Getting HTTP Error 503 while accessing JIRA Rest API

[Amandeep Singh]

Hi

I am getting the following exception while connecting to JIRA rest API on line in bold

URL - http://jira.amadeusri.com/rest/api/2/issue/ARI-20092?expand=changelog

Code - 

URL _url = new URL("<JIRA URL>" +"rest/api/2/issue/" + id +"?expand=changelog");
String _json = webRequest.getUrl( _url,"xxxx","xxxx");

getURL method in WebRequest.java

URLConnection _urlConnection = url.openConnection();
_urlConnection.setConnectTimeout(10 * 60 * 1000);
_urlConnection.setReadTimeout(10 * 60 * 1000);

if (username != null && !username.isEmpty()) {
    String _authStringEnc = new String(
            Base64.encodeBase64(
                    (username + ":" + password).getBytes()
            )
    );
    System.out.println("Auth: " + _authStringEnc);

    _urlConnection.setRequestProperty("Authorization", "Basic " + _authStringEnc);
    System.out.println(_urlConnection.getContentType());
}

String _ret = IOUtils.toString(_urlConnection.getInputStream());
System.out.println("Returned " + _ret.length() + " chars");

return _ret;

Hi! 

503 - Service Unavailable, does your service work from internet? 

Cheers,

Gonchik Tsymzhitov

Yes, the same rest URL works on browser.

[Gonchik Tsymzhitov]

Well, let's reuse this client

https://bitbucket.org/atlassian/jira-rest-java-client

[Amandeep Singh]

Thanks Gonchik for the information. I implemented the same using the client but I am still getting the same exception.

@Gonchik Tsymzhitov - Can you please help. This is something which I tried -

Installed JIRA trail version on my local. When I try to access that JIRA it works but when I try to access company's JIRA, I get an Error 503. Another observation - JIRA client on my local using HTTP while the organisation using HTTPS. 

Really looking forward to your response.
