Connect to Teradata Data from a Connection Pool in Jetty

The CData JDBC driver for Teradata is easy to integrate with Java Web applications. This article shows how to efficiently connect to Teradata data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Teradata in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

   java -jar ../start.jar --add-to-startd=jndi
   

2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.

3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Teradata data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='teradatademo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="teradatademo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="teradatademo"/></Arg>
    <Arg>jdbc/teradatadb</Arg>
    <Arg>
    <New class="cdata.jdbc.teradata.TeradataDriver">
    <Set name="url">jdbc:teradata:</Set>
    <Set name="User">myuser</Set>
    <Set name="Password">mypassword</Set>
    <Set name="Server">localhost</Set>
    <Set name="Database">mydatabase</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   To connect to Teradata, provide authentication information and specify the database server name.

   • User: Set this to the username of a Teradata user.
   • Password: Set this to the password of the Teradata user.
   • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
   • Port: Specify the port the server is running on.
   • Database: Specify the database name. If not specified, the default database is used.

4. Configure the resource in the Web.xml:

    jdbc/teradatadb
    javax.sql.DataSource
    Container
   
   

5. You can then access Teradata with a lookup to java:comp/env/jdbc/teradatadb:

   InitialContext ctx = new InitialContext();
   DataSource myteradata = (DataSource)ctx.lookup("java:comp/env/jdbc/teradatadb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
