I have a .NET WebService that I'd like to access through a WinForms and a Java application.
As of now I only get the datagridview filled rows and columns contaning probably the length of the string(?). And I haven't found a way for Java to interpret the List
I would like to be able to fill rows and columns in both the JTable in Java as well as the datagridview in WinForms/C#. Therefore I wonder if perhaps a 2d-string array is better, since I will be able to define both columns and rows?
This is the asmx web-service c# class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

I'm kind of new to the MongoDB Java driver and I was wondering how you could execute a query stored as a string. Is this the best way to execute them, or what would be a better approach?
I've stumbled across the piece of the below on another stackoverflow thread, but haven't been able to get anything useful out of it. The output does not contain the result of the query at all.
The code I'm running right now:
#Test
public void testExecuteStoredQueries() {
String code = "db.getCollection('users').find({})";
final BasicDBObject command = new BasicDBObject();
String formattedCode = String.format("function() { return %s ; }", code);
System.out.println("Formatted code:");
System.out.println(formattedCode);
command.put("eval", formattedCode);
Document result = DbEngine.getInstance().getDatabase().runCommand(command);
System.out.println(result.toJson());
}
Summarized output:
{
"retval": {
"_mongo": "....",
"_db": "...",
"_collection": "...",
"_ns": "cezy.users",
"_query": {},
"_fields": null,
"_limit": 0,
"_skip": 0,
"_batchSize": 0,
"_options": 0,
"_cursor": null,
"_numReturned": 0,
"_special": false
},
"ok": 1
}
I use morphia when i have to deal with objects. As when you retrieve the data from MongoDb, for the long values you get extended Json instead of Json Response. Parsing Extended Json could be a trouble and might break the code. As Gson doesn't support the conversion from Extended Json to Json.
private void createDatastore(boolean createIndexes) {
Morphia morphia = new Morphia();
morphia.map(classname.class);
datastore = morphia.createDatastore(mongoClient, databaseName);
if (createIndexes) {
datastore.ensureIndexes();
}
}
#Override
public Datastore getDatastore() {
return this.datastore;
}
#Test
public void testExecuteStoredQueries() {
String code = "db.getCollection('users').find({})";
String formattedCode = String.format("function() { return %s ; }", code);
final BasicDBObject basicObject = new BasicDBObject(new BasicDBObject("$in", formattedCode));
Query<ClassName> query = getDatastore().createQuery(<Classname>.class).filter("_eval", basicObject);
List<Classname> List = query.asList();
//if you want to access each object and perform some task
List.forEach((cursor) -> {
//perform your task
});
}
Removing the function creation and adding ".toArray()" pretty much solved the problem.
#Test
public void testExecuteStoredQueries() {
String code = "db.users.find({}).toArray();";
final BasicDBObject command = new BasicDBObject();
command.put("eval", code);
Document result = DbEngine.getInstance().getDatabase().runCommand(command);
System.out.println(result.toJson());
assertNotNull(result.get("retval"));
}
The array is in the "retval" field of the response.
I have this application in Flink which use Table API to print data from a source. THe official documentation of Flink says that the Table API uses Calcite on its core to translate and optimize query plans. They don't describe it very in deep, so I went to the source code and tried to copy some codes from there. But, as far as I saw, they use Calcite rules as well.
What if I want to implement my own rule? Is it possible? How do I implement a simple rule in Calcite to change the parameter of a filter for example?
Here is my code
public class HelloWorldCalcitePlanTableAPI {
private static final Logger logger = LoggerFactory.getLogger(HelloWorldCalcitePlanTableAPI.class);
private static final String TICKETS_STATION_01_PLATFORM_01 = "TicketsStation01Plat01";
public static void main(String[] args) throws Exception {
new HelloWorldCalcitePlanTableAPI("127.0.0.1", "127.0.0.1");
}
public HelloWorldCalcitePlanTableAPI(String ipAddressSource01, String ipAddressSink) throws Exception {
// Start streaming from fake data source sensors
StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();
env.setStreamTimeCharacteristic(TimeCharacteristic.EventTime);
// StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env, tableConfig);
StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env);
// Calcite configuration file to change the query execution plan
// CalciteConfig cc = tableEnv.getConfig().getCalciteConfig();
CalciteConfig cc = new CalciteConfigBuilder()
.addNormRuleSet(RuleSets.ofList(MyFilterReduceExpressionRule.FILTER_INSTANCE))
.replaceDecoRuleSet(RuleSets.ofList(MyDataStreamRule.INSTANCE))
.build();
tableEnv.getConfig().setCalciteConfig(cc);
// obtain query configuration from TableEnvironment
StreamQueryConfig qConfig = tableEnv.queryConfig();
qConfig.withIdleStateRetentionTime(Time.minutes(30), Time.hours(2));
// Register Data Source Stream tables in the table environment
tableEnv.registerTableSource(TICKETS_STATION_01_PLATFORM_01,
new MqttSensorTableSource(ipAddressSource01, TOPIC_STATION_01_PLAT_01_TICKETS));
Table result = tableEnv.scan(TICKETS_STATION_01_PLATFORM_01)
.filter(VALUE + " >= 50 && " + VALUE + " <= 100 && " + VALUE + " >= 50")
;
tableEnv.toAppendStream(result, Row.class).print();
System.out.println("Execution plan ........................ ");
System.out.println(env.getExecutionPlan());
System.out.println("Plan explaination ........................ ");
System.out.println(tableEnv.explain(result));
System.out.println("........................ ");
System.out.println("NormRuleSet: " + cc.getNormRuleSet().isDefined());
System.out.println("LogicalOptRuleSet: " + cc.getLogicalOptRuleSet().isDefined());
System.out.println("PhysicalOptRuleSet: " + cc.getPhysicalOptRuleSet().isDefined());
System.out.println("DecoRuleSet: " + cc.getDecoRuleSet().isDefined());
// #formatter:on
env.execute("HelloWorldCalcitePlanTableAPI");
}

