Jetty/Howto/Configure JNDI Datasource
Contents
Introduction
This document provides examples of configuring a JNDI datasource for various databases.
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.
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></Arg> <Arg>jdbc/DSTest</Arg> <Arg> <New class="com.jolbox.bonecp.BoneCPDataSource"> <Set name="driverClass">com.mysql.jdbc.Driver</Set> <Set name="jdbcUrl">jdbc.url</Set> <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></Arg> <Arg>jdbc/DSTest</Arg> <Arg> <New class="com.mchange.v2.c3p0.ComboPooledDataSource"> <Set name="driverClass">org.some.Driver</Set> <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.
<New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg></Arg> <Arg>jdbc/DSTest</Arg> <Arg> <New class="com.atomikos.jdbc.AtomikosDataSourceBean"> <Set name="minPoolSize">2</Set> <Set name="maxPoolSize">50</Set> <Set name="xaDataSourceClassName">com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</Set> <Set name="UniqueResourceName">DSTest</Set> <Get name="xaProperties"> <Call name="setProperty"> <Arg>url</Arg> <Arg>jdbc:mysql://localhost:3306/databasename</Arg> </Call> <Call name="setProperty"> <Arg>user</Arg> <Arg>some_username</Arg> </Call> <Call name="setProperty"> <Arg>password</Arg> <Arg>some_password</Arg> </Call> </Get> </New> </Arg> </New>
Non-pooling DataSources
If you are deploying in a production environment, use the Pooling DataSources instead.
