Connect to Paddle Data from a Connection Pool in Jetty

The CData JDBC driver for Paddle is easy to integrate with Java Web applications. This article shows how to efficiently connect to Paddle data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Paddle in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

   java -jar ../start.jar --add-to-startd=jndi
   

2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.

3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Paddle data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   
   <Configure id='paddledemo' class="org.eclipse.jetty.webapp.WebAppContext">
       <New id="paddledemo" class="org.eclipse.jetty.plus.jndi.Resource">
       <Arg><Ref refid="paddledemo"/></Arg>
       <Arg>jdbc/paddledb</Arg>
       <Arg>
         <New class="cdata.jdbc.api.APIDriver">
           <Set name="url">jdbc:api:</Set>
           <Set name="Profile">C:\profiles\Paddle.apip</Set>
           <Set name="AuthScheme">APIKey</Set>
           <Set name="ProfileSettings">"APIKey</Set>
         </New>
       </Arg>
     </New>
   </Configure>
   

   Using API Key Authentication

   Paddle uses API key authentication. To obtain an API key:

   1. Sign in to your Paddle account at https://vendors.paddle.com
   2. Navigate to Developer Tools > Authentication
   3. Click "Generate API Key"
   4. Assign the appropriate permissions for the data you wish to access
   5. Copy the generated key (sandbox keys begin with pdl_sdbx_apikey_; production keys begin with pdl_live_apikey_)

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your Paddle API key.

   Example Connection String

   Profile=C:\profiles\Paddle.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";
   

   Connecting to Paddle

   Once the authentication is configured, you can connect to Paddle and query data from any of the available tables such as Products, Customers, Subscriptions, and Transactions.

4. Configure the resource in the Web.xml:

   
     jdbc/paddledb
     javax.sql.DataSource
     Container
   
   

5. You can then access Paddle with a lookup to java:comp/env/jdbc/paddledb:

   InitialContext ctx = new InitialContext();
   DataSource mypaddle = (DataSource)ctx.lookup("java:comp/env/jdbc/paddledb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
