[CDO] Persistance Strategy for Java Objects [message #1456380]

I have been working with a RCP application. I have been using Java Serialization for persisting java objects in files. In my application, i am generating in memory ecore but i have my own data model (java classes) and i serialize that to be saved in file.

What can be best Strategy for me to make my objects persistable using CDO? I have a big code base and i need to trasform them in EMF.... I have multiple ideas for it but i need to adopt the best recommended appraoch for this.

So should i create an ecore visually (representing my own data model) and then generate code from that and then try to copy functionality related code to newly generated code from my own old data model?

Should i annotate my own data model using annotation so EMF can understand it?

Do i really need to EMFy my own data model? Can i use CDO without EMF?

Cheers,

Hi ModelGeek,

If you want to use CDO you must use EMF. Ideally you even regenerate your model with some CDO-specific generator
properties (see the basic tutorials) that rely on standard EMF implementation classes being used.

If you have questions about how to turn a legacy application in to an EMF-modeled one I suggest you repost them in a
separate thread without "CDO" in the title. Then it's more likely that you attract the EMF experts here ;-)

Cheers
