I'm a persistence noob, so please be gentle!
I'm using Hibernate as my persistence manager. Here is my persistence.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="
http://java.sun.com/xml/ns/persistence" xmlns:ns2="
http://java.sun.com/xml/ns/persistence/orm" 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="org.jvnet.hyperjaxb3.ejb.tests.po" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/craeConnectionPool</jta-data-source>
<class>org.jvnet.hyperjaxb3.ejb.tests.po.PurchaseOrderType</class>
<class>org.jvnet.hyperjaxb3.ejb.tests.po.Items</class>
<class>org.jvnet.hyperjaxb3.ejb.tests.po.Items$Item</class>
<class>org.jvnet.hyperjaxb3.ejb.tests.po.USAddress</class>
<properties>
<property name="hibernate.hbm2ddl.auto" value="update"/>
</properties>
</persistence-unit>
</persistence>
When I try to deploy my web application which uses it, however, I get Toplink exceptions. Does Hibernate use Toplink Essentials? I don't think it should, right? ;)
nternal Exception: Exception [TOPLINK-7212] (Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007))): oracle.toplink.essentials.exceptions.ValidationException
Exception Description: The attribute [orderDateItem] from the entity class [class org.jvnet.hyperjaxb3.ejb.tests.po.PurchaseOrderType] does not specify a temporal type. A temporal type must be specified for persistent fields or properties of type java.util.Date and java.util.Calendar.
