send and receive json to rest API from teiid

Hi Steven/ Ramesh,

We have an REST streaming api, which will excepts JSON as input and returns JSON as output.

@POST
@Consumes(

{MediaType.APPLICATION_JSON})
@Produces({MediaType.APPLICATION_JSON}

)
@Path("/processTEIIDJsonQueryReq")
public Response processTEIIDJsonQueryReq(TEIIDJsonRequest Req) throws Exception{

}

We used existing WSExecutionFactory as translator to send/receive JSON Req as stream.
I am not able to send JSON query as part of request. I followed below references

https://docs.jboss.org/author/display/TEIID/Web+Services+Translator
Here I am not able to create jsonObject, it is expecting DerivedColoumns

https://issues.jboss.org/browse/TEIID-3016

https://developer.jboss.org/thread/253551?start=0&tstart=0
https://developer.jboss.org/message/923210#923210

As some of links you and Ramesh mentioned about TEIID Designer(to see how procedure created), their is also I am not succeeded. invokeHTTP is the method I am using

I am using below codes

Can you please suggest me how I can send JSON object as part of REST API request.Thanks for help.

Thanks,
