Hi!
i've read through quite a lot of articles regarding teneo.
afaik its supposed to generate the orm.xml file _and_ annotations on the source code (right?)
i've created a very simple project with an ecore, persistence.xml file etc.
i generate my model (works fine)
i generate the orm.xml (works fine, but i get a INFORMATION log:
i guess i can simply ignore this one?
Quote:org.eclipse.emf.teneo.classloader.ClassLoaderResolver setClassLoaderStrategy
Information: Class loader strategy set to: org.eclipse.emf.teneo.classloader.ContextClassLoaderStrategy
then i tried to use the generated code, but every time i launch a test
i get the following:
Quote:The collection of metamodel types is empty. Model classes may not have been found during entity search for Java SE and some Java EE container managed persistence units. Please verify that your entity classes are referenced in persistence.xml using either <class> elements or a global <exclude-unlisted-classes>false</exclude-unlisted-classes> element
that's why i looked at the code and i do not find any annotations on the code (interfaces nor impl)
thats why i do not wonder nothing can be found...
can someone help me?
i am using the following versions:
EMF 2.7.1
Ecore Tools 1.0.0
EMF Teneo EclipseLink 1.2.0
this is my EPerson.ecore:
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="eperson"
nsURI="http://eperson/1.0" nsPrefix="eperson">
<eClassifiers xsi:type="ecore:EClass" name="EPerson">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
<eStructuralFeatures xsi:type="ecore:EAttribute" name="age" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EInt"/>
</eClassifiers>
</ecore:EPackage>

Hi Ludwig,
The prefered way of using teneo is using Hibernate, for hibernate you can let Teneo do the mapping internally.
If you want jpa/orm.xml then I suggest looking at the EMFT Texo project which provides generation of jpa annotated code
from ecore/xsd models:
http://wiki.eclipse.org/Texo

Probably there is not so much difference between hibernate and eclipselink. Have you looked at CDO?
If that does not work for you then for a RCP I would use Teneo with Hibernate.
