How do I add data source in persistence.xml so that IntelliJ IDEA sees it ?

I have little desktop application (which works as I want it to) that has following persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/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_1_0.xsd">
    <persistence-unit name="reportingPU" transaction-type="RESOURCE_LOCAL">
        <provider>oracle.toplink.essentials.PersistenceProvider</provider>
        <class>com.test.data.Company</class>
        <properties>
            <property name="toplink.jdbc.user" value="SA"/>
            <property name="toplink.jdbc.password" value=""/>
            <property name="toplink.jdbc.url" value="jdbc:hsqldb:file:ReportingDB"/>
            <property name="toplink.jdbc.driver" value="org.hsqldb.jdbcDriver"/>
            <property name="toplink.target-database" value="HSQL"/>
        </properties>
    </persistence-unit>
</persistence>

When I open class Company.java which looks like

@Entity
@Table(name = "COMPANY")
public class Company implements Serializable{

    @Id
    private Long id;
    @Column(name = "NAME")
    private String name;
}

IDEA underscores "COMPANY" and "NAME" saying data source is not defined. And yes, I don't have it in data source column if I open JPA module configuration.

This article says I should add jta-data-source tag to persistence.xml but it doesn't make datasource show up in JPA module configuration view.

I'm confused :(

Go to Tool/Data Sources menu. It will let you add new datasource based on information in properties tag of your persistence.xml . After that you'll be able to select it in JPA module configuration window.
