EventAdmin ServiceReference is always null? [message #66621]

Hello,

I am unable to obtain a valid ServiceReference for the EventAdmin service
shipped with 3.2RC3. The start method in my Activator class looks like
this:

public void start(BundleContext context) throws Exception {
ServiceReference serviceRef =
context.getServiceReference(EventAdmin.class.getName());
// serviceRef is always null!
}

The following items are selected in both the Eclipse
"Window->Preferences->Plug-in Development->Target Platform->Plug-ins" and
"Run->Run...->Plug-ins->Target Platform" areas:
- org.eclipse.equinox.log(1.0.0.v20060206)
- org.eclipse.osgi(3.2.0.v20060505)
- org.eclipse.osgi.services(3.1.100.20060426)

My manifest contains the following header and everything compiles nicely:
Import-Package: org.osgi.framework, org.osgi.service.event,
org.osgi.util.tracker

I'm running Eclipse 3.2-RC3 (Version 3.2.0, Build ID I20060505-1306) with
Sun's JRE 1.5.0_06 on Windows XP Professional SP2.

Note that I am able to get a ServiceReference to the LogService. Any help
is greatly appreciated.

Thanks,
Cameron Ross.

You need to include the org.eclipse.equinox.event bundle in your target.
You can get the optional service bundle implementations from the
equinox download site at.

http://download.eclipse.org/eclipse/equinox/

You can download each bundle individually or the equinox feature which
includes most of the equinox bundles (notice that
org.eclipse.equinox.ds) is currently not included in the feature.

When you use the org.eclipse.equinox.event bundle make sure it is
started so that it can register the EventAdmin service you need.
