASSWORD);
HttpSolrClient solrClient = new HttpSolrClient(solrUrl, client);
// build the query
SolrQuery query = new SolrQuery("*:*");
query.setRequestHandler("/fcselect");
query.set("ranker_id", RANKER_ID);
// execute the query
QueryResponse response = solrClient.query(SOLR_COLLECTION_NAME, query);
System.out.println("Found " + response.getResults().size() + " documents!");
System.out.println(response);
Make sure you update the service credentials for RetrieveAndRank(USERNAME and PASSWORD), SOLR_CLUSTER_ID, SOLR_COLLECTION_NAME and RANKER_ID.
The code for createHttpClient() can be found here.

How to add List of comments in Rally java rest API

I have found that if we pass the definition ConversationPosts it will create the comments in Discussion tab. But how to add a list of Conversations to the discussion in Rally Java rest API
JsonObject newDefect = new JsonObject();
newDefect.addProperty("Type", "ConversationPost");
newDefect.addProperty("Text", "Test Comment 2");
newDefect.addProperty("Artifact",defectReference);
newDefect.addProperty("User", userRef);
CreateRequest createRequest = new CreateRequest("ConversationPost", defectObject);
CreateResponse createResponse = rallyRestAPI.create(createRequest);
If we need to add 2 comments say "Test Comment 1" ,"Test Comment 2" to the same defect how this can be done in a single execution

Unfortunately Rally's WSAPI doesn't have any batch create/update endpoints so you'll just have to create your conversation post items one at a time. Your code above looks good.
String[] comments = {"Test Comment 1", "Test Comment 2"};
for(String comment : comments) {
JsonObject newDefect = new JsonObject();
newDefect.addProperty("Type", "ConversationPost");
newDefect.addProperty("Text", comment);
newDefect.addProperty("Artifact",defectReference);
newDefect.addProperty("User", userRef);
CreateRequest createRequest = new CreateRequest("ConversationPost", defectObject);
CreateResponse createResponse = rallyRestAPI.create(createRequest);
}

Adding test cases into TestSets in rally using Java Rally Rest API

I want to add Test cases (already present in Rally in Test folders) into a newly created Test sets using Java Rally Rest API.
Basically every time I want to execute the test cases through Rally I need to create new Test sets and add relevant test cases ( either priority wise, automated/ Manual) in test sets.
Any help on this would be of great help.

Test cases are associated to test sets via the TestCases collection on TestSet in the WSAPI. This code example demonstrates creating a few test cases and then creating a test set associated with the newly created test cases.
RallyRestApi restApi = new RallyRestApi(new URI(SERVER),
USERNAME, PASSWORD);
try {
//Create some test cases
JsonArray testCases = new JsonArray();
for(int i = 0; i < 3; i++) {
JsonObject newTestCase = new JsonObject();
newTestCase.addProperty("Name", "New Test Case " + i);
CreateRequest createRequest = new CreateRequest("testcase", newTestCase);
CreateResponse createResponse = restApi.create(createRequest);
String ref = createResponse.getObject().get("_ref").getAsString();
System.out.println(String.format("Created test case %s", ref));
//Keep track of the test case
JsonObject testCase = new JsonObject();
testCase.addProperty("_ref", ref);
testCases.add(testCase);
}
//Create test set
JsonObject newTestSet = new JsonObject();
newTestSet.addProperty("Name", "New Test Set");
newTestSet.add("TestCases", testCases);
CreateRequest createRequest = new CreateRequest("testset", newTestSet);
CreateResponse createResponse = restApi.create(createRequest);
System.out.println(String.format("Created test set %s", createResponse.getObject().get("_ref").getAsString()));
} finally {
//Release all resources
restApi.close();
}

How to set ResponseWriter to non-default in Solr

I have the following code, which is simply searching the Solr Server.
SolrServer server = new CommonsHttpSolrServer(url);
SolrQuery searchquery = new SolrQuery("company profile");
QueryResponse response = server.query(searchquery)
I want to have the response in json, other than the default which is xml. So I went into the solrconfig.xml file and enabled the following line:
<queryResponseWriter name="json" class="org.apache.solr.request.JSONResponseWriter" />
However, from the console, I'm still getting wt=javabin encoded to the search query request.
Also, I've modified the above code like this:
SolrServer server = new CommonsHttpSolrServer(url);
SolrQuery searchquery = new SolrQuery("company profile");
searchquery.setParam("wt", "json");
QueryResponse response = server.query(searchquery)
But I'm still getting wt=javabin encoded and wt=json also appended, such that the query now looks like this:
webapp/solr path=/select params={wt=javabin&wt=json}
Is there anything I'm doing wrong?
Thanks

SolrJ only supports the javabin and xml formats (configurable with CommonHttpSolrServer.setParser).
But why would you want to use JSON? Javabin is by far the format which provides the best decompression speed, its drawback being that is is not human-readable, on the contrary to JSON and XML (which is not a problem in this case since SolrJ is parsing the result for you).

With SolrJ and json-lib, I was able to get json response like this:
SolrServer server = new CommonsHttpSolrServer(url);
SolrQuery searchquery = new SolrQuery("company profile");
QueryResponse response = server.query(searchquery)
JSONArray jsonObject = JSONArray.fromObject( response.getResults() );
log.log(Level.INFO, "received jsonObject is {0}", jsonObject.toString());
Iterator data = jsonObject.iterator();
SolrResultBean bean = new SolrResultBean();
List output = new ArrayList();
while(data.hasNext()) {
output.add(data.next());
}
log.log(Level.INFO, "json items in the List are {0}", output);
bean.setObject(output);
// wicket page redirect
setResponsePage(SearchPage.class, new PageParameters());
