Connect to QuickBooks Online Data from a Connection Pool in Jetty

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

   <Configure id='qbonlinedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="qbonlinedemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="qbonlinedemo"/></Arg> <Arg>jdbc/qbonlinedb</Arg> <Arg> <New class="cdata.jdbc.quickbooksonline.QuickBooksOnlineDriver"> <Set name="url">jdbc:quickbooksonline:</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   QuickBooks Online uses the OAuth authentication standard. OAuth requires the authenticating user to log in through the browser. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Intuit. Additionally, if you want to connect to sandbox data, set UseSandbox to true.

   See the Getting Started chapter of the help documentation for a guide to using OAuth.

4. Configure the resource in the Web.xml:

   jdbc/qbonlinedb javax.sql.DataSource Container

5. You can then access QuickBooks Online with a lookup to java:comp/env/jdbc/qbonlinedb: InitialContext ctx = new InitialContext(); DataSource myqbonline = (DataSource)ctx.lookup("java:comp/env/jdbc/qbonlinedb");
