Get the Report →Access xBase 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 xBase data.
The CData JDBC Driver for xBase connects xBase 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 xBase data.
This article demonstrates how to use the CData JDBC Driver for xBase inside of a Mule project to create a Web interface for xBase data. The application created allows you to request xBase 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.
- Create a new Mule Project in Anypoint Studio.
- Add an HTTP Connector to the Message Flow.
- Configure the address for the HTTP Connector.
- Add a Database Select Connector to the same flow, after the HTTP Connector.
- 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.xbase.jar).
- Set the URL to the connection string for xBase
The DataSource property must be set to the name of the folder that contains the .dbf files. Specify the IncludeFiles property to work with xBase table files having extensions that differ from .dbf. Specify multiple extensions in a comma-separated list.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the xBase JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.xbase.jar
Fill in the connection properties and copy the connection string to the clipboard.
- Set the Driver class name to cdata.jdbc.xbase.xBaseDriver.
- Click Test Connection.
- Set the SQL Query Text to a SQL query to request xBase data. For example:
SELECT Company, SUM(Total) FROM Invoices GROUP BY ContactName
- Add a Transform Message Component to the flow.
- Set the Output script to the following to convert the payload to JSON:
%dw 2.0 output application/json --- payload
- To view your xBase data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The xBase 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 xBase 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 xBase and see the CData difference in your Mule Applications today.
