Can anyone help - getting a parse error on persistence xml that is stopping me at the first hurdle
I am running jboss eclipse v2 beta 2, and compiler is set to java 6.
unpacked all the hibernate, annotations and entity manager zips and included all the jars from the /lib and the main jar files into my class path
using mysql as the test database. I'm trying to do this as simple as possible in a j2se test mode at present before we stretch out for ejb3 containers etc.
i've created a simple app to test the entity manager/annotations and got stuck.
Hibernate version:
hibernate 3.2.1 GA all.
my project structure is
Code:
app
src
(def package)
app.java (main)
node.java (persistant annotated class)
persistentManager.java (returns entityManager from bootstrap load)
META-INF
persistance.xml
log4j.properties
my persistence.xml is as follows
Code:
<?xml version="1.0" encoding="UTF-8" ?>
<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="manager" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
- <properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
<property name="show_sql" value="true"/>
<property name="connection.driver_class" value="com.mysql.jdbc.Driver"/>
<property name="connection.url" value="jdbc:mysql//localhost/app"/>
<property name="connection.username" value="will"/>
<property name="connection.password" value=""/>
</properties>
</persistence-unit>
</persistence>
my persistnant manager class is follows
Code:
import javax.persistence.*;
public class PersistenceManager
{
// declare static factory
private static final EntityManagerFactory emf;
//initiatlise the factory at class loader time
static
{
System.out.println ("static method getting entity manager factory\n");
try {
// Create the EntityManagerFactory from META-INF/persistence.xml
emf = Persistence.createEntityManagerFactory("manager");
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial EntityManagerFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public EntityManager getEntityManager()
{
EntityManager em =emf.createEntityManager();
return em;
}
}
I have logging (default ) turned on.
my main app does the following
Code:
import javax.persistence.*;
public class App
{
/**
* @param args
*/
public static void main(String[] args)
{
// TODO Auto-generated method stub
PersistenceManager pm = new PersistenceManager ();
EntityManager em = pm.getEntityManager();
Node node = new Node ("my node");
em.persist(node);
System.out.println ("saved node called" + node.getNodeName());
}
}
what i get is an error from the parser at run time that I cant figure out

i've looked at the PDF file and my persistenace.xml looks okay (i think). I looked at the .xsd in the entity manager dir and it says persistence and persistence unit elements do have children - so why do i get the the
