Integrating 3rd party API with jhipster based webapp

I am trying to build a simple web app using jHipster. Currently I am trying to build a simple stock entity that will enable a user to input the stock name and the entity should generate a listing of that stock with open, high, low and close data. I am unable to figure out how to integrate the web app with a third party API that supplies the data. I could not find any documentation regarding this issue online. Thank you.

I found this tutorial on implementing API's that might help.
What you need to do is create an HTTP client that can access your API.
I'm not too familiar with jHipster but finding the proper library to import seems like a good first step. Good luck.

If you aren't sure which language to choose, a great way to narrow down the selection can be to find an API you want to implement and see if the company provides a client library. A library is code that the API owner publishes that already implements the client side of their API. Sometimes the library will be individually available for download or it will be bundled in an SDK (Software Development Kit). Using a library saves you time because instead of reading the API documentation and forming raw HTTP requests, you can simply copy and paste a few lines of code and already have a working client.

how to add facility like google docs has in my project

I want to create maven project like compare to office docs with it syntax. So I think to download Google docs API.
But I didn't find any link to download it. so any API that do this or download link and sample for achieve it using Google docs or other.

You can't download Google docs the same way you download an Office file. Even the Google docs inside of the Google Drive are actually just links.
What you have to do instead is learn how to interface with the API. This will allow you to manipulate Google docs.

How to build a full text search similar (as quick & as accurate) to Google Drive?

Google Drive searching is really amazing.
It built up a full text search index instantly right after I had uploaded the document(pdf/M$ office document).
Since I want to use this technology in my own GAE project,I was wondering
1.is there any existing api from(Google/others) provide this function
2.how to implement by myself.

On App Engine you can use Search API, to do full-test indexing & querying.

You can use following options.
Google desktop and not sure about api.
IIS index server thenyou can do query it index files too.
Dtseach is tool with api but paid.
Apache api i forgot name but will post it shortly.

Document type "externalapp" - what is it?

Trying to download docs from the Google Docs using Java client library and getting some documents with type "externalapp".
What is this type and what is the proper way to handle such kind of files?

Those can be shortcuts created by third-party applications that integrate with Google Drive using the Drive SDK but store their data in a different storage system: https://developers.google.com/drive/apps_overview

Google transliteration API in Java Swing project

I'm working on a transliteration project in Java Swing. It can access the internet, but I'm unable to set it up. How do we do that? Do we need to download the Google API libraries or just a function call will do?
Here are some useful Transliteration links:
The Google Transliterate API Devloper's Guide
Google API library for Java for download
(I think it has all API libraries of Google:Translate, transliterate, search, etc.)
I spent a lot of time, but Icouldn't find how to set up the Transliteration API, not even at SO.

Seems the transliteration API is deprecated and is not included in the Java client, only in the JavaScript client.
The actual calls the JS library makes are pretty simple and could easily be replicated from anywhere:
http://www.google.com/inputtools/request?ime=transliteration_en_ru&num=5&cp=0&cs=0&ie=utf-8&oe=utf-8&text=prosto
Don't know if doing that is against Google's terms, though. Probably it is.
You could also try running the Ajax client in Rhino. You'll need env-js which provides a pure javascript DOM environment.
It's just hideous enough to work!
