Hi,
To study OSGI declarative serivce, I write an example consisting of Service provider and client to use the service. I has already download the org.eclipse.equinox.ds and start it. But no right result can be gotten. And can not find related service is registed by console command!
I attached the related jars and please help to find problems caused by my false understanding of DS specificetion.
appreciate your help!
dsexample provide a service named "NameService" which check a String wehter it is among the name sets predefined;
dsexampleclient is a client application to use above service to check the String from input end.

OK, Maybe we can choose a simpler example to recognize my errors. That is just about a service out of following 4 files, installed it in Equinox and then started it and expected to see "com.sample.service.SampleService" among installed services, but it is not there. I am definitely doing something wrong but cannot figure out what.
I copy some important files here:
==========================================
package "com.sample.service" include two file, one is service interface named as "SampleService", another is the related implement named as "SampleServiceImpl"! Following is source code:
(1)
public interface SampleService {
public void service();
}
(2)
import org.osgi.service.component.ComponentContext;
import org.eclipse.equinox.ds.*;
public class SampleServiceImpl implements SampleService {
public SampleServiceImpl(){
super();
System.out.println("SampleServiceImpl is constructed!");
}
public void service() {
System.out.println("Sample service is called");
}
protected void activate(ComponentContext context) {
System.out.println("SampleService Component Active,within the bundle lifecircle.");
}
protected void deactivate(ComponentContext context) throws Exception {
System.out.println("SampleService Component Deactive,within the bundle lifecircle.");
}
}
===================================================
package mysampleservice has one file implementing BundleActivator to activate the related bundle:
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import com.sample.service.*;
public class Activator implements BundleActivator {
/*
* (non-Javadoc)
* @see org.osgi.framework.BundleActivator#start(org.osgi.framework. BundleContext)
*/
public void start(BundleContext context) throws Exception {
//SampleServiceImpl ss = new SampleServiceImpl();
System.out.println("BundleActivator is started!");
}
/*
* (non-Javadoc)
* @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.B undleContext)
*/
public void stop(BundleContext context) throws Exception {
System.out.println("BundleActivator is stopped!");
}
}
=======================================================
Related META-INF has two files:
(1)activator.xml
<?xml version="1.0" encoding="UTF-8"?>
<component name="sample.service" immediate="true">
<implementation class="com.sample.service.SampleServiceImpl"/>
<service>
<provide interface= "com.sample.service.SampleService"/>
</service>
<component>
(2)Manifest for bundle
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: MySampleService Plug-in
Bundle-SymbolicName: MySampleService
Bundle-Version: 1.0.0
Bundle-Activator: mysampleservice.Activator
Bundle-Localization: plugin
Service-Component: /META-INF/activator.xml
Bundle-Description: Immediate component activator
Import-Package: org.osgi.framework, org.eclipse.equinox.ds, org.osgi.service.component
Require-Bundle: org.eclipse.osgi, org.eclipse.osgi.services, org.eclipse.core.runtime
Bundle-Vendor: CRL
Export-Package: com.sample.service
Eclipse-AutoStart: false
