Hello Eclipse users,

I'm new to EMF. For my next project I want to use EclipseLink as OR-mapper to store data permanently in a database (MySQL in my case). So, I've looked about an appropriate framework and found Teneo for modelling with EMF.

In my next step, I've tried to configure the Manifest file as described in this http://wiki.eclipse.org/Teneo/EclipseLink For adding the mysql jdbc driver, which I downloaded beforce, I've copied the jar file in the dropins folder of my Eclipse installation. After this, I've created a simple one-class-model (for testing purposes only) and tried to generate an orm.xml file. As result, I get a NullpointerException with the following error:

15.05.2010 11:07:00 org.eclipse.emf.teneo.classloader.ClassLoaderResolver setClassLoaderStrategy
INFO: Class loader strategy set to: org.eclipse.emf.teneo.classloader.ContextClassLoaderStrategy

I'm absolutely helpless.
What I have exactly to do to integrate the mysql jdbc driver and EclipseLink in EMF Teneo such as in the http://wiki.eclipse.org/Teneo/Hibernate/Download_and_Install ?

Thanks in advance

Hi Philipp,
Do you still see an orm.xml generated (eventhough you get an error)?

Is what you see similar to what is described in this bugzilla?
https://bugs.eclipse.org/bugs/show_bug.cgi?id=312587

I do not really have good experience with the dropins folder. You can also install some dependencies (mysql, hsqldb)
from this update site:
http://www.elver.org/eclipse/update

Did you add the dependencies to teneo/commons.logging to the model project as described in:
http://wiki.eclipse.org/Teneo/EclipseLink#Generating_the_orm .xml_through_the_menu

As a side remark, I am not sure if your project is for a web (service) application or for a RCP. If it is for a web
(service) application then this project maybe of interest for you:
http://wiki.eclipse.org/Texo

I am currently adding orm-generation to Texo. This will be released in a few days from now.

btw, Teneo is supported on the main EMF newsgroup which I added as a cc to this post.

Hi,

I have the same Problem.
I use Indigo.

Additionally I could not add the Import dependency
org.apache.derby.jdbc to the project, since the default Installation of Indigo does not offer it.

How can I workaround that?

Is the Teneo Project still alive?
I would love to use it really, but I never saw it running anywhere else than on eclipseCon 2009 Smile

Hi Marcel,
The Teneo-EclipseLink integration is *not* alive, the Teneo-Hibernate is very much alive and delivered/maintained in
multiple versions.

For using EMF with EclipseLink you can consider the EMFT Texo project:
http://wiki.eclipse.org/Texo
