Connect to ADP Data from a Connection Pool in Jetty

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

   <Configure id='adpdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="adpdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="adpdemo"/></Arg>
    <Arg>jdbc/adpdb</Arg>
    <Arg>
    <New class="cdata.jdbc.adp.ADPDriver">
    <Set name="url">jdbc:adp:</Set>
    <Set name="OAuthClientId">YourClientId</Set>
    <Set name="OAuthClientSecret">YourClientSecret</Set>
    <Set name="SSLClientCert">'c:\cert.pfx'</Set>
    <Set name="SSLClientCertPassword">'admin@123'</Set>
    <Set name="InitiateOAuth">GETANDREFRESH</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   Connect to ADP by specifying the following properties:

   • OAuthClientId: The client Id of the custom OAuth application you obtained from ADP.
   • OAuthClientSecret: The custom OAuth application's client secret.
   • SSLClientCert: Set this to the certificate provided during registration.
   • SSLClientCertPassword: Set this to the password of the certificate.
   • UseUAT: The connector makes requests to the production environment by default. If using a developer account, set UseUAT = true.
   • RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table. The default value will be set to 100. Setting a high value may decrease performance.

   The connector uses OAuth to authenticate with ADP. OAuth requires the authenticating user to interact with ADP using the browser. OAuth access can be configured in ADP through ADP API Central. For more information, refer ADP's API Central Quick Start Guide and the OAuth section in CData's Help documentation.

4. Configure the resource in the Web.xml:

    jdbc/adpdb
    javax.sql.DataSource
    Container
   
   

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

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