Report persistence.xml missing when trying to enhance openJPA entity from
eclipse
---------------------------------------------------------------------------------
Key: OPENJPA-2021
URL: https://issues.apache.org/jira/browse/OPENJPA-2021
Project: OpenJPA
Issue Type: Bug
Components: Enhance
Affects Versions: 2.1.0
Environment: Win 7, Eclipse 3.6, MySQL 5.5
Reporter: hangchen222
I try to enhance the entity in my project with OpenJPA, and get the result as
followed.
But in fact it DOES existed for when I deploy the project the OpenJPA can visit
the persistence.xml and read the JDBC connection.
Please be free to contact if any more info required and thanks in advance.

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.
