Siebel EAI - JSON Parsing

Hi,

To Give a background we are using Siebel EAI for our Integration Calls to Perform Order & Service Related transactions using below Techniques

1. Using Inbound HTTP Transport - Parse the Incoming XML and Perform CURD Operation

2. Using Inbound Web Services - Dispatcher to Convert the SOAP into XML then Perform the CURD Operation.

Question 1: Does Siebel EAI Supports "J S O N" message ,then Parsing the In Coming Structure to Perform the CURD Operation.(One Option using Java Business Service Ends up in Coding) Does there any Other Way to achieve this?

Question 2: Can we built any Layer above Siebel to Parse the J S O N Message then subsequently pass it to Siebel. Any thoughts on this Approach.
