How to convert string to MarketDataIncrementalRefresh in QUICKFIX in Java? - java

I am working on the Stock and Exchange Markets. I have a situation like : I need to take a string from the log and convert it to "Message" type Object. As per this link I have tried using all the three methods of the "MessageUtils" class in JAVA. But my String is being stripped to a Message class type object with unique tags. But as my string is "MarketDataIncrementalRefresh" type I want each every tag to be present in the Message.
For example : I am providing the following string to "MessageUtils.parse()" method.
8=FIX.4.2|9=00795|35=W|49=TT_PRICE|56=SAP0094X|34=2392|52=20170623-04:41:33.375|55=CL|48=00A0HR00CLZ|10455=CLQ7|167=FUT|207=CME|15=USD|262=MDRQ-751|200=201708|18210=1|387=12292|268=24|269=0|290=1|270=4290|271=33|269=0|290=2|270=4289|271=34|269=0|290=3|270=4288|271=40|269=0|290=4|270=4287|271=38|269=0|290=5|270=4286|271=46|269=0|290=6|270=4285|271=53|269=0|290=7|270=4284|271=46|269=0|290=8|270=4283|271=66|269=0|290=9|270=4282|271=48|269=0|290=10|270=4281|271=64|269=1|290=1|270=4291|271=21|269=1|290=2|270=4292|271=40|269=1|290=3|270=4293|271=48|269=1|290=4|270=4294|271=83|269=1|290=5|270=4295|271=62|269=1|290=6|270=4296|271=46|269=1|290=7|270=4297|271=34|269=1|290=8|270=4298|271=55|269=1|290=9|270=4299|271=31|269=1|290=10|270=4300|271=128|269=2|270=4291|271=1|269=4|270=4280|269=7|270=4292|269=8|270=4277|10=044|
But what I am getting is this:
8=FIX.4.2|9=192|35=W|34=2|49=TT_PRICE|52=20170622-14:16:23.685|56=SAP0094X|15=USD|48=00A0HR00GCZ|55=GC|167=FUT|200=201708|207=CME|262=MDRQ-21|268=25|269=0|270=12510|271=24|290=1|387=121890|10455=GCQ7|18210=1|10=036|
As you can observe only unique tags are present in the String. But I want each and every tag , no matter how many times it exists in the provided string.
Please can anyone help me doing this in JAVA. It will be really appreciable.
Below is the code I am using for converting :
MessageUtils mu = new MessageUtils();
Session session = Session.lookupSession(sessionID);
Message msg = MessageUtils.parse(new DefaultMessageFactory(), null, str);
// Message msg = new Message(str, false); //This can also be used for converting
System.out.println(msg.toString());

The other thread says:
MessageUtils.parse(MessageFactory messageFactory, DataDictionary dataDictionary, java.lang.String messageString)
And your code says:
Message msg = MessageUtils.parse(new DefaultMessageFactory(), null, str);
So you need to fix your data dictionary and pass it to the parse method instead of passing 'null'

I think the problem is as follows. There's a repeating group that starts with tag 286 (NoMDEntries). The order of fields in a repeating group should be strict, i.e. the same order as the definition of the repeating group. See Market Data - Snapshot/Full Refresh or the data dictionnary supplied by QuickFIX/J (FIX42.xml).
The 268 tag should be followed by 269 and then 270. I am seeing in your message string: |268=24|269=0|290=1|270=4290| which is the incorrect order of tags. That is probably the reason why the message is truncated by MessageUtils.parse.
As a test you could try to manually correct the order in the string and try parsing that to see if that gives the correct message.

GMail API aliases.getSendAs().get(0).getDisplayName returns empty (only for 0, not for the next ones)

I'm using Java GMail API and everything is working good for sending e-mails, collecting data from my profile, etc.
The only problem is that, while I can get the Signature for my 0-th element of the list of SendAs aliases, I can't get the Display Name: it returns an empty String. Both work for the other aliases (get(1) and subsequent numbers). It seems that the problem is on 0, tried on different authenticated users with Name set and it remains the same.
ListSendAsResponse aliases = service.users().settings().sendAs().list("me").execute();
SendAs mimmo = aliases.getSendAs().get(0);
actualsign = mimmo.getSignature();
sendername = mimmo.getDisplayName();
In Gmail API, there are two different ways to retrieve alias(es):
getSendAs() and SendAs.Get(java.lang.String userId,java.lang.String sendAsEmail)
The first one returns you a list of all alias, the second returns you one alias ressource - the one with the specified userId and sendAsEmail parameters.
If what you want to do it to retrieve the first element of the getSendAs() response, you should do it with getSendAs()[0] and not with the Java method get.
Sample:
SendAs mimmo = aliases.getSendAs()[0];
System.out.println(mimmo.getDisplayName());
It is always useful to test with the Try this API what response a method returns. Thereby, the userId can be set to me.

