Re: [Dev] [ESB] JSON to SOAP conversion issue
Hi Rajith, Thanks, the error got resolved after using application/xml as messageType. However, I am not getting a SOAP payload as the response as I got earlier. Here are the two responses I got: 1. with JsonBuilder and JsonFormatter HTTP/1.1 200 OK Host: localhost:8283 SOAPAction: Content-Type: text/xml; charset=UTF-8 Accept: */* Date: Sun, 18 Dec 2016 19:15:43 GMT Transfer-Encoding: chunked http://schemas.xmlsoap.org/soap/envelope/";> ** *world* ** 2. with JsonStreamBuilder and JsonStreamFormatter HTTP/1.1 200 OK Host: localhost:8280 SOAPAction: Content-Type: application/xml; charset=UTF-8 Accept: */* Date: Mon, 19 Dec 2016 06:40:36 GMT Transfer-Encoding: chunked ** *world* ** Thanks!

[Dev] Reading config.yaml file from client side
Hi guys,
We are doing the routing from the client side. So we want to read the app
context from javascript. Is there a nice way to do this without adding a
var context = '{{@config.context}}'; ?
It the @config is available in the client side it will be a nice feature
addition to UUF.
thanks,
Chanaka

[Dev] [ESB] JSON to SOAP conversion issue
Hi all, I am seeing error [1] in ESB 5.0.0 and 4.9.0 while checking SOAP <-> JSON conversion via a proxy. I have attached the Proxy and the sample backend API (json) I used. When invoke the proxy using the following curl command I can see the error [1] and client is not getting any response. curl http://localhost:8280/services/Soap2JsonProxy -X POST -H "Content-Type: text/xml" -H 'SOAPAction: "urn:getVersion"' But the error goes away if I used following message builder and formatter for application/json content type. And client gets the converted json to soap payload successfully. Is this a limitation/bug or am I doing something wrong?
