hi,
I have just started with the library tutorial on elver.org. The library xsd
is attached.
I have done the following things:
1) created model and edit plugins for the library xsd
2) setup a hsql server instance , created a library db and modified the
hibernate properties accordingly.
3) I am using the versions we got from the eclipsecon2008 Teneo session in
model-driven-dev tutorial on first day.
[ except hsql related, which I took the latest from hsql.org ] .

here is the test method I am invoking from a view class of another plugin ..

public String testAddBook(){
final String dataStoreName = "LibraryDataStore";
final Session session = StoreController.getInstance().getSession();
final Transaction tx = session.getTransaction();
session.beginTransaction();
//Create and populate Library
Library library = LibraryFactory.eINSTANCE.createLibrary();
library.setName("My Library");
// Make it persistent.
session.save(library);
// Create a writer...
Writer writer = LibraryFactory.eINSTANCE.createWriter();
writer.setName("JRR Tolkien");
// ...and one of his books.
Book book = LibraryFactory.eINSTANCE.createBook();
book.setAuthor(writer);
book.setPages(305);
book.setTitle("The Hobbit");
book.setCategory(BookCategory.SCIENCE_FICTION);
// Add the Writer and Book to the Library. They are made
// persistent automatically because the Library is itself
// already persistent.
library.getWriters().add(writer);
library.getBooks().add(book);
//Commit Transaction and close Session
//The Library is not stored in the database until you commit the
Transaction:
session.getTransaction().commit();
session.close();
}

During database schema update call, I am getting the following error .

Could not determine type for:
org.eclipse.emf.teneo.hibernate.mapping.ENumUserType, at table: book, for
columns: [org.hibernate.mapping.Column(category)]
org.hibernate.MappingException: Could not determine type for:

What am I missing ?

Appreciate your help

Hi Prasad,
How does the StoreController initialize the Teneo datastore, can you post that part of the code?

Hi Prasad,
This could also be a class-loading/plugin dependency issue (that hibernate can not see the teneo
hibernate.mapper classes).

Can you let me know how you setup the hibernate libraries? Did you put them in a separate plugin
with Eclipse-Buddypolicy: dependent in the manifest.mf?

Ok good, btw you can simplify the initialization of the datastore by getting rid of the part that
reads the epackage on the basis of the nsuri, if you have programmatic access (at compile time) to
the epackages then you can also do this:

localDataStore.setEPackages(new EPackage[]{LibraryPackage.eINSTANCE});

Hi Prasad,
How does the StoreController initialize the Teneo datastore, can you post that part of the code?

Hi Prasad,
This could also be a class-loading/plugin dependency issue (that hibernate can not see the teneo
hibernate.mapper classes).

Can you let me know how you setup the hibernate libraries? Did you put them in a separate plugin
with Eclipse-Buddypolicy: dependent in the manifest.mf?

Great !! That did the trick. Sorry about missing that instruction in the
first place.

Ok good, btw you can simplify the initialization of the datastore by getting rid of the part that
reads the epackage on the basis of the nsuri, if you have programmatic access (at compile time) to
the epackages then you can also do this:

localDataStore.setEPackages(new EPackage[]{LibraryPackage.eINSTANCE});
