> The nested classpath element inside the mappingtool ant task are ignored when loading
the persistent configuration file. User got the following error:
> <openjpa-2.0.2-SNAPSHOT-r422266:1361284M fatal user error> org.apache.openjpa.util.MetaDataException:
MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null).
This might mean that no configuration properties were found. Ensure that you have a META-INF/persistence.xml
file, that it is available in your classpath, or that the properties file you are using for
configuration is available. If you are using Ant, please see the <properties> or <propertiesFile>
attributes of the task's nested <config> element. This can also occur if your OpenJPA
distribution jars are corrupt, or if your security policy is overly strict.
