LinkedIn Ads JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with LinkedIn Ads.



Connect to LinkedIn Ads data from 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 LinkedIn Ads data from a connection pool in Tomcat.

Connect to LinkedIn Ads 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.

    LinkedIn Ads uses the OAuth authentication standard. OAuth requires the authenticating user to interact with LinkedIn using the browser. See the OAuth section in the Help documentation for a guide.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.linkedinads.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/linkedinads" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.linkedinads.LinkedInAdsDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:linkedinads:OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access LinkedIn Ads 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 LinkedIn Ads for all applications.

  3. Add a reference to the resource to the web.xml for the application. LinkedIn Ads data JSP jdbc/LinkedInAds 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/LinkedInAds"); Connection conn = ds.getConnection();

The steps above show how to connect to LinkedIn Ads data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
