Access Kintone Data in Mule Applications Using the CData JDBC Driver

The CData JDBC Driver for Kintone connects Kintone 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 Kintone data.

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

     In addition to the authentication values, set the following parameters to connect to and retrieve data from Kintone:

     • Url: The URL of your account.
     • GuestSpaceId: Optional. Set this when using a guest space.

     Authenticating with Kintone

     Kintone supports the following authentication methods.

     Using Password Authentication

     You must set the following to authenticate:

     • User: The username of your account.
     • Password: The password of your account.

     Using Basic Authentication

     If the basic authentication security feature is set on the domain, supply the additional login credentials with BasicAuthUser and BasicAuthPassword. Basic authentication requires these credentials in addition to User and Password.

     Using Client SSL

     Instead of basic authentication, you can specify a client certificate to authenticate. Set SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword. Additionally, set User and Password to your login credentials.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.kintone.jar

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

   • Set the Driver class name to cdata.jdbc.kintone.KintoneDriver.
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request Kintone data. For example: SELECT CreatorName, Text FROM Comments WHERE AppId = '1354841'
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 Kintone data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The Kintone 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 Kintone 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 Kintone and see the CData difference in your Mule Applications today.
