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 am looking for the open source API if there is any available which can convert javax.mail.Message object to XML specific format or some sample code if there is any already exist ?
Please let me know if you know any.
Thanks.
The way I've always done it is by using the DOM parser. Message provides methods to grab every part of the mail (recipients, body, sender...). With that, you can just create your Elements and Attributes and you should be sorted. As far as I'm aware, there is not library that will do that for you.
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/)
edit: Here is a similar question: Converting JSON to Java
Is there a Json - parser for java online that can help me to create Java - objects from Json-string? (I found similar one but there I can translate json-string in Java -objects only if I have url for my json-string)?
Thanks for the link, this should be easy:
upload your JSON string to a site like pastebin.com
get the RAW link, i.e. the one without the PasteBin website around)
put that into http://jsongen.byingtondesign.com
Have a look at http://jackson.codehaus.org/
But be sure that you really want to put it into Java objects, because whenever the JSON representation changes, translation will break of course.
QuickType.io is exactly what you're looking for.
For the record, I'm unaffiliated.
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);
http://developer.android.com/resources/tutorials/views/hello-mapview.html
Use the data from a to constuct the necessary objects and add it to the map.

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
