MT>> Hmm, not really.. I have had another request to support standard JPA/orm.xml instead of the EclipseLink specific
version. So I have thought about doing that.
But what do you mean with the 'jee glassfish server creates an orm.xml', you mean that the glassfish server expects that
the orm.xml should have this namespace?

Hi Martin,
regarding the Texo2EMF conversion.
I have found out that ModelEMFConverter works differently in OSGi and non OSGi environments. In an OSGi environment like an Eclipse plugin everything works as expected.
My problem is that I try to convert the Texo model object into my EMF object in an non OSGi environment (JEE/EJB3). I did exactly the same:
- I have a ecore describing a user and its address
- I generated the Texo model code (texo.User, texo.Address)
- I generated the ecore model code from the genmodel to transfer my emf.User instances to my RCP because of JPA dependency that are waved into JPA objects, so Texo POJO's too.
- Now I tried the ModelEMFConverter on the server, which work very well, but the return typ is a EObject (DynamicEObjectImpl) instead of an emf.UserImpl in OSGi
- Now I have to create a emf.User from the DynamicInstance.
Is this a bug?
I have installed the glassfish JEE server plugins for the web tools platform. This plugins generate an orm.xml with the:
version="2.0" xmlns="[url]http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm
http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
reference.
The glassfish server uses eclipselink as jpa provider. I have tested the texo-generated orm.xml. It worked very well in an EJB3.1. I dont know, if other JEE servers like Geronimo with other persistence providers (OpenJPA, Hibernate) work with the eclipselink scheme reference in the orm.xml.
Currently I work on a RCP that is connected to a JEE server. For this I could imagine following feature to get a "tool-chain" using texo:
- create sql statements for tables, triggers from my model
- create jee-resources (usually xml files)
- create annotated EJB, EAR, WAR components from my ecore (stateless, stateful, message driven, timer, webservice, servlets, web.xml, application.xml)
- JPA already works 
- JAXB
- finally I would use Texo to create a osgi service facade that delegates service calls to the jee server in my RCP
All that could be generated from an ecore model. I already created an implementation of the last point using jet.
I am already a beginner with the EMF stuff and used ecore as application model in my RCP's.
I would provide some help, if needed, because Texo fits my future needs very well.

Mark

MT>> The ModelEMFConverter does this:
eObject = (InternalEObject) EcoreUtil.create(eClass);
So if the eClass belongs to your generated EPackage then it should create an emf.User.
Note that you can tell Texo which EPackageRegistry to use:
ModelResolver.getInstance().setEPackageRegistry(Registry);
So if your generated EPackage is present in the registry used by Texo then it should create the emf.User.
Maybe you can debug into the ModelEMFConverter.createTarget method to see what happens.

Hi Martin,
I have installed the glassfish JEE server plugins for the web tools platform. This plugins generate an orm.xml with the:
version="2.0" xmlns="[url]http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence/ormhttp://java.sun.co m/xml/ns/persistence/orm_2_0.xsd"
reference.
The glassfish server uses eclipselink as jpa provider. I have tested the texo-generated orm.xml. It worked very well in an EJB3.1. I dont know, if other JEE servers like Geronimo with other persistence providers (OpenJPA, Hibernate) work with the eclipselink scheme reference in the orm.xml.
Because of the Texo to EMF conversion, I try to explain my question again:
- I have a ecore describing a user and its address
- I generated the Texo model code (texo.User, texo.Address)
- I generated orm annotation using Texo
I use the Texo model object and orm.xml on the jee server
- I generated the ecore model code from the genmodel to use my User instances in my RCP (for databinding) (emf.User, emf.Address)
Now I tried the ModelEMFConverter, which work very well, but the return typ is a EObject (DynamicEObjectImpl).
So if I convert texo.User into EMF I get the DynamicEObjectImpl, but I want the emf.User.
Now I need turn the DynamicEObject into emf.User instances. Can you tell me how I can achieve this?
Currently I work on a RCP that is connected to a JEE server. For this I could imagine following feature to get a "tool-chain" using texo:
- create sql statements for tables, triggers from my model
- create jee-resources (usually xml files)
- create annotated EJB, EAR, WAR components from my ecore (stateless, stateful, message driven, timer, webservice, servlets, web.xml, application.xml)
- JPA already works :)
- JAXB
- finally I would use Texo to create a osgi service facade that delegates service calls to the jee server in my RCP
All that could be generated from an ecore model. I already created an implementation of the last point using jet.
I am already a beginner with the EMF stuff and used ecore as application model in my RCP's.
I would provide some help, if needed, because Texo fits my future needs very well.

Mark

Hi Mark,

MT>> The ModelEMFConverter does this:
eObject = (InternalEObject) EcoreUtil.create(eClass);
So if the eClass belongs to your generated EPackage then it should create an emf.User.
Note that you can tell Texo which EPackageRegistry to use:
ModelResolver.getInstance().setEPackageRegistry(Registry);
So if your generated EPackage is present in the registry used by Texo then it should create the emf.User.
Maybe you can debug into the ModelEMFConverter.createTarget method to see what happens.

I tried to generate jaxb annotations inside Texo also but I encountered too many issues in that Texo generated classes

MT>> yes please do so, I am very interested to extend Texo and feedback and other help is greatly appreciated. I am also
looking for people who want to work with me on this, so if you think that specific generation logic (for the wsdl for
example) could be provided as part of Texo then just let me know.
