Introduction

This document provides examples of configuring a JNDI datasource for various databases.

Idea.png
Tip:
Read the generic JNDI instructions for background information about configuring datasources.


These examples all correspond to a <resource-ref> in web.xml:

  <resource-ref>
     <description>My DataSource Reference</description>
     <res-ref-name>jdbc/DSTest</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
     <res-auth>Container</res-auth>
  </resource-ref>


These examples assume that all of the datasources are declared at the JVM scope, but you can, of course, use other scopes. You can configure all JNDI resources in a jetty.xml file or in a WEB-INF/jetty-env.xml file, or a context XML file. For more information, see JNDI.

Reminder
Be aware that you have to provide jetty with the libraries necessary to instantiate the datasource you have configured by putting the corresponding jar in jetty_home/lib/ext.


Pooling DataSources

Enables connection pooling. Connection pooling lets you reuse an existing connection instead of creating a new connection to the database.This is highly efficient in terms of memory allocation and speed of the request to the database. We highly recommend this option for production environments.

BoneCP

Connection pooling, available at http://jolbox.com/index.html?page=http://jolbox.com/download.html All configuration options for BoneCP are described here: http://jolbox.com/bonecp/downloads/site/apidocs/com/jolbox/bonecp/BoneCPDataSource.html

  <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">

     <Arg>jdbc/DSTest</Arg>
     <Arg>

         <Set name="username">jdbc.user</Set>
         <Set name="password">jdbc.pass</Set>
         <Set name="minConnectionsPerPartition">5</Set>
         <Set name="maxConnectionsPerPartition">50</Set>
         <Set name="acquireIncrement">5</Set>
         <Set name="idleConnectionTestPeriod">30</Set>
      </New>
    </Arg>
  </New>

c3p0

Connection pooling, available at http://repo1.maven.org/maven2/c3p0/c3p0/0.9.1.2/c3p0-0.9.1.2.jar

  <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">

     <Arg>jdbc/DSTest</Arg>
     <Arg>
      <New class="com.mchange.v2.c3p0.ComboPooledDataSource">

         <Set name="jdbcUrl">jdbc.url</Set>
         <Set name="user">jdbc.user</Set>
         <Set name="password">jdbc.pass</Set>
      </New>
     </Arg>
    </New>

dbcp

Connection pooling, available at http://repo1.maven.org/maven2/commons-dbcp/commons-dbcp/1.2/commons-dbcp-1.2.jar

  <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">
     <Arg></Arg>
     <Arg>jdbc/DSTest</Arg>
     <Arg>
         <New class="org.apache.commons.dbcp.BasicDataSource">
            <Set name="driverClassName">org.some.Driver</Set>
            <Set name="url">jdbc.url</Set>
            <Set name="username">jdbc.user</Set>
            <Set name="password">jdbc.pass</Set>
            <Set name="validationQuery">SELECT 1</Set>
         </New>
     </Arg>
    </New>

Note: validationQuery is optional, and works together with the testOnBorrow parameter (which defaults to true but has no effect unless validationQuery is specified) to help ensure that old connections are valid when used. See http://commons.apache.org/dbcp/configuration.html

Atomikos 3.3.2+

Connection pooling + XA transactions.
