Simulate form post using http client in Android app?

So, I'm currently developing an app for a service which has a json-based (unfortunately) read only API. Retrieving content is no problem at all, however the only way to post content is using a form on their site which location is a PHP script. The service is open source so I know which fields the form expects, but whatever I send, it always results in a BAD REQUEST.
I captured the network traffic inside my browser and as far as I can see, the browser constructs a multipart form request, however when I copy the request and invoke it again using a REST client, a BAD REQUEST gets returned.
Is there a way to construct a http request in Android that simulates a form post?

If it's readonly I think you wouldn't be able to make requests with POST (it's assume for editing or adding things).
If you let me make you an advise, I recommend you using this project as a Library.
https://github.com/matessoftwaresolutions/AndroidHttpRestService
It makes you easy deal with apis, control network problems etc.
You can find a sample of use there.
You only have to:
Build your URL
Tell the component to execute in POST mode
Build your JSON
As I told you, I don't know even if it will work.
I hope it helps!!!

localhost and AJAX/JQuery

I am very new in AJAX/JQuery. I have problem with following thing. I am hoping to get some information and suggestion on following thing.
I have data real time generated data (eg. xyz) in my localhost server which i have programmed using Java.
My question is
Is it possible to retrieve this data ( i.e. xyz) from localhost server using AJAX/JQuery to JavaScript????
What function does that and how do we do that ?? Plz show me with example..it will be very great help for me

Ajax is something just like common HTTP requests, but it is sent inside your jvascript code and can be moderate with javascript.
Independent of the server side script you have, you can use Ajax to send requests and get responses from that server side application (In server side it can be treated as a simple HTTP reauest).
Finally this is a helpful toturial: W3School Tutorial , and if you are familiar with JQuery or using it in your current project, it is the reference for JQuery Ajax: JQuery.ajax, both with samples.

JSONP or other alternatives?

I a deveveloping a web site that comunicates with a custom made webserver by me in Java. The web site is made in PHP/JavaScript/JQuery running on Apache and i made a simple second webserver in Java to support some designed features by me, and this server runs under another port XXXXX. The problem is, i want to make requests in jQuery to second server the domain is diferent, the page runs on domain and the $.getJSON function calls domain:XXXXX wich is not allowed. I thought user $.getJSONP but im concerning concerned issues. The connections between two points is authed (i was think by passing a token beyond the callback generated by jquery). The two poins are supported by. Is there safe in this case use $.getJSONP or exists other alternatives thinking in browsers support(IE7+ and FF3+).
Sorry for my english :)
Best regards lealoureiro

JSONP should work for your needs, however your other option would be to have a proxy service on your second server that would make the request server side. Your client-side code could then access all the data natively via json instead of jsonp.

A simple java SOAP client

I'm new to web services and I've been breaking my head trying to find a simple java SOAP client program on the Internet.
All I want to do is send a SOAP message and receive back some response.
There is a website which offers free web-services.
http://www.webservicex.net/ws/WSDetails.aspx?WSID=17&CATID=7
You feed in the country name and it gives you the country's ISD code. It's as simple as that.
I want to send the country name to the web service and get back its ISD code using only Javaand without any external jars.

Try SoapUI - it's quite awesome and covers almost all aspects of working w/ web-services..

If you're looking for a tool to test web-services, most people I know use Soap-UI: http://www.soapui.org/

GWT applications and the returned response from the server

I have some GWT application that run on the server.
we are subscripting with some solution that pings this application in a regular interval of time.
The point is, this solution (service) checks the returned response from the server to contain some pre-defined keywords.
But as you know, GWT return plain empty HTML page with the data contained in the .js file.
So, the Ping service will not be able to exmain the pre-defined keywords, Is this statement true??
And if this is ture, cannot we find any workaround solution to solve such problem?
Thanks.

The problem you are facing is related to the crawlabitlity of AJAX applications - Google has some pointers for you :) Generally, you need a headless browser on the server to generate the output you'd normally see in the browser, for example see HtmlUnit.

Only the initial container page and the loader script that it embeds are HTML & JS. Afterwards, you use GWT's RPC mechanism to exchange Java objects with the server, or Ajax (eg. RequestBuilder) to exchange any kind of data with the server. you name it: JSON, XML, plain text, etc.
