Using Rest assured to validate saved JSON response - json

I have a question regarding REST Assured. - https://code.google.com/p/rest-assured/wiki/Usage
I understand that I can use REST assured to make HTTP calls(.get .put etc.) and validate the response using when() etc. I would like to validate JSON responses that I have already saved in the database, instead of Calling the web service realtime and validating it's response.
Can I use REST-assured to Load a JSON response as a String and validate it?

Yes you can use Rest Assured's JsonPath project independently of Rest Assured (see getting started page). Once you have it in classpath you can do something like this:
JsonPath jsonPath = new JsonPath(<your json as string>);
String title = jsonPath.getString("x.y.title");

NodeJS Joi Vlidation - How to return JSON response instead of a string?

Recently, Iv'e been using the Joi validation library in-order to validate the data which comes in from a request (building a RESTful API).
I was using the .label() method to generate a string response and send it back to the user, but I couldn't find any way to send a JSON response back to the user?
Tried sending a premade JSON inside the string, searching the documentation and the internet of course - couldn't find any mention of it.
Current code example:
textField: Joi.string().required().max(4).label("This example field didn't pass the testing phase, please try again)"),
Any ideas?
If you need to send data in case of error,try .error() method. you can pass error in it.

How to convert a servlet request to a JSON request

I had an application that is running with servelets. I want to test that application using REST services or POSTMAN.
So, I want to know, whether it could be possible to convert a servelet application's request and response into JSON for testing it with Postman or REST services.
If this possible, how do I do this conversion?
Some context would be helpful. What does the request to your application look like?
You don't need to convert an application's request / response into JSON to use postman. Postman is pretty flexible, you can send a variety of request content types to your application.
As far as whether or not this is possible, absolutely. If you want to convert your request & response objects to JSON, consider using something like Jackson. You can use the ObjectMapper of this tool to go from JSON to POJO & vice versa

Pass JSON object vs JSON string in HTTP POST

I'm building a REST API in JAVA and C# and I was wondering about the way I should pass data to those services.
What I'm familiar with as the right way is to send JSON object as the data in the POST body:
{name:'Dor'}
but I can also pass a string and parse the JSON in my service:
'{name:'Dor'}'
What is the preferable way from performance factor? or any other factors?
Basically, if you need to send the json data across via jquery, then we need to use stringify, else the data would be serialized into to key=value pair.
So, you cannot send the json object directly via jquery ajax method.
How it works behind the hood:
In $.ajax function, if we provide data as
data :{key1:"value1", key2:"value2"}
is serialized to key1=value1&key2=value2
if we provide data as
data :'{key1:"value1", key2:"value2"}' or JSON.stringify({key1:"value1", key2:"value2"})
is sent as {key1:"value1", key2:"value2"}
So, what we can conclude is that, we cannot pass json object directly via jquery, we can send only json string. Hope this clarifies everyone.

use a rest webservice response in another request using jmeter

suppose I have a webservice that generate random password and return json response, this password is used in the following request. is there anyway to do this in jmeter, i.e to extract the password from the first response and use it in the next request
We have Regualr Expression Extractor Or JSON Path Extractor in JMeter to extract the values from 1 response & use it in subsequent requests.
As Vinoth S said, JSON extractor is the way to go. You can download it from here. Document how to use it is here. Just put it in request from which you want to extract, type vairable_name that you will use in the next request as ${variable_name}, JSON Path is quite easy to set, probably, if the response is not to complicateg just the property name from JSON will be enough, or something like $.varName and you're ready to go.

Paypal API: NOT json response

I'm trying to execute example from here: https://developer.paypal.com/docs/classic/paypal-payments-pro/gs_PayPalPaymentsPro/
curl -s --insecure https://api-3t.sandbox.paypal.com/nvp -d "USER=platfo_1255077030_biz_api1.gmail.com&PWD=1255077037&SIGNATURE=Abg0gYcQyxQvnf2HDJkKtA-p6pqhA1k-KTYE0Gcy1diujFio4io5Vqjf&METHOD=DoDirectPayment&VERSION=78&PAYMENTACTION=SALE&AMT=5&ACCT=4660997962602322&CREDITCARDTYPE=VISA&CVV2=176&FIRSTNAME=James&LASTNAME=Smith&STREET=FirstStreet&CITY=SanJose&STATE=CA&ZIP=95131&COUNTRYCODE=US&EXPDATE=092015"
Documentation says:
Request method, format Response format
HTTP GET Name/value pairs JSON
But I receives:
TIMESTAMP=2015%2d01%2d30T12%3a14%3a08Z&CORRELATIONID=474de7dae8e82&ACK=Success&VERSION=78&BUILD=15009693&AMT=5%2e00&CURRENCYCODE=USD&AVSCODE=X&CVV2MATCH=M&TRANSACTIONID=93V64243P1844913T
Why? How to get json response?
I tried to set:
VERSION=95
but didn't help.
As document states the paypal NVP api doesn't straight away provide json response.
The way attained to process the response goes like below,
In PHP
parse_str($response,$responseArray);
$jsonResponse = json_encode($responseArray);
helped me to get the array from the response string and in turn converted to json.
Edit : you first need to decode the urlencoded string.
For that
$response = urldecode($response);
Before parsing the response to array.
While I do see the documentation you quoted (from https://developer.paypal.com/docs/classic/paypal-payments-pro/gs_PayPalPaymentsPro/), I think it's flat-out wrong.
I don't believe the classic PayPal APIs support JSON (except Adaptive Payments, which was written later # PayPal & is thus a bit more modern in some ways, including the JSON support).
See https://developer.paypal.com/docs/classic/api/gs_PayPalAPIs/, which describes the headers taht you can use to request JSON from the Adaptive APIs but clarifies that the other classic APIs don't support it.
