Configure the CData JDBC Driver for Google Campaign Manager in a Connection Pool in Tomcat

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Google Campaign Manager data from a connection pool in Tomcat.

Connect to Google Campaign Manager Data through a Connection Pool in Tomcat

1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
2. Add a definition of the resource to the context. Specify the JDBC URL here.

   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.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Google Campaign Manager JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.googlecm.jar

   Fill in the connection properties and copy the connection string to the clipboard.

   You can see the JDBC URL specified in the resource definition below.

   <Resource name="jdbc/googlecm" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.googlecm.GoogleCMDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:googlecm:UserProfileID=MyUserProfileID;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Google Campaign Manager data, add the code above to the context.xml in the application's META-INF directory.

   For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Google Campaign Manager for all applications.

3. Add a reference to the resource to the web.xml for the application. Google Campaign Manager data JSP jdbc/GoogleCM javax.sql.DataSource Container
4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/GoogleCM"); Connection conn = ds.getConnection();
