Connect to Phoenix Data from a Connection Pool in Jetty

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

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

    <Configure id='phoenixdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="phoenixdemo" class=""> <Arg><Ref refid="phoenixdemo"/></Arg> <Arg>jdbc/phoenixdb</Arg> <Arg> <New class="cdata.jdbc.apachephoenix.ApachePhoenixDriver"> <Set name="url">jdbc:apachephoenix:</Set> <Set name="Server">localhost</Set> <Set name="Port">8765</Set> </New> </Arg> </New> </Configure>

    Connect to Apache Phoenix via the Phoenix Query Server. Set the Server and Port (if different from the default port) properties to connect to Apache Phoenix. The Server property will typically be the host name or IP address of the server hosting Apache Phoenix.

    Authenticating to Apache Phoenix

    By default, no authentication will be used (plain). If authentication is configured for your server, set AuthScheme to NEGOTIATE and set the User and Password properties (if necessary) to authenticate through Kerberos.

  4. Configure the resource in the Web.xml:

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

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.
