JNDI Datasource Examples

Pooling DataSources
Non-pooling DataSources

Here are examples of configuring a JNDI datasource for various databases.

Note

Read Configuring DataSources in Configuring JNDI for more information about configuring datasources.

All of these examples 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.

Important

You must 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

Pooling datasources enables connection pooling, which 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 BoneCP Download. All configuration options for BoneCP are described here: BoneCP API.
