How to save/load Preferences to DB? [message #1272968]

Hello,
is it possible to override the save/load-Method of the preferenceStore? I would like to use a DB as backend.

How can I do this? Need I a special IScopeContext or a own PreferencesStore? Can I extend existing classes?

Thanks a lot.

Marco

Hi Marko,
you have to create and register your own SettingStoreFactory. See [1]
and [2] for more details.

Hello,

In RAP, eclipse preferences are delegated to org.eclipse.rap.rwt.service.SettingStore

so you can achieve that by writing your own SettingStore implementation, that will persist preferences in DB instead of file.
You have also to implement SettingStoreFactory that will provide your SettingStore implementation.
I guess you have a Workbench application so you have to declare your factory using org.eclipse.rap.ui.settingstores extension and launch your application with -Dorg.eclipse.rap.rwt.settingStoreFactory=yourFactoryName

In RWT standalone it is a bit simpler, the SettingStoreFactory can directly be set on the Application
