i was trying to call a .net webservice with the Android SDK, that was simple using the ksoap2 library, including passing and getting complex types.yet i faced a more complicated problem, the
SoapSerializationEnvelope.getResult()
or SoapSerializationEnvelope.getResponse() only gives the return value of the web method, but when there is out parameters in the method, how can i get them?
i found a work arround to get them by setting the AndroidHttpTransport.debug=true and thus being able to get AndroidHttpTransport.responseDump and then parsing this xml string and get the values out of it the thing is that isn't there any simpler way to get these out parameters?
excuse me for the bad formatted question, but this is my first time using it:S..
Thanks in advance
See my answer to How to retrieve binary data from Web Service in Android?
It shown how to access the response parameters.

I am trying to use the REST API of vSphere to get information about our virtual machines. I already connected to the server using the provided REST API and
I got a JSON Result from a REST request. The vSphere JSON result looks like this:
{"value":[{
"hot_add_increment_size_MiB": 8,
"size_MiB": 1,
"hot_add_enabled": false,
"hot_add_limit_MiB": 51258
}]
}
Now I want to convert this JSON String to an appropriate Class.
The problem, I am actually facing is, that it can be a very complex JSON result.
My question is: Is there an API from VMWare, I can use to solve my problem?
Every hint is appreciated.
Many thanks in advance.
The answer is no. There is schema published by VMware. It might not exist.
You may be able to get what you want with this API (disclaimer: I am the author):
https://github.com/DoubleCloudInc/vim-rest-api/
The schema is the same as vSphere API, so you can use the vijava data objects as your Java objects. http://vijava.sf.net. Again, I am the author.
I have an API that returns a list of ~30,000 SKUs. I then need to insert each SKU into the query parameter URL of another API to validate the response of this second API.
I know that something like this is possible with Jmeter where you could possibly do this via a CSV file. How can I accomplish this via REST Assured? An example/sample would be greatly appreciated!
Similar question also applies to using outputs from an API to use as input in body content...
Thanks.
Short answer.You can't as it comes to query parameters. You can have no more than 2000 characters in your URL. Explanation here : What is the maximum length of a URL in different browsers?
With respect of POST method you don't have constraints.
If you are open to evaluating alternatives to REST-assured, Karate allows you to easily achieve such a data-driven test and it is based on Cucumber as well.

In the demos you will find a number of examples that use dynamic JSON data to drive a loop making an HTTP call. Yes, you can dynamically use the data in HTTP responses also in future steps.
Firstly , this is a java program but not Android.
I write a very simple API to get the DB data in Php like below code:
<?php
$query = "Select * from staff order by staff_name";
$reuslt = $mysqli->query($query);
echo json_encode($reuslt->fetch_object());
Suppose that i can get the JSON object in the following URL easily in Android or Php:
http://localhost/Testing/simpleWebService.php
But how can i get it in Java??
I have searched it in Google but the result seems not what i actually want and useful to me
(Reason is i am quite Junior to Java ,Lack of knowledge in Web Service, not accurate keywords inputted........).
I found sth like Jersey, JAX-RS but i don't think this help and the way to get the JSON from the Web Service is complex like that.
Can anyone help ? Thank you very much!!!!!!
The crux of the matter is that you have to replace the behaviour implemented by PHP's json_encode function in Java ie. you have got to find a way to convert the recordset representation of your data to JSON.
1 approach would be to manually convert your recordset to a collection of POJO's then use Jackson to generate the JSON.
However, there are loads of frameworks that make this easier for you to achieve.
What Java framework are you using as that will constrain your future decisions to some degree? How are you reading from your DB - using JDBC API or using an ORM or other library?
There's a lot of info out there for a newbie like myself when it comes to webservices, I acknowledge that.
However, most of the Google results I've seen tend to be focusing on a specific format or strategy, and all of them different to each other.
As a newbie, I am looking to get more of an overview of the various options open to me, their pros & cons... before I start committing to a specific one.
For example, I have an existing webservice created from a SQL Server source via ASP.net and this by default comes out as a DiffGram. So there are articles that tell me how to parse the diffgram data coming into my Android app, but I still do not know if the diffgram is the best option I should be using in the first place.
Should I, for example be changing my webservice to output JSON ?
Does anyone know of a 101 level tutorial or explanation out there ?
Many Thanks
DiffGram is just another type of XML format. In order to parse the XML data in Android, simply use the XMLFullParse class.
FYI: http://developer.android.com/training/basics/network-ops/xml.html
However if you just want to create a simple data exchange WebService, Json is definitely a better choice. Json is simple, lightweight, easier-to-parse and surely easier to use.
Example:
JsonObject json = new JsonObject(jsonString);
json.put("name", "Michael");
json.put("age", "18");
String name = json.opt("name");
I want to read a JSON list from a webservice with Java. The webservice returns a list of authors from luxemburg, e.g. sorted by the year. That's the web-site:
http://www.autorenlexikon.lu/page/periods/1919-1945/1/1/DEU/index.html
So far, I know that I can receive a JSON document with a request like this:
http://www.autorenlexikon.lu/mmp/json.document_list/DEU/0?search_since=1919&search_until=1945
But I only get the first 20 entries. How can I get the next 20 entries? I think the solution is in the JavaScript-code of the web-site, but I am pretty new in JavaScript (also in JSON).
EDIT:
There isn't any official API.
I have already tried:
http://www.autorenlexikon.lu/mmp/json.document_list/DEU/0?pageSize=1000&search_since=1919&search_until=1945
http://www.autorenlexikon.lu/mmp/json.document_list/DEU/0?page_Size=1000&search_since=1919&search_until=1945
...and many more. Who does the JavaScript-code receive all entries? Couldn't I copy this mechanism?
You should check their API and look for a parameter that let's you define the page or the range of results you want to get.
Edit Seems like you'd have to make a POST request and add the start index as well as the page size as post parameters. For more information see #matthijs koevoets' answer.
It depends on how the Webservice has been coded. Nothing to do with JSON specifically. From the results you can see it says
"pageSize":20,
You just have to figure out how to call the Web service with a page size. It may not allow you to query it with a different page size. That's up to the Web service API coded by their developers
their service seems to accept POST parameters only: sort=year&dir=asc&startIndex=0&results=100