Listing the parameters in a node using RESTassured library with Java

The webservice: http://services.groupkt.com/country/search?text=lands has 16 records returned from a GET request. In the records, there is a parameter called 'name'. So, there are 16 names and each name has a unique value (country). My intention is to list all the 16 values of the 'name'parameter using java and the RESTassured library. I tried this:
Response response = RestAssured.get("http://services.groupkt.com/country/search?text=lands").andReturn();
String json = response.getBody().asString();
JsonPath jp = new JsonPath(json);
List<String> ls = from(response).getList("RestResponse.result.name");// The 'from' text displays an error
An error was seen on the 'from' text and it says: The method from(String) in the type RestTest is not applicable for the arguments (Response). I am not sure how to rectify this. Is there a simple way to create a list of all the values of the 'name' parameter?
Try replacing from(response) to from(jp). That should take care of the error you are getting.
The Response class (which is what the get() method returns) also supports jsonPath, so you could also refactor it to something like this:
List names= get("http://services.groupkt.com/country/search?text=lands").jsonPath().getList("RestResponse.result.name");

Rally REST Query throwing MalformedJsonException

I'm trying to query something from the Rally database. Right now I'm just trying to make sure I can get through initially. This code:
//create rallyrest object
RallyRestApi restApi = new RallyRestApi(new URI(hostname), username, password);
restApi.setApplicationName("QueryTest");
restApi.setWsapiVersion("v2.0");
restApi.setApplicationVersion("1.1");
System.out.println("1: So far, so good -- RallyRestApi object created");
try {
//create query request
String type = "HierarchicalRequirement";
QueryRequest qreq = new QueryRequest(type);
System.out.println("2: Still going -- Query Request Created");
//set fetch, filter, and project
qreq.setFetch(new Fetch("Name","FormattedID"));
qreq.setQueryFilter(new QueryFilter("Name", "contains", "freight"));
qreq.setProject(projectNumber);
System.out.println("3: Going strong -- Fetch, Filter, and Project set");
//create response from query********Blows up
QueryResponse resp = restApi.query(qreq);
System.out.println("4: We made it!");
} catch (Exception e) {
System.out.println("Error: " + e);
}
finally {
restApi.close();
}
}
gives me this error:

Could someone please explain why this is happening? Is my code wrong? If I need to do as the error suggests and set Json.lenient(true), please give me instructions on how to do that with my code.
Thank you!
Your code works for me. I don't see anything wrong with the code.
Try different query, maybe there are some extra characters.
See this post - it mentioned a case with trailing NUL (\0) characters. Perhaps you need to set lenient to true, but I don't know how to do it: there is no direct access to it when working with Rally QueryResponse.
The reason for trying a different query is that there are two local factors: your java environment and your data. MalformedJsonException indicates bad json which points to data. You are fetching only "Name" and "FormattedID", so chances are the culprit is somewhere in the name. Try a different query, e.g. (FormattedID = US123) but choose the story that does not contain "freight" in the name. Establish that at least one particular query works - it will indicate further that the issue is indeed related to data, and not the environment.
Next, try the same query (Name contains "freight") directly in WS API, which is an interactive document where queries can be tested. An equivalent of the query in your code can also be pasted in the browser:
https://rally1.rallydev.com/slm/webservice/v2.0/hierarchicalrequirement?workspace=https://rally1.rallydev.com/slm/webservice/v2.0/workspace/123&query=(Name%20contains%20%22fraight%22)&start=1&pagesize=200&fetch=Name,FormattedID
Make sure to replace 123 in /workspace/123 with the valid OID of your workspace.
Does the query return or you see the same error in the browser?
If the query returns, what is the TotalResultCount?
The total result count will help to troubleshoot further. You may run your code one page at a time, and knowing the TotalResultCount it is possible to manipulate pagesize, start and limit to narrow down your code to the page where the culprit story exists (assuming that there is a culprit story). Here is an example:
qreq.setPageSize(200);
qreq.setStart(2);
qreq.setLimit(200);
Maximum pagesize is 200. Default is 20. The actual number to use depends on TotalResultCount.
The start index for queries begins at 1. The default is 1. In this example we start with second page

Jena model.write get InvalidPropertyURIException

I' m using jena, and get this exception when writing the model. I don' t know why it doesn' t tell you when you create the property URI.

Currently I use
DatatypeProperty datatypeProperty = model.createDatatypeProperty(nameSpace+URIref.encode(string));
to create the datatype property, using URIref.encode to encode the string, is it wrong?
The com.hp.hpl.jena.xmloutput.impl.BaseXMLWriter.splitTag does not accept this property URI. See also com.hp.hpl.jena.rdf.model.impl.splitNamespace and code examples http://www.programcreek.com/java-api-examples/index.php?api=com.hp.hpl.jena.vocabulary.XSD (search for createDatatypeProperty):
String ns = "http://www.example.org/test#";
DatatypeProperty p = model.createDatatypeProperty( ns + "p" );

How to write a http get request when a key's value is an array?

I have written a java servlet to deal with http get request.I know ,the common format of get request is like this:http://IP_ADDRESS:8080/test?name="jack"&value="shit.
But now ,I have a list of values to transfer,such as an user id list[1,2,3,4].So ,my question is ,how should I write my http get request to express this?And in java servets doGet(),can I use request.getParameterValues to get such an array?
if you are using GET method your url should be looking like that :
http://IP_ADDRESS:8080/test?list=1&list=2&list=3
for retrieving it:
String[] arrlist=request.getParameterValues('list');
your array will be filled with separated values:
//["1","2","3"]
UPDATE : if to write it list[] or list?
when you retrieving your list parameters it wouldn't be parsed as array but as a series of String which will be grouped later on into an array.
Which means even if you write it list[]=1&list[]=2&list[]=3, list[=1&list[=2&list[=3, list*=1&list*=2&list*=3 or list=1&list=2&list=3 it would always be giving you the same answer whether you retrieve it as
request.getParameterValues('list[]') //["1","2","3"]
request.getParameterValues('list[') //["1","2","3"]
request.getParameterValues('list*') //["1","2","3"]
request.getParameterValues('list') //["1","2","3"]
While ,the http request format should be like this:localhost:8080/test?list[]=1&list[]=2&list[]=3
Maybe too simple, but what about repeat parameters name?
http://IP_ADDRESS:8080/test?userId=1&userId=2&userId=3
