TaxJar JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with TaxJar.



Write standard ColdFusion data access code to connect to TaxJar data.

The CData JDBC Driver for TaxJar seamlessly integrates connectivity to TaxJar data with the rapid development tools in ColdFusion. This article shows how to connect to TaxJar data in ColdFusion and query TaxJar tables.

Create a JDBC Data Source for TaxJar in ColdFusion

The JDBC data source enables you to execute SQL from standard ColdFusion tags like cfquery and CFScript like executeQuery.

  1. Copy the driver JAR and .lic file from the installation directory onto the ColdFusion classpath. For example, copy the files into C:\MyColdFusionDirectory\cfusion\wwwroot\WEB-INF\lib. Or, open the Java and JVM page in the ColdFusion Administrator and enter the path to the files in the ColdFusion Class Path box.

    The JAR and license for the driver are located in the lib subfolder of the installation directory.

    Restart the server after this step.

  2. Add the driver as a data source:

    From the ColdFusion administrator interface, expand the Data & Services node and click Data Sources. In the Add New Data Source section, enter a name for the data source and select Other in the Driver menu.

  3. Populate the driver properties:

    • JDBC URL: Enter connection properties in the JDBC URL. The JDBC URL begins with jdbc:taxjar: and is followed by the connection properties in a semicolon-separated list of name=value pairs.

      To authenticate to the TaxJar API, you will need to first obtain the API Key from the TaxJar UI.

      NOTE: the API is available only for Professional and Premium TaxJar plans.

      If you already have a Professional or Premium plan you can find the API Key by logging in the TaxJar UI and navigating to Account -> TaxJar API. After obtaining the API Key, you can set it in the APIKey connection property.

      Additional Notes

      • By default, the CData connector will retrieve data of the last 3 months in cases where the entity support date range filtering. You can set StartDate to specify the minimum creation date of the data retrieved.
      • If the API Key has been created for a sandbox API account please set UseSandbox to true, but not all endpoints will work as expected. For more information, refer to the TaxJar developer documentation.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.taxjar.jar

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

      A typical JDBC URL is below:

      jdbc:taxjar:APIKey=3bb04218ef8t80efdf1739abf7257144;
    • Driver Class: Enter the driver class. The driver class is cdata.jdbc.taxjar.TaxJarDriver.
    • Driver Name: Enter a user-defined name for the driver.
    • Username: Enter the username used to authenticate.
    • Password: Enter the password used to authenticate.

You can now test the connection by enabling the CData TaxJar data source in the Actions column. After reporting a status of OK, the TaxJar data source is ready for use.

Execute Queries

The cfquery tag can pass SQL statements to TaxJar, including INSERT, UPDATE, and DELETE.. Use the cfqueryparam tag to create parameterized queries and prevent SQL injection through the query string.

<cfquery name="TaxJarQuery" dataSource="CDataTaxJar"> SELECT * FROM Orders WHERE TransactionID = <cfqueryparam value="#TransactionID#" cfsqltype="cf_sql_varchar"> </cfquery> <cfdump var="#TaxJarQuery#">

Below is the equivalent in CFScript:


<cfscript>
result = queryExecute(
  "SELECT * FROM Orders WHERE TransactionID = ?", 
  [
    { value="123", cfsqltype="cf_sql_varchar" }
  ],
  { datasource="CDataTaxJar" }
);

writeDump( var= result );
</cfscript> 

You can then make requests to your .cfm like the following:

http://MyServer:8500/query.cfm?TransactionID=123
