Are you installing the plugins in Eclipse 3.4.2? In a recent post [1],
Brian Fitzpatrick wrote that you should use Eclipse 3.5M5 for DTP 1.7.
Older versions won't work.

Actually, you are looking for a DTP Incubator 1.6.x build. I don't know,
where to get one. However, since the Ecore driver comprises only the plugins
org.eclipse.datatools.enablement.oda.ecore
org.eclipse.datatools.enablement.oda.ecore.ui
it's easy to build them yourself. You can check out the sources via CVS
from :pserver:anonymous@dev.eclipse.org:/cvsroot/datatools from the
module org.eclipse.datatools.incubator/plugins.
The code in HEAD has already been updated to the enhanced interfaces of
DTP 1.7 and won't compile with DTP 1.6. Therefore, be sure to switch to
version v200901210800.
Shameless plug: Alternatively, you could give my driver [1] a try.

The Ecore file contains the model of your model (metamodel). Therefore,
you will see types such as EAttribute, EClass, EClassifier, or EReference.

I assume, you have already generated the model and editor code from your
Ecore file and its corresponding Genmodel. You can use that editor to
create an instance of your model. The data source for such a file will
provide you with "familiar" business objects.

The context type is the type of the variable "self" in the OCL query.
Usually, you start with a query on the root objects of your data file.
For example (also see the example report in [1]), the root object in an
Ecore file is usually an EPackage. To query all classes in this package
you can use a data set with the following properties:
input: contents of the resource specified in the data source
(default, if no value for parameter *input is provided)
context type: EPackage
query text: self.eClasses
result type: EClass
You can then continue with a data set for a class's attributes:
input: reference to an object
(for example row["*self"] from the data source above)
context type: EClass
query text: self.eAttributes
result type: EAttribute
Hope this helps.
