Get the Report →Integrate with TaxJar Data using Apache Camel2
Create a simple Java app that uses Apache Camel routing and the CData JDBC Driver to copy TaxJar data to a JSON file on disk.
Apache Camel is an open source integration framework that allows you to integrate various systems consuming or producing data. When paired with the CData JDBC Driver for TaxJar, you can write Java apps that use Camel routes that integrate with live TaxJar data. This article walks through creating an app in NetBeans that connects, queries, and routes TaxJar data to a JSON file.
With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live TaxJar data. When you issue complex SQL queries to TaxJar, the driver pushes supported SQL operations, like filters and aggregations, directly to TaxJar and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze TaxJar data using native data types.
Creating A New Maven/Java Project
Follow the steps below to create a new Java project and add the appropriate dependencies:
- Open NetBeans and create a new project.
- Select Maven from the categories list and Java Application from the projects list, then click Next.
- Name the project (and adjust any other properties) and click Finish.
- In the source package, create a new Java class (we used App.java for this article) and add the main method to the class.
Adding Project Dependencies
With the project created, we can start adding the dependencies needed to work with live TaxJar data from our App. If you have not already done so, install Maven in your environment, as it is required to add the JAR file for the CData JDBC Driver to your project.
Installing the CData JDBC Driver for TaxJar with Maven
- Download the CData JDBC Driver for TaxJar installer, unzip the package, and run the JAR file to install the driver.
- Use Maven to install the JDBC Driver as a connector.
mvn install:install-file -Dfile="C:\Program Files\CData[product_name] 2019\lib\cdata.jdbc.taxjar.jar" -DgroupId="org.cdata.connectors" -DartifactId="cdata-taxjar-connector" -Dversion="19" -Dpackaging=jar
Once the JDBC Driver is installed, we can add dependencies to our project. To add a dependency, you can either edit the pom.xml file or right-click the dependencies folder and click Add Dependency. The properties for each dependency follow, but you can search through the available libraries by typing the name of the dependency in the Query box in the Add Dependency wizard.
Required Dependencies
Dependency | Group ID | Artifact ID | Version |
---|---|---|---|
camel-core | org.apache.camel | camel-core | 3.0.0 |
camel-jackson | org.apache.camel | camel-jackson | 3.0.0 |
camel-jdbc | org.apache.camel | camel-jdbc | 3.0.0 |
camel-jsonpath | org.apache.camel | camel-jsonpath | 3.0.0 |
cdata-taxjar-connector | org.cdata.connectors | cdata-salesforce-connector | 19 |
commons-dbcp2 | org.apache.commons | commons-dbcp2 | 2.7.0 |
slf4j-log4j12 | org.slf4j | slf4j-log4j12 | 1.7.30 |
log4j | org.apache.logging.log4j | log4j | 2.12.1 |
Accessing TaxJar Data in Java Apps with Camel
After adding the required dependencies, we can use the Java DSL (Domain Specific Language) to create routes with access to live TaxJar data. Code snippets follow. Download the sample project (zip file) to follow along (make note of the TODO comments).
Start by importing the necessary classes into our main class.
import org.apache.camel.CamelContext; import org.apache.camel.builder.RouteBuilder; import org.apache.camel.impl.DefaultCamelContext; import org.apache.camel.support.SimpleRegistry; import org.apache.commons.dbcp2.BasicDataSource; import org.apache.log4j.BasicConfigurator;
Then in the main method, we configure logging, create a new BasicDataSource and add it to the registry, create a new CamelContext, and finally add a route to the context. In this sample, we route TaxJar data to a JSON file.
Configure Logging
BasicConfigurator.configure();
Create a BasicDataSource
Create a BasicDataSource and set the driver class name (cdata.jdbc.salesforce.SalesforceDriver) and URL (using the required connection properties).
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.
BasicDataSource basic = new BasicDataSource(); basic.setDriverClassName("cdata.jdbc.taxjar.TaxJarDriver"); basic.setUrl("jdbc:taxjar:APIKey=3bb04218ef8t80efdf1739abf7257144;");
The CData JDBC Driver includes a built-in connection string designer to help you configure the connection URL.
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.
Add the BasicDataSource to the Registry and Create a CamelContext
SimpleRegistry reg = new SimpleRegistry(); reg.bind("myDataSource", basic); CamelContext context = new DefaultCamelContext(reg);
Add Routing to the CamelContext
The routing below uses a timer component to run one time and passes a SQL query to the JDBC Driver. The results are marshaled as JSON (and formatted for pretty print) and passed to a file component to write to disk as a JSON file.
context.addRoutes(new RouteBuilder() { @Override public void configure() { from("timer://foo?repeatCount=1") .setBody(constant("SELECT * FROM Account LIMIT 10")) .to("jdbc:myDataSource") .marshal().json(true) .to("file:C:\\Users\\USER\\Documents?fileName=account.json"); } });
Managing the CamelContext Lifecycle
With the route defined, start the CamelContext to begin the lifecycle. In this example, we wait 10 seconds and then shut down the context.
context.start(); Thread.sleep(10000); context.stop();
