Connect to Google Campaign Manager Data from a Connection Pool in Jetty

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

   <Configure id='doubleclickdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="doubleclickdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="doubleclickdemo"/></Arg> <Arg>jdbc/doubleclickdb</Arg> <Arg> <New class="cdata.jdbc.googlecm.GoogleCMDriver"> <Set name="url">jdbc:googlecm:</Set> <Set name="UserProfileID">MyUserProfileID</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   Google Campaign Manager uses the OAuth authentication standard. The data provider facilitates OAuth in various ways as described below. The following OAuth flow requires the authenticating user to interact with DoubleClick Campaign Manager, using the browser. You can also use a service account to authenticate.

   For authentication guides, see the Getting Started section of the data provider help documentation.

4. Configure the resource in the Web.xml:

   jdbc/doubleclickdb javax.sql.DataSource Container

5. You can then access Google Campaign Manager with a lookup to java:comp/env/jdbc/doubleclickdb: InitialContext ctx = new InitialContext(); DataSource mydoubleclick = (DataSource)ctx.lookup("java:comp/env/jdbc/doubleclickdb");
