Hi Martin,

Recently I noticed that dao class is not generated for abstract class.
I don't know why. To me, such dao classes should be generated because it is allowed to pass a abstract class to EntityManager.find to get all the instances of one class hierarchy.

What do you think?

Hi Oliver,
Yes makes sense what you say. I changed it and am doing a new build. Will post here after I published it.

Hi Martin,

Thanks for fix, I tested the build, but it seems the problem still exists.
I debugged into the code and I found maybe the following logic in ModelEClassAnnotator.setAnnotationFeatures causes the problem:

if (!GenUtils.isDocumentRoot(eClass) && !eClass.isInterface() && !eClass.isAbstract() && !ModelUtils.isEMap(eClass)
&& GeneratorUtils.isEmptyOrNull(annotation.getDaoQualifiedClassName())) {
final EPackageModelGenAnnotation ePackageModelGenAnnotation = getEPackageModelGenAnnotation(eClass.getEPackage());
final String packagePath = ePackageModelGenAnnotation.getDaoClassesPackagePath();
annotation.setDaoQualifiedClassName(packagePath + GenConstants.DOT + annotation.getSimpleClassName()
+ getDaoPatternName(ePackageModelGenAnnotation));
} else {
// prevent dao generation
annotation.setDaoQualifiedClassName(null);
}

Could you verify it again?

Hi Oliver,
Yes you are right, I am developing some other features so I don't have a working (local) build at the moment, but will
rebuild asap, will be a few days probably..

No problem!
I can wait.

By the way, which exciting feature are you developing? Razz

Hi Oliver,
The past weeks I added a JSON webservice layer:
http://wiki.eclipse.org/Texo/JSON_REST_Web_Services
http://martintaal.wordpress.com/2012/04/05/emf-texo-json-rest-web-service-support-connecting-your-client-to-an-emf-supporting-web-server/

I am now working on support for EMF Resources. This makes it possible to develop RCP's on top of Texo generated jpa
entities. I have developed an EMF resource which uses JPA to persist/query the database. This supports 2-tier architect
where the RCP talks directly to the database. My next step is to develop an EMF resource which talks json with a backend
web server. This combines the work I for the JSON webservice layer. So then you can have a 3-tier architecture: RCP -
[json] - webserver - database

Then after that I will develop a RIA/html5 user interface which will work with the JSON web service layer.

A smaller thing I added is that it is possible to generate the code in another project (see the texo project
properties). This will be available after I get a new build done...

Hi Oliver,
I published a new build which should solve the dao issue you reported here.
