Subject [jira] Commented: (OPENJPA-1688) PersistenceMetaDataFactory does not recorgnize http://java.sun.com/xml/ns/persistence Namespace and throws Exception
Date Wed, 13 Oct 2010 20:05:32 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12920741#action_12920741
] 

Donald Woods commented on OPENJPA-1688:
---------------------------------------

What if you use the following, which works for our junits?
<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_2_0.xsd"
    version="2.0" >

Also, only using <persistence> will fail with JAXB 2.1, but works with JAXB 2.0.5....

> 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.

> 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.
