I should also mention this wiki page, in case you haven't found it yet. http://wiki.eclipse.org/Equinox/p2/Adding_Self-Update_to_an_RCP_Application
It gives a good overview of how we *thought* you might want to reuse the p2
UI in RCP apps.

Hi Susan,
thanks for the hint, that solved the NPE problem. However I'm still a bit
lost in reusing the P2 UI in my RCP view (I do not want to reuse the whole
P2 wizard dialog (see screenshot), just the content of the pages). When I
start my application I get an empty page that looks totally different than
the install wizard dialog. Taking a closer look at the API of
InstalledSoftwarePage I found the following comment:
* @noinstantiate This class is not intended to be instantiated by clients.
That seems to be the wrong way of trying to include the P2 software
installation process into my RCP view. Is it even possible to put the P2
wizard pages into RCP Views oder Editors?

Hi, Eugen.
Those NPE's indicate that the basic provisioning services have not been
initialized properly. The event bus and the profile registry are not being
found.
A common cause for this is the absence of the declarative services bundle
in the launch config (or in the build). Without ds, the basic provisioning
service declarations won't be found.
We have tried to include more reasonable error messages for the common
trigger points of this problem, but depending on how you are reusing p2,
your symptoms may be different (such as here).
Here is an old thread discussing this problem.

Let me know if this is not what's causing your issue.

Hi folks,
I'm trying to reuse some P2 UI elements as introduced in this presentation:
http://www.slideshare.net/PascalRapicault/discovering-the-p2-api
Basically I would like to reuse the"Available Software"-page where I can
choose/edit update sites and features to install, the "Install
Details"-page which summarizes the items to be installed and the licenses
page. I would like to integrate all this pages in my RCP-View, not in a
Wizard.
Trying to reuse the "InstalledSoftware"-page resulted in a NPE (note: I've
checked the box "Support software installation in the launch application"
in my launch configuration):
InstalledSoftwarePage installedSoftwarePage = new InstalledSoftwarePage();
installedSoftwarePage.createControl(parent);
