Jetty DataSource Examples

DataSource Examples
　　Here are some examples of setting up a DataSource in JNDI for various databases.
　　These examples all correspond to a <resource-ref> in web.xml like:

<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>



　　For convenience, we will assume that all of the datasources are declared at the jvm scope, but you can of course use other scopes, as discussed here.
　　Don't forget that all JNDI resources can be configured in a jetty.xml file or in a WEB-INF/jetty-env.xml file, or a context xml file. More information on that can be found on the page on JNDI.


Pooling DataSources
　　Enables connection pooling.
Connection pooling is basically re-using existing connections instead of creating a new connection to the database.
This would be highly efficient in terms of memory allocation and speed of the request to the database.
In production, this is highly recommended.

Non-pooling DataSources
　　If you're deploying in production environment, use the Pooling DataSources instead.
