Can anyone tell me, how can I get this browser authentication window ?
回答1:
This popup is part of the HTTP-Authentication. In order to get it, you need to enable it in your web server. As Wikipedia puts it:
When the server wants the user agent to authenticate itself towards the server, it can send a request for authentication.
This request should be sent using the HTTP 401 Not Authorized response code containing a WWW-Authenticate HTTP header.
The WWW-Authenticate header for basic authentication (used most often) is constructed as following:
WWW-Authenticate: Basicrealm="insert realm"

That type of window pops up when a web server responds to a request by returning an "Unauthorized" (401) status code. You'd have to tell the server to send that type of response in order to trigger the popup.

The authentication you are talking is called Basic Authentication in web based application where browser popup will be used to get user credentials.
Which Java Application Server you are using ?
