Connect to Factorial Data from a Connection Pool in Jetty

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

   <Configure id='factorialdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="factorialdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="factorialdemo"/></Arg>
    <Arg>jdbc/factorialdb</Arg>
    <Arg>
    <New class="cdata.jdbc.api.APIDriver">
    <Set name="url">jdbc:api:</Set>
    <Set name="Profile">C:\profiles\Factorial.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>
   

   Authentication

   Factorial uses OAuth 2.0 for authentication to connect to your HR data or to allow other users to connect to their data.

   Using OAuth Authentication

   To connect using OAuth, follow these steps:

   1. Navigate to your Factorial admin panel and create a new OAuth application.
   2. Copy the Client ID and Client Secret from your application configuration.
   3. Configure the following connection properties:

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to OAuth.
   • OAuthClientId: Set this to your OAuth Client ID.
   • OAuthClientSecret: Set this to your OAuth Client Secret.
   • Scope: Set this to specify the data access permissions (default: "read write").

4. Configure the resource in the Web.xml:

    jdbc/factorialdb
    javax.sql.DataSource
    Container
   
   

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

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

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.
