I just learned the concept behind JSON objects and there use and I'll love to learn handling of JSON with Java and C++, does anybody have any knowledge about using JSON in the two languages and could provide some useful links and information to aid my way?
I've found JSON in general to be great for quickly storing and re-loading large data structures for quick use between models (or saving information so you can pick up where you left off). I've only ever used it in Python but http://www.json.org/ has a great list of JSON libraries for many languages

I am good in java and recently learning scala. I want to develop web application. what are the concepts of scala I need to learn?
There is really nothing specific about Scala and web apps. I would recommend starting with reading play documentation (http://www.playframework.com/documentation/2.1.1/Home) and asking specific questions about stuff you don't understand. Or reading a book on Scala.
I would also suggest to give a try to the Spray toolkit for creating RESTful web-services. It's pretty good for a java developer

I am parsing large amounts of complex files (mostly CSV files but some are not) and I need to structure/parse them into some standard formats. This not only involves row wise cleanup of data but some simple individual cell-based logic. I want a tool that a non-programmer can use also so a business team member can write simple drag and drop logic and not take up engineering time. So far, I have looked at Google Refine and Data wrangler and the last one looks great. Are there any other such tools out there?
ETL tools are oriented more towards relational databases, but also have support for XML and CSV file input/output. Examples:
http://www.talendforge.org/
http://kettle.pentaho.com/
Could easily be too complicated for your requirements though. Also, see this similar question on SO (with additional links): What software is availible for data quality checking .

I was looking for a open source library for generating automated summaries out of few words. For ex: if two qualities are given of a person a) good thinking skills b) bad handwriting, i need to generate a sentence like "Bob has good thinking skills however needs to improve on his handwriting". I need to know if any open source library could help me achieve it even partially.
Thanks for help!

You could start with MEAD. Not sure what sort of mileage you'll get with single-sentence summarization, but you may be able to do some post-processing on the output and manage it.
It would take a bit of work, but you could also construct something out of NLTK and one or more the associated databases (eg. WordNet). Python, open source.

I'm using QT for Symbian and need a simple json parser. I need to be able to go from json to Qt-variant and the other way around. Is there a simple json parser that I can use? I don't want to write my own.
You need no Additional code except QT itself to parse JSON with QT
http://doc.qt.io/qt-5/json.html
Check out Qt-Json
Its a dead-simple class for parsing and serializing JSON data.
The qjson project may be a good start. It has also been packaged for Debian.
I wrote a QLALR based JSON parser : http://git.forwardbias.in/?p=qjsonparser.git.
git clone git://git.forwardbias.in/qjsonparser.git.

My main purpose is to have a generic data buffer that I can use for transfers.
I'm thinking of something along the lines of what XCopy did.
Is there something already made out there or a good example one can follow?
The Tomes of Delphi by Julian Bucknall describes code for circular buffers, the code of which is freely available as a download. I haven't got the book to hand at the moment, so I can't tell you exactly where to look (though I think it might have had something to do with carrying out data compression with a sliding window).
