Connect to Amazon Marketplace Data from a Connection Pool in Jetty

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

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

    <Configure id='amazonmarketplacedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="amazonmarketplacedemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="amazonmarketplacedemo"/></Arg> <Arg>jdbc/amazonmarketplacedb</Arg> <Arg> <New class="cdata.jdbc.amazonmarketplace.AmazonMarketplaceDriver"> <Set name="url">jdbc:amazonmarketplace:</Set> <Set name="AWS Access Key Id">myAWSAccessKeyId</Set> <Set name="AWS Secret Key">myAWSSecretKey</Set> <Set name="MWS Auth Token">myMWSAuthToken</Set> <Set name="Seller Id">mySellerId</Set> <Set name="Marketplace">United States</Set> </New> </Arg> </New> </Configure>

    To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

  4. Configure the resource in the Web.xml:

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