I have the WSO2 Developer Studio Eclipse Plugin downloaded. And I was looking at this tutorial: http://wso2.com/library/tutorials/2010/07/eclipse-bpel-designer-wso2bps-tutorial/. But it seems to be talking about using SOAP. But my webservices, which are written in PHP(in live servers) are REST using JSON. Accepts data via HTTP GET methods by these webservices and respond back with JSON data.
So how will I implement a BPEL project making use of the JSON webservices? Any ideas or suggestion? Am completely new to this. Thank you.
EDIT
When I created the BPEL Process, I have used HTTP from the dropdown instead of SOAP
WSO2 uses a custom variant of the Apache ODE engine for executing BPEL processes. ODE provides extensions for REST, which you can try out. However, I am not sure if these extensions also support JSON or if they just allow XML data. Also have a look at this answer.

Just started working on an existing project making use of the Exact Online API.
While I was debugging the project I suddenly only started receiving XML results instead of JSON results from the API. I did not change anything about the endpoints being queried I was just running the existing queries trying to figure some things out.
These are the REST API docs: https://start.exactonline.nl/docs/HlpRestAPIResources.aspx
These are the XML docs: https://support.exactonline.com/community/s/knowledge-base#All-All-DNO-Content-xmlsamplecode
Typical REST API endpoints look like this:
https://start.exactonline.be/api/v1/xxxxxx/salesinvoice/SalesInvoices
Typical XML endpoints look like this:
https://start.exactonline.be/docs/XMLDownload.aspx
I also did not change any settings. I only have access to the tokens and api. I don't have access to the account.
This is an example of an endpoint and query where I previously received JSON but am now receiving XML:
https://start.exactonline.be/api/v1/xxxxxx/salesinvoice/SalesInvoices?$filter=InvoiceID eq guid'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx'&$select=InvoiceID
I tried this manually with Postman and also using the existing code from the project.
Is there some setting I am unaware of? Am i querying the wrong way? Maybe there have been some changes to the API I am unaware of that aren't listed in the release notes?
Please provide the request header Accept in your HTTP request that specifies what content format you prefer to receive: application/json. The default of Exact Online APIs is XML (but seldom to never used).
I've started using Apache Nifi and I'm still learning it and experimenting with it. I really want to use Nifi to get JSON documents from API's and put them in my Elasticsearch database. So far using the built-in getTwitter and putElasticsearch controllers this works.
However now I want to do this with other APIs than Twitter, and I'm kinda stuck here. First off I really don't even know which controller to use? I would think getHttp or invokeHttp even with 'GET' as http verb then but it doesn't seem to work. If I use the getHttp I have to give an SSL service with keystore and truststore .. like why would I have to do that?
Apache Nifi is still quite new so hard to find decent guides / information about these kinds of things. I have read and searched the documentation but haven't gotten the wiser.
An example JSON to pick up from an API is:
https://api.ssllabs.com/api/v2/getEndpointData?host=www.bnpparibasfortis.be&s=193.58.4.82
Thanks in advance for anyone that can offer some help / insight.
What processor you use to get the JSON data is entirely dependent on the API you want to hit. The GetHttp or InvokeHttp processors should work to grab the data from a URL. If you'll notice, the SSL service is an optional property for both GetHttp and InvokeHttp so you only need to you use it when you want to communicate via HTTPS. Also, from the UI you can right click on a processor and then click "usage" to bring up the documentation for that processor.
At this link[1] you can find a NiFi template that uses GetHttp to get JSON data from randomuser.me and does various processing on it. It's primarily a template to show-case the different Avro processors but the method of grabbing the JSON should be relevant.

I'm writing a RESTful web application where I need to provide the service of uploading images for a user. Currently, I have been able to upload an image from my current machine but I need to send it as JSON data over the web through the REST protocol.
In the server, there is a Java application running Jax-RS to manage the RESTful service. I was planning to save the JSON data that contains the image in the server and then provide a URL to the user for him to be able to locate it's image on the server.
Can someone provide some ideas on how can I do this?
If you want to send the image in a JSON object, then the image should be Base64 encoded it, or some other form of encoding. Then on the server side you will need to unmarshal the JSON and then decode back the image. You can get some ideas here on how that can be done.
Optionally, instead of doing all the converting inside the resource method (as in the example linked above), you could write a custom MessageBodyReader, where you can do the unmarshalling and decoding there.
If you decide you don't want to work with JSON, you can go the normal route and use Multipart. Depending on the implementation of JAX-RS you are using, multipart support will be different. You can see some examples (all examples have links to the official documentation)
Jersey example
Resteasy example
CXF example
There are other implementations, but I don't have examples for those. You will need to search for the documentation if you're using an implementation other than listed above.
I'm attempting to query an REST service with fairly limited idea of how to approach it.
I'm using Delphi XE6 (upd 1)
The company providing the API have said that: "The API is implemented as JSON via SSL"
and they go on to say that:
Access to any API endpoint requires authentication via signed requests, created with publicand secret API
keys
I have the keys defined above.
The signature is an HMACSHA256 hash of a string containing the request contenttype, host,
URL, date timestamp (matching the request Date header) and request content (eg POST
parameters) separated by a single newline, and passed with the public key in a custom header
XAPIAuthorization along with the public key, in the format PUBLICKEY:SIGNATURE
I understand each request needs to be signed.
How do I sign an http request with Delphi XE6?
The confusion for me at the moment is it seems Delphi has a number of built-in components have accessing RSET servers and parsing the JSON returned. I can't see any obvious way of signing requests using these components.
Specifically is there any help from the built-in Rest components or do I have to provide my own solution?

How to create worklight http adapter get json object? Then using json object let it to dojo mobile!
I have ever see a example using jquery link to open data api. But not ever see using dojo mobile link open data.
Yes. Read the Getting Started modules and try the code samples. Specifically I would recommend:
Adapter framework overview
HTTP adapter – Communicating with HTTP back-end systems
Invoking adapter procedures from client applications.
Also take a look at the documentation here. There's an example with Worklight + Dojo Mobile here.
