Access Confluence Data in Mule Applications Using the CData JDBC Driver

The CData JDBC Driver for Confluence connects Confluence data to Mule applications enabling read functionality with familiar SQL queries. The JDBC Driver allows users to easily create Mule applications to backup, transform, report, and analyze Confluence data.

This article demonstrates how to use the CData JDBC Driver for Confluence inside of a Mule project to create a Web interface for Confluence data. The application created allows you to request Confluence data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData JDBC Driver to create a Web interface for the 200+ available data sources.

1. Create a new Mule Project in Anypoint Studio.
2. Add an HTTP Connector to the Message Flow.
3. Configure the address for the HTTP Connector.
4. Add a Database Select Connector to the same flow, after the HTTP Connector.
5. Create a new Connection (or edit an existing one) and configure the properties.
   • Set Connection to "Generic Connection"
   • Select the CData JDBC Driver JAR file in the Required Libraries section (e.g. cdata.jdbc.confluence.jar).
   • Set the URL to the connection string for Confluence

     Obtaining an API Token

     An API token is necessary for account authentication. To generate one, login to your Atlassian account and navigate to API tokens > Create API token. The generated token will be displayed.

     Connect Using a Confluence Cloud Account

     To connect to a Cloud account, provide the following (Note: Password has been deprecated for connecting to a Cloud Account and is now used only to connect to a Server Instance.):

     • User: The user which will be used to authenticate with the Confluence server.
     • APIToken: The API Token associated with the currently authenticated user.
     • Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.

     Connect Using a Confluence Server Instance

     To connect to a Server instance, provide the following:

     • User: The user which will be used to authenticate with the Confluence instance.
     • Password: The password which will be used to authenticate with the Confluence server.
     • Url: The URL associated with your JIRA endpoint. For example, https://yoursitename.atlassian.net.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.confluence.jar

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

   • Set the Driver class name to cdata.jdbc.confluence.ConfluenceDriver.
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request Confluence data. For example: SELECT Key, Name FROM Pages WHERE Id = '10000'
7. Add a Transform Message Component to the flow.
8. Set the Output script to the following to convert the payload to JSON:

   %dw 2.0
   output application/json
   ---
   payload
           

9. To view your Confluence data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Confluence data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with Confluence data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools. Download a free, 30 day trial of the JDBC Driver for Confluence and see the CData difference in your Mule Applications today.
