Configure the CData JDBC Driver for AvaTax in a Connection Pool in Tomcat

Connect to AvaTax 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 AvaTax data from a connection pool in Tomcat.

Connect to AvaTax 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.

    The primary method for performing basic authentication is to provide your login credentials, as follows:

    • User: Set this to your username.
    • Password: Set this to your password.

    Optionally, if you are making use of a sandbox environment, set the following:

    • UseSandbox: Set this to true if you are authenticating with a sandbox account.

    Authenticating Using Account Number and License Key

    Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

    • AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
    • LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account adminstrator and navigating to Settings -> Reset License Key.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.avalaraavatax.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/avalaraavatax" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.avalaraavatax.AvalaraAvataxDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:avalaraavatax:User=MyUser;Password=MyPassword;" maxActive="20" maxIdle="10" maxWait="-1" />

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

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