PersistenceMetaDataFactory does not recorgnize
http://java.sun.com/xml/ns/persistence Namespace and throws Exception
--------------------------------------------------------------------------------------------------------------------
Key: OPENJPA-1688
URL: https://issues.apache.org/jira/browse/OPENJPA-1688
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Roman Zulauf
I have a Java project with a persistence.xml and an orm.xml in the META-INF
folder. Both persistence.xml and orm.xml files contain JPA Persistence
Meta-Data. OpenJPA can correctly parse my persistence.xml but it needs network
access to parse the orm.xml because of the schema location specified as
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";. When parsing
persistence.xml OpenJPA does not access the network to retrieve the specified
schema.
The exception thrown is:
Caused by: <openjpa-2.0.0-r422266:935683 nonfatal general error>
org.apache.openjpa.persistence.PersistenceException: org.xml.sax.SAXException:
jar:file:/C:/WMPS/wmcc.jar!/META-INF/orm.xml [Location: Line: 6, C: 19]:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of

If I remove the schema location from the orm.xml file, another exception is
thrown:

Because the used Parser factory is not under the control of the application,
there seems to be no way to set the schema location programmatically. If there
is way, it seems to be missing in the documentation.
