Consume Jira Service Management OData Feeds in PowerBuilder
This article demonstrates how to consume Jira Service Management data as OData feeds from PowerBuilder using the API Server.
The CData API Server produces secure feeds of Jira Service Management data that you can consume in PowerBuilder DataWindows. The API Server supports the major Web services, including OData, Atom, JSON, HTML, CSV, TSV, and RSS. It also supports the major authentication schemes and SSL.
This article shows how to create a DataWindow that uses the CData API Server to execute reads and writes.
Set Up the API Server
Follow the steps below to begin producing secure Jira Service Management OData services:
Deploy
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
Connect to Jira Service Management
After you deploy the API Server, provide authentication values and other connection properties needed to connect to Jira Service Management by clicking Settings -> Connections and adding a new connection in the API Server administration console.
You can establish a connection to any Jira Service Desk Cloud account or Server instance.
Connecting with a Cloud Account
To connect to a Cloud account, you'll first need to retrieve an APIToken. To generate one, log in to your Atlassian account and navigate to API tokens > Create API token. The generated token will be displayed.
Supply the following to connect to data:
- User: Set this to the username of the authenticating user.
- APIToken: Set this to the API token found previously.
Connecting with a Service Account
To authenticate with a service account, supply the following connection properties:
- User: Set this to the username of the authenticating user.
- Password: Set this to the password of the authenticating user.
- URL: Set this to the URL associated with your JIRA Service Desk endpoint. For example, https://yoursitename.atlassian.net.
Note: Password has been deprecated for connecting to a Cloud Account and is now used only to connect to a Server Instance.
Accessing Custom Fields
By default, the connector only surfaces system fields. To access the custom fields for Issues, set IncludeCustomFields.
You can then choose the Jira Service Management entities you want to allow the API Server access to by clicking Settings -> Resources.
Additionally, click Settings -> Server and change the following settings for compatibility with PowerBuilder:
- Default Format: Select XML (Atom) in the menu.
- Default Version: Select 2.0 in the menu.
Authorize API Server Users
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.
Create a Profile for Jira Service Management
Follow the steps below to use the Database Painter tool to create a database profile for the OData API of the API Server. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.
- Click Tools -> Database Painter.
- Right-click the OData node and click New Profile.
- In the Database Profile Setup dialog, enter the following:
- Profile Name: Enter a user-friendly name for the profile.
- URI: Enter the URL to the OData endpoint of the API Server. This URL will resemble the one below:
http://MyServer:8080/api.rsc - Supply User Id and Password: Click this option to use HTTP Basic authentication. Note that the API Server also supports Windows authentication.
- User Id: Enter the name of an user in the API Server.
- Password: Enter the authtoken of an user in the API Server.
- To view and modify a table, right-click a table and then click Edit Data -> Grid.
Using Jira Service Management Data with PowerBuilder Controls
You can use standard PowerBuilder objects to connect to OData feeds and execute queries. The following example shows how to retrieve Jira Service Management data into a DataWindow.
You can add the following code to the open method:
SQLCA.DBMS = "ODT"
SQLCA.DBParm = "ConnectString='URI=http://MyServer:8080/api.rsc;UID=MyAPIUser;PWD=MyAuthtoken'";
CONNECT USING SQLCA;
dw_requests.SetTransObject(SQLCA);
dw_requests.Retrieve();
