I am Developing an application using Spring MVC and JSP, what am trying to do is fetch some data from a URL, the URL's data is in JSON encoded multidimensional map.
For Example:
{"RT":"32",
"HED":{
"COMPINF":{
"CP":"ISIN_CODE|SECTOR|LANGUAGE_CODE"}}}
I want to parse this code in the same way it came to me, I was trying to use a multidimensional hashmap but can't realy figure out a way.
What would be the best way to parse this data ?
You'll want to use a JSON parser such as Google Gson (https://code.google.com/p/google-gson/)

Want to create a tabular report from Java using JSON file. I have an 861 kb Json report with me.
Kindly suggest me the approach need to be followed.
It sounds like your input is JSON. You did not specify an output format. But similar as in HTML you could place tabular data into JSON as well. Assuming that is the case, all you need is a JSON parser/serializer and inbetween some Java code to adapt one format for the other.
To transfer one XML data structure into another XML data structure there are nice tools like XSLT. Some of the implementations can also be used for JSON documents. See https://stackoverflow.com/a/49011455/4222206
With the above assumption your code would perform these steps:
Parse input JSON
Run XSLT for JSON
Serialize the obtained output
I am working to retrieve data from an API call. For the login part, a simple text response is sent by the site to which I am connecting.
Sample response is given below:
{"code": "OK",
"data": {"session_id": "myemail#domain.com:uJoaY1KlTWBchJpGHeZVZWs3"},
"user": "myemail#domain.com"}
I want to extract the various values from above response. What kind of object do I have to create that maps correctly to each of the elements in the response? Also, I thought of using a hashmap as part of my object- is that the correct approach? What is the best way to map the above data to a Java object?
That data is in JSON format. There are several Java libraries to parse JSON data, for example Google GSON.
I want to do some application to learn how to work with android and maps. So I want to make something simple, like showing on the map the schools or museums from a given city.
I think I have to use the Google Places API, so I read some things about it. I saw that I have to make some request to a rest server, and they will return me a json response. I understand that. But, what I don't understand is how can I "translate" those json responses into pinpoints on the map.
If you can guide me to some tutorials or some examples with this, I would appreciate that. I saw some links right here, on SO, but they were incomplete or not working.
Thanks
you use the json data as follows:
var a=new JSONObject(jsonData);

Use the data from a to constuct the necessary objects and add it to the map.

I have a large collection of twitter messages from the streaming twitter API saved as JSON strings in text files.
I wanted to know if anyone knew how I could convert these JSON strings into something like the Twitter4J status object for use as a simple object with getters and setters?
I was thinking about debugging the source and writing my own inject class which would mimic the input stream classes, however I wonder if there is a better way..?
Thanks!
Try DataObjectFactory#createStatus(String). It's a simple static method that returns one single twitter4j.Status object.
http://twitter4j.org/en/javadoc/twitter4j/json/DataObjectFactory.html#createStatus(java.lang.String)
You can try using Google's Protobuff or Codehause's XStream or Jackson

Depends on what you want to do with the data. One thought that comes to mind is importing it into a database like MongoDb which already has support for importing JSON http://www.mongodb.org/display/DOCS/Import+Export+Tools . then you can proceed to analyse or convert the data further from there
I don't know whether this question makes sense or not.
I have huge amount of JSON data with me. I am getting that data from Server to the Client side.
Is it good idea to serialize the JSON object in server side ?

No. JSON is already serialized, that's the point of the format.
If you have non-JSON data that you want to deliver to the client then, unless it is a string, you have to serialize it so that it is in a transmittable format.
Check out GSON
