Hello.

I am trying to deploy a very basic OSGi Swing based app using the p2 app director. I am essentially following the process explained by Jeff McAffer in http://eclipsesource.com/blogs/2009/05/05/remote-provisionin g-with-p2/

When I run my launch configuration for the deploy, I get a NullPointerException which states "A null service reference is not allowed", stack trace below.

I am using the following args:

Program args:

-console -clean -application org.eclipse.equinox.p2.director.app.application
-metadataRepository file://scratch/prova/repository
-artifactRepository file://scratch/prova/repository
-installUI prova2
-version 1.0.0.qualifier
-destination /scratch/prova
-bundlepool /scratch/prova

VM args:

-Declipse.p2.data.area=/scratch/prova -Dosgi.noShutdown=true

I am using Eclipse 3.6.

Any ideas as to what I may be doing wrong?

TIA,
B.
