The non-UI part of EMF works with RAP out of the box. With the aid of the following bundles, EMF models can be created and accessed.
Even though these bundles express an optional dependency on
org.eclipse.core.resources, this dependency isn't required at runtime.
UI and Edit Framework
Since 2.6 M6, EMF provides branches of it's UI/Edit framework for use with RAP. The necessary bundles are available from the EMF software repository and can be used together with the RAP runtime (> 1.3 M6).
The minimal target of an EMF and RAP runtime consists of two p2 repositories, one for RAP and one for the EMF RAP support.
Please be sure to uncheck the "Include required software" option when adding the features from the repositories.
Targeting RAP as runtime
Open up the Properties view on your .genmodel file and set "Rich Ajax Application" to true.
After that you can generate your edit and editor code.
Launch the application
You can now launch the application via it's generated IApplication. Just use the LibraryEditorAdvisorApplication entrypoint.
