Hey,

I rather stumbled over EMF and I'm really intressted in the Framework. At the moment we're developing standard WTP projects without OSGi that use Hibernate for ORM with a multilayer concept( DAO-> Service -> Model -> View). It's working good. But probably we could achive a better documenting with EMF, besides the long term improvements from the code generating aspect.

Right now, I'm not completely sure if EMF is practicable for a web application and more important how the architecture should be in that case. At the moment I suppose that a combination of EMF, CDO and Teneo would be a good choice.

I think the question is rather clear, how could this scenario look, is there a best practice?

Thank you,

Christoph Grotz

Hi Christophe,
It depends a bit what type of web apps you write. If it is with GWT then Ed Merks has been working on making a GWT
enabled version of EMF. I am sure he sees this thread and give some more info.

On the server side you can use Teneo for automatic EMF-ORM mapping (to hibernate).

To use EMF/Teneo or Texo you just need to add a number of jars to the WEB-INF/lib, that's all. See here:
http://wiki.eclipse.org/Teneo/Hibernate/Download_and_Install #Install_Teneo_for_use_within_a_Web_Container

Another project which might be interesting is the Texo project which is mainly focused on the server side of web-apps
for now:
http://wiki.eclipse.org/Texo

It gives you the benefits of EMF functionality but with more possibilities to integrate it into other frameworks which
can't handle the EMF specific list implementations.
http://wiki.eclipse.org/Texo/Texo_and_EMF

Texo also provides orm generation, xml/xmi serialization, template overriding, etc.
