Access ServiceNow Data in Mule Applications Using the CData JDBC Driver

The CData JDBC Driver for ServiceNow connects ServiceNow 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 ServiceNow data.

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

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.
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.servicenow.jar).
   • Set the URL to the connection string for ServiceNow

     ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

     See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.servicenow.jar

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

   • Set the Driver class name to cdata.jdbc.servicenow.ServiceNowDriver.
   • Click Test Connection.
6. Set the SQL Query Text to a SQL query to request ServiceNow data. For example: SELECT sys_id, priority FROM incident
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 ServiceNow data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default): http://localhost:8081. The ServiceNow 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 ServiceNow 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 ServiceNow and see the CData difference in your Mule Applications today.
