How to call Restfull webservice using Powerbuilder.Net

Hi All,

I am trying to call a restfull webservice using PB.Net. I have created the proxy and able to see the response arguments in the Powerbuilder. The return type of the restfull webserivice is JSON type.

But when i am trying to call the webservice, i am getting the below error.

'Exception has been thrown by the target of an invocation. '

URL- http://beta.json-generator.com/api/json/get/EJgQoWHrix

My dummy code -

p_rest nvo_rest

nvo_rest = createp_rest

1. restjson.rootItem result

try

result = nvo_rest.GetMessage ()

messagebox('Success','Success')

catch (System.Exception ls_error)

MessageBox('error',ls_error.Message)

endtry

Can anyone help me on this?

Once this is successfull, i need to call this in Pb classic, anyidea how to call this ( by using any wrapper).If anybody have any sample code, please send me.

Thanks all.

Regards
