Connect Java applications with the DynamoDB real-time NoSQL cloud database service. Use Amazon DynamoDB as the big data backend that powers your Java/J2EE applications.

Connect to Amazon DynamoDB Data from a Connection Pool in Jetty

The Amazon DynamoDB JDBC Driver supports connection pooling: This article shows how to connect faster to Amazon DynamoDB data from Web apps in Jetty.

The CData JDBC driver for Amazon DynamoDB is easy to integrate with Java Web applications. This article shows how to efficiently connect to Amazon DynamoDB data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Amazon DynamoDB 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 Amazon DynamoDB data source at the level of the Web app, in WEB-INF\jetty-env.xml.

    <Configure id='dynamodbdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="dynamodbdemo" class=""> <Arg><Ref refid="dynamodbdemo"/></Arg> <Arg>jdbc/dynamodbdb</Arg> <Arg> <New class="cdata.jdbc.amazondynamodb.AmazonDynamoDBDriver"> <Set name="url">jdbc:amazondynamodb:</Set> <Set name="Access Key">xxx</Set> <Set name="Secret Key">xxx</Set> <Set name="Domain"></Set> <Set name="Region">OREGON</Set> </New> </Arg> </New> </Configure>

    The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

  4. Configure the resource in the Web.xml:

    jdbc/dynamodbdb javax.sql.DataSource Container
  5. You can then access Amazon DynamoDB with a lookup to java:comp/env/jdbc/dynamodbdb: InitialContext ctx = new InitialContext(); DataSource mydynamodb = (DataSource)ctx.lookup("java:comp/env/jdbc/dynamodbdb");

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.
