Connect to Reckon Accounts Hosted Data from a Connection Pool in Jetty

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

   <Configure id='reckonaccountshosteddemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="reckonaccountshosteddemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="reckonaccountshosteddemo"/></Arg> <Arg>jdbc/reckonaccountshosteddb</Arg> <Arg> <New class="cdata.jdbc.reckonaccountshosted.ReckonAccountsHostedDriver"> <Set name="url">jdbc:reckonaccountshosted:</Set> <Set name="SubscriptionKey">my_subscription_key</Set> <Set name="CountryVersion">2021.R2.AU</Set> <Set name="CompanyFile">Q:/CompanyName.QBW</Set> <Set name="User">my_user</Set> <Set name="Password">my_password</Set> <Set name="CallbackURL">http://localhost:33333</Set> <Set name="OAuthClientId">my_oauth_client_id</Set> <Set name="OAuthClientSecret">my_oauth_client_secret</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

   • SubscriptionKey: Required. You get this value when you created your developer account.
   • CountryVersion: Defaults to 2021.R2.AU.
   • CompanyFile: Required. The path to the company file.
   • User: Required. The username of the company file.
   • Password: Required. The password of the company file.
   • InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
   • CallbackURL: The redirectURI of your Custom OAuth App.
   • OAuthClientId: The client id of your Custom OAuth App.
   • OAuthClientSecret: The client secret of your Custom OAuth App.

   CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

4. Configure the resource in the Web.xml:

   jdbc/reckonaccountshosteddb javax.sql.DataSource Container

5. You can then access Reckon Accounts Hosted with a lookup to java:comp/env/jdbc/reckonaccountshosteddb: InitialContext ctx = new InitialContext(); DataSource myreckonaccountshosted = (DataSource)ctx.lookup("java:comp/env/jdbc/reckonaccountshosteddb");
