JSON Example with Java + Jersey + Atlassian Stash

This is a sample Java program to read a Git branch information hosted in Atlassian Stash using REST web-services. In this code Jersey Client used to contact Stash. The JSON output is parsed to display branch information.

public class Try1 {
public static void main(String[] args) {
               // Load server and authentication details to Jersey client
ClientConfig clientConfig = new ClientConfig();
HttpAuthenticationFeature feature = HttpAuthenticationFeature.basic("siddesh", "*****");
clientConfig.register(feature);
Client client = ClientBuilder.newClient(clientConfig);
WebTarget webTarget = client.target("https://mycompany/stash/rest")
.path("api/1.0/projects/MYPROJ/repos/MYREPO/branches").queryParam("filterText", "MYBRANCH");

                // send request to server
Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);

                //parse response
Response response = invocationBuilder.get();
System.out.println(response.getStatus());
System.out.println(response.getStatusInfo());
String myResponse = response.readEntity(String.class);
System.out.println(myResponse);

System.out.println("=============================");
try {
JSONObject jsonObject = new JSONObject(myResponse);
//JSONObject branchName = jsonObject.getJSONArray("values").getJSONObject(0).get(displayId);
System.out.println(jsonObject.getJSONArray("values").getJSONObject(0).get("displayId"));
} catch (JSONException e) {
e.printStackTrace();
}
}
}
