I'm using WST ok with "HTTP" and "TCP" using both "binary:" and "SOAP"
but no luck when I switch to "json:".

The error I get is:

Invalid character at line 1, pos 0: 'N'

I'm using the sample calculator project to test this with.

I think I have made the correct changes to the server and the client
code as follows:

Server:
1. I include server_service_json
2. Register the json format Server_service_RegisterJsonFormat();

Client:
1. I include  json_formatter
2. Change the connection info from "SOAP:" to "json:" thus..
Code: [Select]theProxy :=
wst_CreateInstance_ICalcService('SOAP:','HTTP:',
'http://127.0.0.1:8000/services/ICalcService');becomes..
 Code: [Select] theProxy :=
wst_CreateInstance_ICalcService('json:','HTTP:',
'http://127.0.0.1:8000/services/ICalcService');

Note: This demo has code for handling headers that I have commented
out on both the client and server to simplify things and works ok
using SOAP so I think the problemm is just the json aspect.

See first point in my signature. Attaching the sample project would be
nice too if possible, so others can check.

Solved: WST does work with json but I was missing "/?format=json" from
the URL. The WST sample project "user_client_console" used in
conjunction with WST sample "http_server" shows all the connection
methods supported by WST and got me the solution.
