In a simple program i have a problem to use the EventAdmin service. As
described i put the org.eclipse.equinox.event bundle in my worbench.
In a simple application i tried to get the service in the Activator with
the following statements:
ServiceTracker eaTracker = new ServiceTracker(context,
EventAdmin.class.getName(), null);
eaTracker.open();
EventAdmin ea = (EventAdmin) eaTracker.getService();
and all i get is:
!ENTRY org.eclipse.osgi 4 0 2007-08-27 11:28:16.917
!MESSAGE An error occurred while automatically activating bundle
ch.post.pf.sample.simpleeas (19).

I resolved the problem. The import of the bundle as "Projects with
source folder" doesn't work. The result is an invalid Activator...????
I added the jars in Runtime/Classpath and no errors are shown. But it
doesn't work. Strange behaviour!!!
Found it by starting the bundles by hand over the console.
I imported the projects as binary projects and all worked.
