Configure the CData JDBC Driver for Oracle Eloqua in a Connection Pool in Tomcat

Connect to Oracle Eloqua 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 Oracle Eloqua data from a connection pool in Tomcat.

Connect to Oracle Eloqua 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.

    There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

    If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.oracleeloqua.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/oracleeloqua" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.oracleeloqua.OracleEloquaDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:oracleeloqua:User=user;Password=password;Company=CData;" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Oracle Eloqua 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 Oracle Eloqua for all applications.

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