Connection refused: no further information

[Sohail Anwar]

I am trying to get issue with Jira-rest-java-client API but what I get is Connection refused: no further information error

Here is my code

package com.app;

import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.BasicIssue;
import com.atlassian.jira.rest.client.api.domain.BasicProject;
import com.atlassian.jira.rest.client.api.domain.Issue;
import com.atlassian.jira.rest.client.api.domain.SearchResult;
import com.atlassian.jira.rest.client.internal.ServerVersionConstants;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;
import com.google.common.collect.Lists;

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.util.List;
public class ConnectJira {

    /*
    * Class variables
    * */

    private static URI base_url = URI.create("http://localhost:2990/jira");


    public static void main(String[] args) throws URISyntaxException, IOException {

        System.out.println("\n\nprogram started\n\n");

        parseArgs(args);

        final  AsynchronousJiraRestClientFactory jiraRestClientFactory = new AsynchronousJiraRestClientFactory();
        String username = "myemail@mydomain.com";
        String password = "myPassword";

        try (JiraRestClient jiraRestClient = jiraRestClientFactory.createWithBasicHttpAuthentication(base_url, username, password)) {

            final int buildNumber = jiraRestClient.getMetadataClient().getServerInfo().claim().getBuildNumber();

            if (buildNumber > ServerVersionConstants.BN_JIRA_4_3) {
                final Iterable<BasicProject> projectsList = jiraRestClient.getProjectClient().getAllProjects().claim();

                for (BasicProject basicProject : projectsList) {

                    System.out.println("\nProjects List\n+" + basicProject + "\n\n");
                }

            }
            if (buildNumber >= ServerVersionConstants.BN_JIRA_4_3) {
                final SearchResult searchResult = jiraRestClient.getSearchClient().searchJql("assignee is not EMPTY").claim();
                for (BasicIssue issue : searchResult.getIssues()) {
                    System.out.println("\nIssue ID\n+" + issue.getKey() + "\n\n");

                }
            }

            final Issue issue = jiraRestClient.getIssueClient().getIssue("PSR-18").claim();

            System.out.println("\nIssue\n+" + issue + "\n\n");

        }

        // close connection

    }


    private static void parseArgs(String[] argsArray) throws URISyntaxException {
        final List<String> args = Lists.newArrayList(argsArray);

        if (!args.isEmpty()) {
            base_url = new URI(args.get(0));
        }
    }
}

Hello Sohail,

Thank you for sending over you’re code snippet along with the logs/error message. After reviewing this and the error which is “Caused by: java.lang.RuntimeException: java.net.ConnectException: Connection refused: no further information”, it seems your issue is due to nothing listening at the address you have within your script. The sanitized address you have listed is http://localhost:2990/jira. Something off about this is that it’s listed as HTTP and not HTTPS. Along with this, ensure this address is proper and the port you have specified if the port Jira is currently running on. A simple test would be to access the URL via a browser and ensure the site loads.

Additional information on the Jira ports may be found at Changing JIRA application TCP ports.

I hope this helps to find the cause of the connection error and you’re able to communicate with your Jira instance.

Regards,
Stephen Sifers
