Hibernate Metamodel Generator is not aware of persistence.xml for JPA 2.1 ------------------------------------------------------------------------- Key: WFLY-1412 URL: https://issues.jboss.org/browse/WFLY-1412 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Affects Versions: 8.0.0.Alpha2 Reporter: Juergen Zimmermann Assignee: Scott Marlow I'm using a snapshot of WildFly Alpha2. The latest usable version of the Hibernate Metamodel Generator is 1.2.0.Final which is only aware of JPA 2.1. If I use a persistence.xml with the new namespace for JPA 2.1, then I get the following (serious?) warning during compilation. I'm not sure whether this is a WildFly or a Hibernate warning. [WARNING] Hibernate JPA 2 Static-Metamodel Generator 1.2.0.Final [WARNING] Error unmarshalling /META-INF/persistence.xml with exception : javax.xml.bind.UnmarshalException - with linked exception: [org.xml.sax.SAXParseException; lineNumber: 12; columnNumber: 28; cvc-elt.1: Deklaration des Elements "persistence" kann nicht gefunden werden.] This is the beginning of persistence.xml: <?xml version="1.0"?> <!-- <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"> --> <persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd" version="2.1"> <!-- line 12 --> <persistence-unit name="de.shop.PU">
