Declarative Service in a class created by eclipse extension point [message #534625]

Hi

in my eclipse rcp application, I would like to use an osgi service via declarative service in a wizard. therefore, I implemented the wizard as my component class referencing the desired service. as the wizard is added via the standard eclipse extension point, this construction somehow does not work.

what is the best design pattern for such a case?

Thanks in advance,
Luzi

Hi,

afaik there's a possibilty to instruct the ExtensionRegistry to not
create the instances itself but let the contributor do this using a
factory method. You could use this mechanism to return the component
created by EquinoxDS in your wizard contribution.

Martin Lippert wrote a nice article with same sample code in how to let
Spring create RCP Views:

Maybe this helps,
Regards,
Stefan.