I'm trying to use the upsert feature of mongodb v3.2 using java,
so every solution not including a java response would not be accepted.
My problem is that the upsert command override nested objects instead of adding new ones, I have tried to use '$addToSet' and 'push', but without success and I get an error message indicating that the storage engine does not support this command.
I want to update the client's document as well as their inner objects such as checks and checks's values.
the global structure of the client doc is as below.
Client
|
|__Checks // array of checks , update or insert operation
|
|__values // array of values, every check has its own values (20 max)
// update using index(id)
link of the: Example's source code
My intention is to use only one query to update client's document without using many queries.
I'm not specialist in mongodb, so every advice or critics would be appreciated.
Even if I'm doing this all wrong, feel free to notify me, and please using java for mongo 3.2.
Here is the source code used to generate the last result.

You may use $push, $each, $slice to solve your problem, see alse https://docs.mongodb.org/manual/reference/operator/update/slice/.
db.students has following documents
{ "_id" : 10, "scores" : [ 1, 2, 3 ] }
db.students.update(
{ _id: 10 },
{
$push: {
scores: {
$each: [ 4 ],
$slice: -3
}
}
}
)
result is:
{ "_id" : 10, "scores" : [ 2, 3, 4] }
I wrote a Bottom up web service in java. The service code is like the following:
#WebService(serviceName="CPService", name="CPService")
#SOAPBinding(style=SOAPBinding.Style.DOCUMENT, use=SOAPBinding.Use.LITERAL, parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
public class CPService {
#WebMethod(operationName = "SendSms")
#WebResult(name="SendResult")
public SendResult sendSms(#WebParam(name = "smses") Sms[] smses){
SendResult result = new SendResult();
if(smses == null || smses.length == 0){
result.OperationResult = OperationResult.MaxSizeExceed.getValue();
return result;
}
result.OperationResult = OperationResult.Success.getValue();
SmsResult[] smsResults = new SmsResult[smses.length];
int i = 0;
for (Sms sms : smses) {
smsResults[i++] = new SmsResult(sms.Index);
}
result.SmsResults = smsResults;
return result;
}
}
#XmlRootElement(name="SmsResult")
public class SmsResult {
#XmlElement(required = true, name="Index")
public int Index;
#XmlElement(required = true, name="BrtelId")
public String BrtelId;
public SmsResult(){}
public SmsResult(int index){
this.Index = index;
this.BrtelId = UUID.randomUUID().toString();
}
}
Then I created a C# based client and I tried to call service. Service call was Ok but return values was null. After some try I understand that the problem was related to deference between array serialization in C# and Java.
I want to know is there any way to handle WSDL generation process(for exmaple using XmlElementWrapper decorator)?
Currently, I want to return the return xml result with XML with the below format :
I tried to use something like this
#XmlRootElement(name = "item")
public class Book implements Serializable {
#XmlAttribute
public int getBookId() {
return bookId;
}
...
....
and
#XmlRootElement(name = "OneBoxResults")
public class JavaClazz {
private List<Book> OneBoxResults;
public List<Book> getOneBoxResults() {
return OneBoxResults;
}
#XmlElements(#XmlElement(name = "book", type = Book.class))
public void setOneBoxResults(List<Book> oneBoxResults) {
OneBoxResults = oneBoxResults;
}
...
However, the return result which I received is only Json format as below :
{"oneBoxResults":[{"bookId":1,"bookName":"Search
Deployment","update":"2014-01-07","description":"A successful deployment
typically involves the following
elements:","path":null},{"bookId":2,"bookName":"GSA
Information","update":"2015-01-07","description":"Configure the OneBox
module so it sends search queries to the provider (a custom
application","path":null}]}
I also attemped to create new format in controller as below :
#RequestMapping(value = "/rest.oneboxSample",produces = MediaType.APPLICATION_XML_VALUE, method = RequestMethod.GET)
public #ResponseBody String oneboxSample(){
String tmpOpenField = "<Field name=\"";
String tmpCloseField = "</Field>";
StringBuilder builder = new StringBuilder();
builder.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
builder.append("<OneBoxResults>").append("<resultCode>");
builder.append("Listbook").append("<resultCode>");
for(int i = 0; i < bookDao.getBooks().size(); i++){
Book tmpBook = bookDao.getBooks().get(i);
builder.append("<MODULE_RESULT>");
builder.append(tmpOpenField).append("bookId\">").append(tmpBook.getBookId()).append(tmpCloseField);
builder.append(tmpOpenField).append("bookName\">").append(tmpBook.getBookName()).append(tmpCloseField);
builder.append(tmpOpenField).append("update\">").append(tmpBook.getUpdate()).append(tmpCloseField);
builder.append(tmpOpenField).append("description\">").append(tmpBook.getDescription()).append(tmpCloseField);
builder.append(tmpOpenField).append("path\">").append(tmpBook.getPath()).append(tmpCloseField);
builder.append("</MODULE_RESULT>");
}
builder.append("</OneBoxResults>");
return builder.toString();
}
But the result is not good. It returned a string instead of xml format which we need.
Now, our system need to receive a xml format instead of an original xml format.
Please tell me know the way to do it .
The below is my source code which I wrote
https://www.dropbox.com/s/4tyg0kp7gkzodod/onebox-service.zip?dl=0
