Unauthorized Exception in REST Client

[Anonymous]

Hi All,
I'm using Talend ESB 6.3 version & trying to pull the data from HP ALM to MongoDB. 

In the my job, I've started from "tMongoDBConnection --> tRESTClient --> tExtractXMLField --> tXMLMap --> tMongoDBOutput".
In the REST Client component throwing Exception "HTTP 401 Unauthorized"
My Exception is :
Exception in component tRESTClient_1

Hi, it most likely means the target service is expecting a username and password, please set it in tRESTClient

You need to check - what source REST service description, especial authorisation methods
did You test Your REST API call with Postman or similar tools?
