Configure the CData JDBC Driver for Marketo 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 Marketo data from a connection pool in Tomcat.

Connect to Marketo 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.

   Both the REST and SOAP APIs are supported and can be chosen by using the Schema property.

   For the REST API: The OAuthClientId, OAuthClientSecret, and RESTEndpoint properties, under the OAuth and REST Connection sections, must be set to valid Marketo user credentials.

   For the SOAP API: The UserId, EncryptionKey, and SOAPEndpoint properties, under the SOAP Connection section, must be set to valid Marketo user credentials.

   See the "Getting Started" chapter of the help documentation for a guide to obtaining these values.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.marketo.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/marketo" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.marketo.MarketoDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:marketo:Schema=REST;RESTEndpoint=https://311-IFS-929.mktorest.com/rest;OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Marketo 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 Marketo for all applications.

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