JBoss5.0.0.CR1 and EJB3 persistence

[jc7442]

I use EJB3 persistent entities with JBoss 5.0.0.CR1.

My persistence.xml looks like:

<persistence-unit name="audittrail">
 <jta-data-source>java:/DemoDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop" />
 </properties>
 <!-- ../ is a workaround for http://jira.jboss.com/jira/browse/EJBTHREE-724 -->
 <!--jar-file>../demo-1.0-SNAPSHOT.jar</jar-file-->
 <jar-file>file:/D:/demo/demo.ear/demo-1.0-SNAPSHOT.jar</jar-file>

 </persistence-unit>

My jar is included in an ear. When i try to deploy my ear in JBoss5.0.0.CR1, I have:

vfsfile:... -> org.xml.sax.SAXException
: cvc-complex-type.2.4.d: Invalid content was found starting with element 'jar-file'. No child element is expected at this point. @ vfsfile:/.../META-INF/pe
rsistence.xml[17,13]


I looks like jar-file is not supported. It should be
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd

Any idea of what's going wrong ?

<persistence-unit name="audittrail">
 <jta-data-source>java:/DemoDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop" />
 </properties>
 <!-- ../ is a workaround for http://jira.jboss.com/jira/browse/EJBTHREE-724 -->
 <!--jar-file>../demo-1.0-SNAPSHOT.jar</jar-file-->
 <jar-file>file:/D:/demo/demo.ear/demo-1.0-SNAPSHOT.jar</jar-file>

 </persistence-unit>

Re-order the contents to move the jar-file element before the properties element as follows:

<persistence
 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"
 version="1.0">

<persistence-unit name="audittrail">
 <jta-data-source>java:/DemoDS</jta-data-source>

 <!-- ../ is a workaround for http://jira.jboss.com/jira/browse/EJBTHREE-724 -->
 <!--jar-file>../demo-1.0-SNAPSHOT.jar</jar-file-->
 <jar-file>file:/D:/demo/demo.ear/demo-1.0-SNAPSHOT.jar</jar-file>

<!--Jaikiran: Moved this after the jar-file element -->
<properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop" />
 </properties>
 </persistence-unit>
</persistence>

Having said that, i am not sure whether the xml validation should be strict on the ordering of the child elements of persistence-unit.

Just looked at the XSD http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd. The elements in the persistence-unit are enclosed within a <xsd:sequence> and so the order IS important. So yes, changing the order in your persistence.xml is the right way to fix this exception.

Thank you. I haven't take care to the order.
