How to create a connection identifier to connect to a database using EclipseLink?

Create a file persistence.xml in folder META-INF of your project:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
        <class>com.tcs.model.TransportAgreement</class>
        <class>com.tcs.model.TransportAgreementVersion</class>
        <exclude-unlisted-classes>true</exclude-unlisted-classes>
        <properties>
            <property name="javax.persistence.jdbc.driver" value="oracle.jdbc.OracleDriver" />
            <!-- EclipseLink should NOT create the database schema -->
            <property name="eclipselink.ddl-generation" value="none" />
            <property name="eclipselink.target-database" value="Auto" />
            <property name="eclipselink.target-server" value="none" />
        </properties>

    </persistence-unit>
</persistence>

This file names two classes under control of EclipseLink.
