sending objects to client browser

[Willis C White <wh...@us.ibm.com>]

I want to send a data object to a client (web page) what is the best 
binding to use for this? 

Currently I am using the jsonrpc binding with dojo but I am not sure how 
to move from sending a String to sending a object. Do I change bindings or 
try to represent the data object (stings and integers) as a supported 
type?

In looking at this page: 
http://tuscany.apache.org/sca-java-bindingjsonrpc.html
The JSON-RPC binding utilize the Databinding Framework to provide support 
for the following data transformations :
Primitive Type <==> JSON <==> Primitive Type 
Array of Primitive Type <==> JSON <==> Array of Primitive Type 
Java bean <==> JSON <==> Java bean 
List <==> JSON <==> List 
Map <==> JSON <==> Map 
Set <==> JSON <==> Set 
 
Could one of theses be used to represent a data object.

Hi Willis

If you create POJOs to represent the complex types on your service
interface the jsonrpc binding should be able to marshal/unmarshal
these for you. See [1] for an example service implementation. In this
particular case the POJOs are generated SDOs but can just hand craft
POJOs.
