Hi Jacek,
I think this is some threading issue. First of all remember that in the
start/stop methods of BundleActivator you shouldn't spawn a long running
task (just use a new Thread to do this). In the javadoc to
org.osgi.framework.BundleActivator#start() method is written:
Called when this bundle is started so the Framework can perform the
bundle-specific activities necessary to start this bundle. This method can
be used to register services or to allocate any resources that this bundle
needs.
This method must complete and return to its caller in a timely manner.
Otherwise you can block the OSGi console thread.
I suspect that installing and resolving the Spring bundle may consume some
amount of time and it should be in the "start" method. Moreover nesting a
start of another bundle in your bundle is not the best idea. I am
wondering if you are using OSGi console and you are able to install and
start your bundle why you don't install and start the spring bundle?
Anyway I think that BundleListener resolves your issue:
package pl.jaceklaskowski.osgi;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.BundleEvent;
import org.osgi.framework.BundleException;
import org.osgi.framework.BundleListener;
public class AktywatorPakunku implements BundleActivator, BundleListener {
Logger log = Logger.getLogger(AktywatorPakunku.class.getName());
private Bundle bundle;
public void start(BundleContext bundleContext) throws Exception {
// add bundle listener
bundleContext.addBundleListener(this);
bundle = bundleContext.installBundle(
"file:c:/projs/osgi/spring-osgi-activationpolicy/target/spring-osgi-activationpolicy-1.0.jar"
);
long bundleId = bundle.getBundleId();
String bundleLocation = bundle.getLocation();
String bundleSymbolicName = bundle.getSymbolicName();
System.out.println("------------------------------------");
System.out.println("Charakterystyka zainstalowanego pakunku:");
System.out.println(" Identyfikator: " + bundleId);
System.out.println(" Identyfikator położenia: " +
bundleLocation);
System.out.println(" Nazwa symboliczna: " + bundleSymbolicName);
System.out.println("------------------------------------");
}
public void stop(BundleContext bundleContext) throws Exception {
// remove bundle listener
bundleContext.removeBundleListener(this);
log.info("stop() wykonano - czyszczę po sobie");
}
public void bundleChanged(BundleEvent event) {
if (event.getType() == Bundle.RESOLVED &&
event.getBundle() == bundle) {
try {
System.out.println("Startuję pakunek " +
bundle.getSymbolicName());
bundle.start();
} catch (BundleException e) {
log.log(Level.SEVERE, e.getMessage());
}
}
}
}

where spring-osgi-activationpolicy-1.0.jar is a bundle with
Bundle-ActivationPolicy: lazy I meant to test out.
