Connecting To Db4o

The only thing left - is a connection to the db4o_osgi plug-in. It can be established upon the plug-in start and terminated upon the plug-in stop:

Activator.java: start
/**
   * (non-Javadoc)
   * @see org.eclipse.ui.plugin.AbstractUIPlugin#start(BundleContext)
   * Obtains a db4o_osgi service reference and registers it with Db4oProvider
   */
  public void start(BundleContext context) throws Exception  {
    super.start(context);
    ServiceReference serviceRef = context.
getServiceReference(Db4oService.class.getName());
    Db4oService db4oService = (Db4oService)context.getService(serviceRef);
    Db4oProvider.Initialize(db4oService);
  }
Activator.java: stop
/**
   * (non-Javadoc)
   * @see org.eclipse.ui.plugin.AbstractUIPlugin#stop(BundleContext)
   * Unregisters the db4o_osgi service from Db4oProvider
   */
  public void stop(BundleContext context) throws Exception  {
    Db4oProvider.UnInitialize();
    plugin = null;
    super.stop(context);
  }
