Java API GET Request - 500 Internal Server Error

[J]

Hey,

all of my GET requests to JIRA return the Internal Server Error 500.

Backend Java Code:

import io.swagger.annotations.Api;

import java.net.URISyntaxException;
import java.util.ArrayList;

import javax.ejb.Stateless;
import javax.inject.Inject;
import javax.inject.Named;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import PACKAGE_NAME.JiraService;

@Api(tags = { "jira" })
@Named
@Stateless
@Path("jira")
public class AktuelleBugs {

     @Inject
        JiraService JiraService;


    @GET
    @Path("/getAktuelleBugs")
    @Produces(MediaType.APPLICATION_JSON)
    public ArrayList<String> getAktuelleBugs() throws URISyntaxException  {
        return JiraService.getAktuelleBugs();
}
}

/*JiraService.java*/

public ArrayList<String> getAktuelleBugs() throws URISyntaxException{
            JiraRestClientFactory factory = new AsynchronousJiraRestClientFactory();
            URI uri = new URI("https://mycompany.com/jira/");
            JiraRestClient client = factory.createWithBasicHttpAuthentication(uri, "user", "password");
            Promise<SearchResult> searchJql = client.getSearchClient().searchJql(
                    "project=\"System Betrieb\" AND issuetype != epic AND type=bug ORDER BY priority ASC");
            SearchResult searchResult = searchJql.claim();

            Iterable<Issue> issues = searchResult.getIssues();
        
            ArrayList<String> issueList= new ArrayList<String>();
                
            for (Issue issue : issues) {
                issueList.add(issue.getKey());
                issueList.add(issue.getSummary());
                issueList.add(issue.getPriority().getName());
            }
                
            return issueList;
        }

Front End gets JSON (BACKEND_URL = localhost:8080/Application_Name/rest/)

angular.module('Application_Name').controller('aktuelleBugs', 
            function ($scope, $http, $q, BACKEND_URL) {
        'use strict';
    
       
      var deferred = $q.defer();
        
        $http({
            method : "GET",
            url : BACKEND_URL + "jira/getAktuelleBugs"
        }).then(function (response) {
            
            deferred.resolve(response.data);
            
        }, function myError(response) {
            deferred.reject(response);
        });
       
        
      deferred.promise.then(function(bugs){
	...
	...
	.

When starting the server(JBOSS) locally everything works fine.

Hoping that this issue can be solved as soon as possible

So the error is in the AktuelleBugs() method. You could move 'return "hello world"' further down, line by line to determine the actual line of the error, but getting the logs is certainly the smart way to go

[J]

I guess I have to ask for the logs, because none of the things I tried worked.

Just for the record:

    Tried to return String "Hello world" with the class AktuelleBugs()

        REST Client was able to GET the String

    Different locations of the class had no effect

Could be an issue with the Server configuration of the JIRA host?!

[Claudio Kirchhoff]

Darn, those would be really helpful 

Then all I can advise is to try to systematically narrow down the problem:

1. Return a hardcoded response from your REST endpoint and see if the error persists
2. if no, then re-add the call to getAktuelleBugs() and return a hardcoded answer from there
3. and so on, until you find out where exactly the error occurs

If you at least know where the error happens, you might get an idea of the reason

[J]

Unfortunately I dont have access to the logs and thank you .

[Claudio Kirchhoff]

There should be an error message in the logs - can you post it?

On a sidenote: you should use 'jiraService' (lowercase) as a variable name!
