Access MongoDB Data in Mule Applications Using the CData JDBC Driver

Create a simple Mule Application that uses HTTP and SQL with CData JDBC drivers to create a JSON endpoint for MongoDB data.

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

This article demonstrates how to use the CData JDBC Driver for MongoDB inside of a Mule project to create a Web interface for MongoDB data. The application created allows you to request MongoDB 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 hundreds of available data sources.

About MongoDB Data Integration

Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:

MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

For more details on MongoDB use case and how CData enhances your MongoDB experience, check out our blog post: The Top 10 Real-World MongoDB Use Cases You Should Know in 2024.


Getting Started


  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. 👁 Add and Configure 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.mongodb.jar). 👁 Adding the JAR file (Salesforce is shown).
    • Set the URL to the connection string for MongoDB

      Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

      Built-in Connection String Designer

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

      		java -jar cdata.jdbc.mongodb.jar

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

    • Set the Driver class name to cdata.jdbc.mongodb.MongoDBDriver. 👁 A configured Database Connection (Salesforce is shown).
    • Click Test Connection.
  6. Set the SQL Query Text to a SQL query to request MongoDB data. For example: 
    SELECT borough, cuisine FROM restaurants
    👁 Configure the Select object (Salesforce is Shown)
  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
    👁 Add the Transform Message Component to the Flow
  9. To view your MongoDB data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The MongoDB 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 MongoDB 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 MongoDB and see the CData difference in your Mule Applications today.
