I want to make a post request with user credentials.
My server side is ready and I have tested it using postman. Something just like this: http:/localhost/8080/appname/oauth/token/grant_type=password&username=bill&password=secret.
I want to send this url by clicking on a certain button in my restygwt client, how to send this request to my server side from my restygwt client's button?
