Hello,
I'm using eclipse to develope a project in witch I use some classes of
eclipse expecially some plugin.
I have an error with the class org.eclipse.core.runtime.Platform.
When I execute the instruction:
IExtensionRegistry registry = Platform.getExtensionRegistry();
registry is null. I think that I must to initialize the registry but I
don't know very well how do it and what is this registry.

Can you help me, please?

Best regards.

That seems odd. What type of application are you running your code in? =

Is it a full Eclipse Runtime application or are you trying something =

different like an OSGI or RCP app? You aren't by any chance setting =

eclipse.createRegistry=3Dfalse anywhere on the command line?

Mark.

Thanks for the answer.
I don't know very well what the registry must to contain and how it must
to be set! I run in an ambient OSGI but I don't have understand if I must
to load anything on the registry.
I've seen that perhaps I must to use the BundleContex, it's true? How can
I create and set this object?

Sorry - you are beyond me. I have never done an OSGI-only application. I
didn't think you had to do anything special, but you may need to start or
initialize something if you are doing low-level OSGI. You can probably
glean some info from the source for
org.eclipse.core.internal.registry.osgi.Activator, but you may be better
off asking your questions inf the eclipse.technology.equinox newsgroup.

Mark.

I have seen that the instruction Platform.getExtensionRegistry() always
return null. But it's impossible because in the installation of eclipse
the registry contain a lot of plug-in.

How is it possible?
