With Jersey Client

ClientResponse response;
 String auth = new String(Base64.encode("username" + ":" + "password"));
 final String headerAuthorization = "Authorization";
 final String headerAuthorizationValue = "Basic " + auth;
 final String headerType = "application/json";
Client client = Client.create();

WebResource webResource = client.resource("url");
response =  webResource.header(headerAuthorization, headerAuthorizationValue).type(headerType).accept(headerType).get(ClientResponse.class);

@Alexey Matveev 

It doesn't work for me :(

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I used this URL:

WebResource webResource = client.resource("https://deljira");

@Kanishk.Kejriwal you can use the Base64 class from these locations:

// From the Jersey Client dependency
import com.sun.jersey.core.util.Base64;
String auth = new String(Base64.encode("username" + ":" + "password"));


// From Java
import java.util.Base64;
import java.nio.charset.StandardCharsets;

How to do it with OAUTH2.0 

as you are using  basic auth here for authentication

[Nhac Tat Nguyen]

For OAuth, see this link: https://developer.atlassian.com/server/jira/platform/oauth/

I am asking for JIRA software 

the way to do OAUTH2.0 authentication call is here: https://developer.atlassian.com/cloud/jira/platform/oauth-2-3lo-apps/

from this document I got to know how to authenticate using OAUTH2.0 But the thing is I have to put the Authorization code URI in Browser to get the auth code you can refer to this

video: https://www.youtube.com/watch?v=ayiGEctaky0&t=4s

timestamp: 2:48 onwards

then after that I can make the access token request with the help of that AUTH code

but what I want to know is , how can I do this AUTHORIZATION CALL  thing in POSTMAN

How can i do the Authorization call inside postman?????
