Ecore ODA Driver
The Ecore ODA Driver has been implemented in two projects:
- An interim driver was created as a DTP Incubator project. Its latest status can be found in Bugzilla 132958.
- A second official and more functional ODA driver has been added to EMF ECore for Indigo M4. See bug 330988 for details. This official EMF implementation effectively obsoletes the interim DTP Incubator implementation.
Tim has written a tutorial for the Ecore ODA Driver at Overcoming Fear.
Below you'll find some of the information common to both drivers (Unless noted) but without the detail or pretty pictures.
Interim Driver - Backport to Eclipse 3.2, EMF 2.2 and JDK 1.4
For the original driver a backport of these plug-ins was checked-in to CVS for use with Eclipse 3.2, EMF 2.2 and JDK 1.4. The backport has no guarantee of future support. If you would like instructions for using these versions of the plug-ins, please look here.
Connection Properties and Profiles
In order to support requests for Connection Profiles and Connection Properties, we made some changes as of August 22, 2008 that will affect existing reports, i.e., the Model file location is now stored directly as a URI, the property for this URI has been renamed, Column Selections are contained in a single property (instead of in properties with increasing numbers), and the name of the Column Selection property has been changed. Hopefully these fixes will not be too disruptive to existing reports and the benefit of dynamic property binding will outweigh the inconvenience of either manually editing existing reports or re-creating those reports.
The Ecore ODA Driver build package is available on the DTP download page. The source is available from CVS. After obtaining the code, you may notice the driver has a number of dependencies that might be un-met in your workspace:
Using the Driver
Those less familiar with EMF or without a handy EMF model should install the EMF Examples from http://www.eclipse.org/modeling/emf/updates and create an instance of an .extlibrary file with some data. It's outside the scope of this document to describe this process, but typical readers will already have familiarity with EMF editors.
Of course, any serialized EMF model will do, as long as the package has been registered so that the Java classes representing the model are available at runtime.
Create a Report
Create an Ecore ODA Data Source
Any ODA drivers registered with the platform show up within BIRT as data source types, each with a wizard to allow for the entry of connection information. In the case of the Ecore ODA Driver, the only information required by the connection is the path to a serialized Ecore model of a registered model type. (If you aren't familiar with registering EMF models, see this question in the EMF/FAQ.) Attempting to load a serialized model for an unregistered package will result in an error.
Create an Ecore ODA Data Set
Once a data source has been created for your Ecore model, use the New Data Set wizard to launch the Ecore ODA Data Set Wizard.

The Ecore ODA Driver and UI can be checked out of CVS from the Datatools_Project Repository of dev.eclipse.org with a path of org.eclipse.datatools.incubator/plugins.
