NOTE: the documentation for Hibernate is currently (January 2010) being transferred from the current site to the Eclipse wiki. This means that:

  • the pages in the wiki can be incomplete until the transfer is complete. For the complete documentation visit the current site: here.
  • the pages refer to a new build setup and dependency definition which is not yet available in Teneo. The new Teneo versions will be build when the site has been transferred completely.

The EMF - Hibernate integration supports all EMF features and standard Hibernate features. EMF objects can be persisted in most major relational databases and retrieved using an EMF resource approach or HQL queries.

A distinctive feature of Teneo is that you can override/extend the Model-Relational mapping using JPA annotations in the model, see the JPA/EJB3 pages for more information.

Teneo offers full support for EMF XML Schema constructs, see the Teneo XML Schema pages for more information.


The EMF, Hibernate and Teneo versions are related as follows:

  • Teneo 1.0.4: for Eclipse 3.4-3.3/EMF 2.4-2.3/hibernate 3.2/3.3.1 and jdk 1.5
  • Teneo 1.1.0: for Eclipse 3.5/EMF 2.5/hibernate 3.2/3.3.1 and jdk 1.5
  • Teneo 1.1.1/1.1.2: Maintenance Builds for Eclipse 3.5/EMF 2.5/hibernate 3.3.2 and jdk 1.5
  • Teneo 1.2.0: Stable Builds for Eclipse 3.6/EMF 2.6/hibernate 3.3.2 and jdk 1.5


Note: the difference in hibernate versions between the 1.1.0 and 1.1.1 and higher builds. Hibernate introduced a binary incompatibility in version 3.3.2, forcing Teneo to adhere to this.

Overview, Download & Install and Quickstart

  • Architecture Overview: describes the components of the Teneo solution and how they interact and work with Hibernate.
  • Download and Install: describes downloading and installing Teneo for usage in OSGI as well as Web Container environments. Also the installation/download of the example projects used in the tutorials is discussed here.
  • Quickstart: starting from an ecore model, the tutorial shows how to work with the generated model code and persist the objects in a (generated) database.

Tutorials

The tutorials are based on the example project which can be downloaded from cvs into Eclipse.

Configuration and Usage Details

  • Configuration Options: Teneo has many (40+) configuration options controlling mapping and runtime behavior.
  • Teneo extensions: the Teneo extensions mechanism allows you to override and replace core Teneo components with your own implementations.
  • EMF Hibernate Integration Details: discusses several detailed aspects of the integration between Hibernate and EMF, for example: use of a package registry, classloading, escaping of table and column names, synthetic id and version, etc.
  • Hibernate Resource: discusses the Teneo specific implementation of the EMF Resource concept.

Model Relational Mapping with EJB3/JPA Annotations

Teneo can map practically every ecore model to a relational store. The mapping logic can be overridden and controlled by in-model JPA annotations. The annotations are entered in the model (xsd or ecore) directly or set in a separate XML file.

This combination of automatic mapping and manual overrides with JPA annotations is very powerfull. The JPA annotations allow a developer to do many things, for example: determine the naming of columns and tables, enables or prevents join tables, specify embedded components, specify the name of foreign key columns, the inheritance mapping, if an index column is used, the sorting of a collection, enable external references, etc. etc.

For more information, see the following pages:

  • Supported annotations: gives a complete overview of the support for JPA annotations including Hibernate annotation extensions and convenience Teneo extensions.
  • Annotations format: describes in detail how annotations can be specified in the model itself or in a separate XML file. By supporting an external XML it is possible to annotate existing ecore models, so without the need to change them.
  • Association Mapping: describes in detail how associations can be mapped to a relational store, also outlining which annotations and configuration options can be used.

XML Schema Support

Teneo supports practically all XML Schema constructs which are also supported by EMF. Teneo tries to generate a sensible, practical, readable and performant database schema for a XML Schema model. It is important that the domain model concepts are also reflected in the database schema itself.

For more details on the Teneo XML Schema support, visit the following pages:

CVS, Support and FAQ

The Teneo source code can be found here (CVS):

  • dev.eclipse.org
  • /cvsroot/modeling
  • org.eclipse.emf/org.eclipse.emf.teneo

If you encounter issues, check the FAQ page.

Support for Teneo is given on the EMF newsgroup. For accessing the news group through a browser visit this page.

Teneo Continuous Build

Teneo is build using Buckminster and Hudson in a continuous build system. The Teneo nightly build job can be found here.

For a detailed description on Teneo's build setup see this page.

The update site containing the latest successful nightly builds: https://build.eclipse.org/hudson/job/emf-teneo-nightly/lastSuccessfulBuild/artifact/build/result/p2site/
