Thanks Stephane.
I noticed the reference to WorkbenchAdapterBuilder.registerAdapters() last
night and updated my code appropriately. I found that I can now see my
projects plus their names in the Resource Navigator tree and that .project
files have an icon. Unfortunately, the projects don't have an icon and
when I delete projects they seem to disappear _but_ upon re-running my
application the projects are back (actually, the references are back, the
projects themselves were deleted).
I'm going to look into workspace saving because that's probably what's not
happening at the moment and I think Ill probably be able to sort out the
missing icon issue too.
I find it difficult to gripe about Eclipse, it being so wonderful, and I
know that documentation is always something that most of us prefer to put
off. Nonetheless, it is unfortunate that (i) documentation for so many
'straightforward' scenarios plug-in is often non-existent and (ii) when
someone is kind enough to respond to resolve such problems the solutions
turn out to involve internal code. Developers could conclude that the
Eclipse people don't want third-party plug-ins to be written. Obviously
this is not the case. I have always thought that the documentation is out
by an order of magnitude in detail.*
There is certainly plenty of scope for someone to write a good plug-in
book (unlike the latest plug-in book which is just a rehash of the online
documentation).

* For example, I found that adapting the standard New Java Project
wizard by adding many new steps was particularly nightmare-ish. Even
simple things take much time to resolve: like changing the standard
behaviour of allowing the user to press Esc to dismiss the wizard: I allow
it in the early steps but prompt for confirmation after a significant
amount of data has been entered.

Chris Laffra pointed me to http://eclipsefaq.org where I found:
Chapter 17. Workspace and Resources API
How and when do I save the workspace?
which prompted me to search the Eclipse source where I discovered that:
org.eclipse.ui.internal.ide.IDEWorkbenchAdvisor
stores the workspace during:
WorkbenchAdvisor.postShutdown()
Also, be sure to do:
configurer.setSaveAndRestore(true);
in:
WorkbenchAdvisor.initialize()

It seems, if we struggle all together we can get that navigator
working ... ;-D
In the meantime I've managed to resolve the missing-icons-issue: All
the default icons need to be registered. This code mas copied from
the IDEWorkbenchAdvisor:
public void initialize( IWorkbenchConfigurer configurer ) {
...
String PATH_ETOOL = ICONS_PATH + "etool16/"; // enabled toolbar icons
Bundle ideBundle = Platform.getBundle( IDEWorkbenchPlugin.IDE_WORKBENCH );
declareWorkbenchImage( ideBundle, ISharedImages.IMG_TOOL_NEW_WIZARD, PATH_ETOOL + "new_wiz.gif", true );
...
}
private void declareWorkbenchImage( Bundle ideBundle, String symbolicName, String path, boolean shared ) {
URL url = ideBundle.getEntry( path );
ImageDescriptor desc = ImageDescriptor.createFromURL( url );
getWorkbenchConfigurer().declareImage( symbolicName, desc, shared );
}
Hope this helps ...
Best regards,
Andreas Rummler

Hi Andreas,
Thank you, I now have icons.
The next step is to strip out all the context menu stuff that I don't
need. I'm using feature-based self-hosting and have imported _all_ the
Eclipse features and plug-ins so I'm assuming that when I cut back to just
those that are needed by my RCP the undesired actions will go too.
