URL Services Data Control (REST / JSON)

Question

Hi,
I am planning to write a PoC of an integration for JIRA in an ADF Application. I am not too expert on REST services but that is what JIRA API gives me, REST API.
I have been trying to create an URL Services Data Control but I have encounter 2 problems;
- Since I need to use 11g R1 I can't choose the HTTP type request so I just have read access through GET request. If I am not mistaken, 11g R2 allows you the possibility to chose GET,POST,DELETE etc.
- Under the assumption that OK, I am OK just working with GET action, the REST service response comes as JSON so I don't know exactly if its worth to use the URL Data Control at this point since once I have created my DC it doesnt have any structure like would normally do.
My questions;
In this blog by Frank Nimphius https://blogs.oracle.com/jdevotnharvest/entry/which_option_to_choose_for he says
Note: In the above, I exclude REST services in my recommendation because this is what ADF will
address much better using the URL data control in JDeveloper 11g R2 (available) and with improved functionality
in the upcoming Oracle JDeveloper 12c release.*.- Is this valid for XML and JSON responses or just for XML responses?
*.- Do I need to create an XSD file myself in order to get a better DC objects?
*.- Finally, what is the best approach since I am confused about all information on internet.
Thanks
p.s: I am using 11.1.1.6

If you are stuck on 11.1.1.6 then you can just write simple POJOs that access the REST services and then expose those services as data controls for ADF.
If you can upgrade to 11.1.2.3 then you'll be able to fully leverage the REST data control - the basic steps are here:
