Easy-to-use RSS client driver enables developers to build Java applications that easily consume RSS feeds.

Access RSS Feeds in Mule Applications Using the CData JDBC Driver



Create a simple Mule Application that uses HTTP and SQL with the CData JDBC Driver for RSS to create a JSON endpoint for RSS feeds.

The CData JDBC Driver for RSS connects RSS feeds 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 RSS feeds.

This article demonstrates how to use the CData JDBC Driver for RSS inside of a Mule project to create a Web interface for RSS feeds. The application created allows you to request RSS feeds 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.rss.jar).
    • Set the URL to the connection string for RSS

      You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.rss.jar

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

    • Set the Driver class name to cdata.jdbc.rss.RSSDriver.
    • Click Test Connection.
  6. Set the SQL Query Text to a SQL query to request RSS feeds. For example: SELECT Pubdate, Author FROM RSSFeed
  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 RSS feeds, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The RSS feeds 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 RSS feeds (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 RSS and see the CData difference in your Mule Applications today.
