Exact Online JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Exact Online account data including Contacts, Opportunities, Accounts, and more!



Connect to Exact Online 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 Exact Online data from a connection pool in Tomcat.

Connect to Exact Online 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.

    Exact Online uses the OAuth authentication standard. The InitiateOAuth connection property facilitates the OAuth flow -- by default, this is set to GETANDREFRESH. You can also use the embedded OAuth credentials or you can register an OAuth app with Exact to obtain your own. In addition to the OAuth values, provide the Region. If Division is not set, the default Division is determined.

    See the "Getting Started" chapter of the help documentation for more information.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.exactonline.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/exactonline" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.exactonline.ExactOnlineDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:exactonline:Region='United States';Division=5512;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Exact Online 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 Exact Online for all applications.

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