AW: [eclipselink-users] eclipselink doesn't find my persistence.xml

[Steffen Förster <foerster@xxxxxxxx>]

Thanks for the answers so far. The entities are spread over many jars in /plugins. 

How is your application configured?
- Java SE? Java EE(which server)?	Java SE
- Where is your persistence unit jar/directory? /bin/database.jar
- Where is your persistence.xml? /bin/META-INF
- What does your persistence.xml look like? 
- Are all those things on your classpath? Yes
- How are you getting the EntityManagerFactory/EntityManager? Persitence.createEntityManagerFactory(name,properties)


persistence.xml:
<?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"; version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";>
  <persistence-unit name="sapr" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <class>...</class>
	...
    <class>...</class>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="eclipselink.target-database" value="Auto" />
    </properties>
  </persistence-unit>
</persistence>

Do you see this problem when running a simple JPA program, or just when trying 
to generate a cannonical model?

How is your application configured?
- JavaSE? Jave EE(which server)?
- Where is your persistence unit jar/directory?
- Where is your persistence.xml?
- What does your persistence.xml look like?
- Are all those things on your classpath?
- How are you getting the EntityManagerFactory/EntityManager?
