Getting Started with the CData JDBC Driver for Cloudflare

---

This guide walks you through everything you need to get started with the CData JDBC driver for Cloudflare. You'll learn how to install and license the driver, configure your first connection, and explore next steps for working with Cloudflare data in your Java applications.

Installation & Licensing

Installing the Driver

1. Download the JDBC driver installer from the CData site.
2. Run the installer and follow the installation wizard.
3. The driver will be installed to the following location: C:\Program Files\CData\CData JDBC Driver for Cloudflare 20xx\lib\
4. The JAR file will be named: cdata.jdbc.api.jar

Once installed, you can add the JAR file to your Java project's classpath using your IDE or build tool.

Activating Your License

You should have received your license key via email from the CData Orders Team. The alphanumeric license key should take the following format:

XXXX-XXXX-XXXX-XXXX-XXXX

Windows

On Windows, the primary licensing method is via license file. When you install the JDBC driver, a license file is automatically created and stored with the driver installation. The driver will automatically detect and use this license file when the JAR is loaded in your application.

If you need to manually activate or update your license:

1. Locate the license file in your installation directory.
2. Update the license file with your license key.
3. The driver will automatically use the updated license on the next connection.

macOS/Linux

Navigate to the JAR's installation directory and in the lib folder run the following command: java -jar cdata.jdbc.api.jar --license

Follow the prompts to enter your license key. This will create a license file in the installation directory that the driver will use for licensing validation.

For detailed license file configuration instructions, refer to the Licensing section under the Getting Started sub-page in the help documentation.

Common Licensing Questions

Can I use my license on multiple machines?
Yes, depending on your subscription tier. Check your order confirmation or contact your account representative for details. If you are unsure of who your account representative is, contact [email protected].

I lost my license key. How do I retrieve it?
Email [email protected] with your order number, and we'll resend your license key.

Can I transfer my license to a different machine?
Yes. When transferring the license to a different machine, you will need to submit a License Transfer Request on our site linked below:

https://www.cdata.com/lic/transfer/

After the License Transfer Request is submitted and successfully processed, an activation will be added to your Product Key and you will be able to activate the full license on the other machine. Once this process is finished, the license on the previous machine will be invalid.

When should I use RTK instead of the license file?
Use RTK when deploying to environments where the machine/node ID changes dynamically, such as containers, cloud instances, or when distributing your application to multiple machines.

For additional licensing questions, contact [email protected]. Viewing and upgrading your license can now be done through our self-service portal at portal.cdata.com.

Connection Configuration

Once your driver is installed and licensed, you're ready to configure a connection to Cloudflare. JDBC connections are established using a connection URL (also called a connection string).

Understanding JDBC Connection URLs

JDBC connection URLs for CData drivers follow this pattern:

jdbc:api:Profile=C:\profiles\Cloudflare.apip;ProfileSettings='APIKey=your_api_token;APIEmail=your_email';

Building Your Connection URL

Recommended: Use the Built-in Connection String Designer

The JDBC driver includes a connection string designer tool that helps you build the correct JDBC URL with all required connection properties.

To launch the Connection String Designer:

1. Navigate to the driver installation directory: C:\Program Files\CData\CData JDBC Driver for Cloudflare 20xx\lib\
2. Double-click the JAR file: cdata.jdbc.api.jar
   OR
   Run from the command line: java -jar cdata.jdbc.api.jar
3. The Connection String Designer will open.
4. Fill in your connection properties in the provided fields.
5. Click Test Connection to verify your settings.
6. Copy the generated JDBC URL from the designer.

The Connection String Designer ensures correct syntax and shows all available connection properties for Cloudflare.

Driver Class Name

When configuring the JDBC driver in IDEs (such as IntelliJ IDEA, Eclipse, or DBeaver) or other tools, you will need to specify the driver class name:

cdata.jdbc.api.APIDriver

Configuring Connection Properties

The specific connection properties required depend on your data source.

Start by setting the Profile connection property to the location of the Cloudflare Profile on disk (e.g. C:\profiles\Cloudflare.apip). Next, set the ProfileSettings connection property to the connection string for Cloudflare (see below).

Cloudflare API Profile Settings

Obtain your Global API Key or create an API Token from the Cloudflare dashboard under My Profile > API Tokens.

For complete information on all available connection properties for Cloudflare, refer to the Establishing a Connection section in the help documentation.

---

Testing Your Connection

You can test your connection in several ways:

In the Connection String Designer

Click the Test Connection button after entering your properties. A successful test confirms your credentials and connection settings are correct.

In Your Application

If the application requires you to move the driver JAR to a specific location, do so now and ensure the JAR is included in your application's classpath. Also, ensure that the .lic file is also moved to the same location for licensing validation purposes.

Note: Many JDBC Connected tools, like DBeaver, do not actually send a live request to the provider when using their Test Connection functionality. It only does a surface test, which essentially just checks that the JAR file functions at a base level. When using a JDBC connected tool, the ConnectOnOpen property should be set to True to ensure a valid Test Connection.

If you are working with the JDBC driver in your IDE, you can execute a simple query to verify the connection:

import java.sql.Connection; 
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

String url = "jdbc:api:Profile=C:\profiles\Cloudflare.apip;ProfileSettings='APIKey=your_api_token;APIEmail=your_email';
Connection conn = DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM AccessApplications LIMIT 1");

if (rs.next()) {
    System.out.println("Connection successful!");
}

If you encounter connection errors:

1. Verify that your connection properties are correct using the Connection String Designer.
2. Check that the driver JAR is in your application's classpath.
3. Review the error message for specific guidance.
4. Contact [email protected] with the error details for troubleshooting assistance.

Common Connection Issues

Driver Not Found / ClassNotFoundException

Solution: Ensure the JDBC driver JAR (cdata.jdbc.api.jar) is properly added to your project's classpath. The configuration method varies by IDE and build tool. Refer to your development environment's documentation or contact [email protected] for assistance.

Authentication Errors

Solution: Verify that your credentials are correct and current. Use the Connection String Designer to test your credentials before adding them to your application. For specific authentication requirements for Cloudflare, consult the Establishing a Connection section in the help documentation.

Network Connectivity Issues

Solution: Ensure that your firewall allows outbound connections on the required ports. Contact [email protected] for specific port and firewall requirements for your data source.

Invalid Connection String Format

Solution: Use the Connection String Designer to generate a properly formatted JDBC URL. The designer ensures correct syntax and property names.
