'''INSTALLED''' - The bundle has been installed into the OSGi container, but some of the bundle's dependencies have not yet been met. The bundle requires packages that have not been exported by any currently installed bundle.

For instance a typical Java class implementing the <code>[http://www.osgi.org/javadoc/r4v42/org/osgi/framework/BundleActivator.html BundleActivator]</code> interface is shown below in the [https://guest:1673852@zenit.senecac.on.ca/svn/ecl500/Lectures/trunk/w11-osgi-simple-serviceprovider/src/cs/ecl/osgi/simple/bookfinderservice/Activator.java Sample Bundle from your course]:
<source lang="java">
package cs.ecl.osgi.simple.bookfinderservice;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import cs.ecl.osgi.simple.bookfinder.BookFinder;
import cs.ecl.osgi.simple.bookfinderservice.internals.BookFinderImplementation;
public class Activator implements BundleActivator {
private static BundleContext context;
static BundleContext getContext() {
return context;
}
public void start(BundleContext bundleContext) throws Exception {
Activator.context = bundleContext;
BookFinder bookService = new BookFinderImplementation();
context.registerService(BookFinder.class.getName(), bookService, null);
System.out.println(" Bookfinder service registered ");
}
public void stop(BundleContext bundleContext) throws Exception {
Activator.context = null;
System.out.println(" Bookfinder service stopped ");
}
}
