Duplicate Loading of META-INF/orm.xml if specified in perstistence.xml ---------------------------------------------------------------------- Key: EJB-339 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-339 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.1.GA Environment: JBoss 4.2.2.GA Sun Java 6 Reporter: Mirko Novakovic Priority: Minor I had specified <mapping-file>/META-INF/orm.xml</mapping-file> in my persistence.xml to load the standard orm.xml, which included some named queries. When deploying and starting the application in JBoss, I get the following exception: org.hibernate.DuplicateMappingException: Duplicate query mapping After removing the <mapping-file>/META-INF/orm.xml</mapping-file> from my perstistence.xml, the application works fine. It seems that the EntityManager loads the default META-INF/orm.xml and the one specified in the persistence.xml, even if they are the same. This is not a big issue, but took me some time to find it out and I think it would be better to log a warning in this case or just ignore duplications. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
