Here's how to generate there required files for enabling JSON in your webservice.

#Know where your project files are.
#Grab DBXRay here : ftp://ftp.stureaps.dk/
#Choose the workspace using workspace selector
#select Functions|Generate Struct Packages for project

Now you can write code like the following:

<code lang="vdf">
...

Use StructPkg\Struct_tReview.pkg
Use StructPkg\Struct_tProduct.pkg
Use StructPkg\Struct_tAddProductRequest.pkg

Use Product.wo
Use Structures.pkg

Object oProductJSON is a cWebService
...

Procedure CreateProduct String Request
tAddProductRequest stRequest
tJsonNode stJson

If (StringToDoc(oJsonFunctions, &request, &stJson)) Begin
Send JsonToStruct of oStructHandler_tAddProductRequest stJson (&stRequest)
Function_Return (CreateProduct(oProduct, stRequest))
End
Else Begin
Error 666 "String parameter does not contain a valid JSON object"
End
End_Procedure
</code>

oProduct is a traditional webservice using SOAP.

Now . Given the following structure definitions:

<code lang="vdf">
Struct meta
Boolean success
String msg
End_Struct

Struct tReview
Integer id
Integer productId
String comment
String author
End_Struct

Struct tProduct
Integer id
String name
String company
tReview[] reviews
End_Struct

Struct tAddProductRequest
String token
tProduct product
End_Struct

Struct tGetProductResponse
Meta meta
tProduct product
End_Struct

Struct tRequest
String token
Integer identifier
End_Struct

Struct tResponse
Meta meta
Integer id
End_Struct

</code>

Then you will be able to communicate with ExtJS 4 using the following model definition:

<code lang="javascript">
Ext.regModel('Acme.Product', {
idProperty: 'id',
successProperty: 'meta.success',
fields: [
{name:'id', type:'int'},
{name: "name", type:"string"},
{name: "company", type:"string"}
],
hasMany: {model:'Acme.Review', name: 'reviews', associationKey: 'reviews'}
});

Ext.regModel('Acme.Review', {
idProperty: 'id',
fields: [
'id',
'product_id',
'comment',
'author'
],
belongsTo:'Acme.Product'
});

</code>

You will be able to send tAddProductRequest as JSON from the client side as the request parameter

How to create VDF Web Applications

2011-04-15T12:12:05Z

Jka: /* In the trenches */

= Introduction =

This page describes the technologies available to create web applictions using Visual DataFlex.

= Getting started =

To be able to develop ASP pages , then you need [http://en.wikipedia.org/wiki/Internet_Information_Services Internet Information Server]. The most easy way to get that these days is to grab Microsofts Web Platform installer here :

http://www.microsoft.com/web/channel/products/WebPlatformInstaller.aspx

This tool will provide you with a full stack for developing asp related things. It will also keep track of certain things you need to enable on Windows Vista and Windows Server 2008.

You will also need to install [[Webapp server]] from the [[Portal:Visual DataFlex]] installer. Note that you will need version 14.1 to support the windows 2008 server.

== Putting on your [http://www.professorsolomon.com/thinkingcap.html Thinking cap]==

Grab your [[DataDictionary|Data Dictionaries]] from your old application and expose these using Web Objects .

*WBO
*Global.asa (this is where your code is stackup up. check the list of WBP's there)

= In the trenches =

*[[EnablingJSONIN]]

== Validation ==
Here are some good links for validating :
*[[HTML]] ( validate here: [http://validator.w3.org/] )
*[[CSS|Cascading Style Sheets]] ( validate here: http://jigsaw.w3.org/css-validator/ )
*[[Javascript]] ( validate here: http://www.jslint.com/ )

== Styling using css ==

Using css for styling can help you if you don't like doing design yourself! If you style using css then somebody else can do the design for you.

*start your adventure here: [http://www.w3.org/Style/CSS/ css]
*go here when something goes wrong: [http://www.quirksmode.org/css/contents.html quirksmode css]

== Javascript on the client ==
[[Javascript]] can be good for validating what the user enters on the screen. It can also be good for fancy [[AJAX]] techniques.
