Hello,

I am in the midst of porting a project from Glassfish to Wildfly 8.1.
This is a maven-project.

This is my environment:

$ mvn -ver
mvn Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.7.0_75, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-45-generic", arch: "amd64", family: "unix"

I am using eclipselink as the JPA-implmentation.
Tested the connection, saved and retrieved an entity from the database - so that is working.
This is a snippet from my pom.xml

<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.5.2</version>
</dependency>
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
<version>2.5.2</version>
<scope>provided</scope>
</dependency>

And my JBOSS_SERVER holds : wildfly-8.1.0.Final/modules/system/layers/base/org/eclipse/persistence/main
1. eclipselink-2.5.2.jar
2. jipijapa-eclipselink-1.0.1.Final.jar
3. module.xml

Here is my super-class:

@Entity
@Table(name = "MEDIA")
@NamedQueries(

Unknown macro: { @NamedQuery(name = "Media.FindByUuid", query = "SELECT c FROM Media c where c.uuid = }

)
@Inheritance(strategy = InheritanceType.JOINED)
public abstract class Media implements Serializable {

and here is my child-class:

@Entity
@Table(name = "IMAGE")
@NamedQueries(

Unknown macro: { @NamedQuery(name = Image.FIND_ALL, query = "SELECT i FROM Image i") }

)
@XmlRootElement
public class Image extends Media implements Serializable {

The following is not working and giving me 'null' in Wildfly, but working in Glassfish.

Query query = em.createNamedQuery("Media.FindByUuid");
// hardcoding the UUID, which I have in my database :
query.setParameter("uuid", "000d8f7c-6c7b-4c56-9799-ac67666462b5");
T media = (T) query.getSingleResult();

Not understanding the advises given in this thread.
Could you help me to narrow my troubleshooting ?
am I doing something wrong or ...
Should I upgrade eclipselink ? Should I go for Wildfly 8.2 ?
Should I change Inheritance-strategy ?
