Design BIRT Reports on Bitbucket Data

The CData JDBC Driver for Bitbucket integrates connectivity to Bitbucket APIs into your data-driven Java applications. You can use the CData JDBC Driver for Bitbucket with the BIRT (Business Intelligence Reporting Tools) platform to create BIRT reports that reflect changes to your data in real time.

1. If you have not already done so, install the BIRT Framework plugin and the Database Development plugin for Eclipse.
2. Click File -> New -> Report. The Report Design perspective is opened.
3. In the Data Explorer, right-click Data Sources and click New Data Source.
4. Select the Create from a Data Source Type in the Following List option and select JDBC Data Source.
5. Click Manage Drivers and add the driver JAR, located in the lib subfolder of the installation folder.
6. In the Database URL box, enter the JDBC URL containing the connection string.

   For most queries, you must set the Workspace. The only exception to this is the Workspaces table, which does not require this property to be set, as querying it provides a list of workspace slugs that can be used to set Workspace. To query this table, you must set Schema to 'Information' and execute the query SELECT * FROM Workspaces>.

   Setting Schema to 'Information' displays general information. To connect to Bitbucket, set these parameters:

   • Schema: To show general information about a workspace, such as its users, repositories, and projects, set this to Information. Otherwise, set this to the schema of the repository or project you are querying. To get a full set of available schemas, query the sys_schemas table.
   • Workspace: Required if you are not querying the Workspaces table. This property is not required for querying the Workspaces table, as that query only returns a list of workspace slugs that can be used to set Workspace.

   Authenticating to Bitbucket

   Bitbucket supports OAuth authentication only. To enable this authentication from all OAuth flows, you must create a custom OAuth application, and set AuthScheme to OAuth.

   Be sure to review the Help documentation for the required connection properties for you specific authentication needs (desktop applications, web applications, and headless machines).

   Creating a custom OAuth application

   From your Bitbucket account:

   1. Go to Settings (the gear icon) and select Workspace Settings.
   2. In the Apps and Features section, select OAuth Consumers.
   3. Click Add Consumer.
   4. Enter a name and description for your custom application.
   5. Set the callback URL:
      • For desktop applications and headless machines, use http://localhost:33333 or another port number of your choice. The URI you set here becomes the CallbackURL property.
      • For web applications, set the callback URL to a trusted redirect URL. This URL is the web location the user returns to with the token that verifies that your application has been granted access.
   6. If you plan to use client credentials to authenticate, you must select This is a private consumer. In the driver, you must set AuthScheme to client.
   7. Select which permissions to give your OAuth application. These determine what data you can read and write with it.
   8. To save the new custom application, click Save.
   9. After the application has been saved, you can select it to view its settings. The application's Key and Secret are displayed. Record these for future use. You will use the Key to set the OAuthClientId and the Secret to set the OAuthClientSecret.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Bitbucket JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.bitbucket.jar
   

   Fill in the connection properties and copy the connection string to the clipboard.

   When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

   A typical JDBC URL is below:

   jdbc:bitbucket:Workspace=myworkspaceslug;Schema=Information;InitiateOAuth=GETANDREFRESH;
   

7. Right-click the Data Sets folder and select the JDBC data source for Bitbucket.
8. In the resulting dialog, build the SELECT query to be used to retrieve the data for the report. This article uses the following query:

   SELECT Title, ContentRaw FROM Issues WHERE Id = '1'
   

9. In the Palette, drag a Chart onto the editor. The chart wizard is displayed.
10. After selecting the chart type, drag columns onto the chart fields on the Select Data tab.
11. Click Run -> View Report -> In Web Viewer to view the report.

Your BIRT reports can now pick up any updates to Bitbucket data. 👁 A BIRT report that can be refreshed on demand. (Salesforce is shown.)

To publish the report to your application server, add the driver JAR to the BIRT Viewer's classpath. For more information, see the CData KB for guides to deploying the JDBC Driver on Java application servers.
