Connect to Drift Data from a Connection Pool in Jetty

The CData JDBC driver for Drift is easy to integrate with Java Web applications. This article shows how to efficiently connect to Drift data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Drift 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 Drift data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='driftdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="driftdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="driftdemo"/></Arg>
    <Arg>jdbc/driftdb</Arg>
    <Arg>
    <New class="cdata.jdbc.api.APIDriver">
    <Set name="url">jdbc:api:</Set>
    <Set name="Profile">C:\profiles\Drift.apip</Set>
    <Set name="Authscheme">OAuth</Set>
    <Set name="OAuthClientId">your_client_id</Set>
    <Set name="OAuthClientSecret">your_client_secret</Set>
    <Set name="CallbackUrl">your_callback_url</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

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

   Drift API Profile Settings

   Drift uses OAuth-based authentication.

   You must first register an application here: https://dev.drift.com. Your app will be assigned a client ID and a client secret. Set these in your connection string via the OAuthClientId and OAuthClientSecret properties. More information on setting up an OAuth application can be found at https://devdocs.drift.com/docs/.

   After setting the following options in the ProfileSettings connection property, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • OAuthClientId: Set this to the Client Id that is specified in your app settings.
   • OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
   • CallbackURL: Set this to the Redirect URI you specified in your app settings.
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.

4. Configure the resource in the Web.xml:

    jdbc/driftdb
    javax.sql.DataSource
    Container
   
   

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

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

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.
