Assuming you have the file to load, you can install the bundle like:

void install( BundleContext context, File file) throws Exception {
    Bundle b = context.installBundle( file.toURI().toString() );
    b.start();
}

And you can uninstall it (if the file is gone):

void uninstall( BundleContext context, File file) throws Exception {
    Bundle b = context.getBundle( file.toURI().toString() );
    b.uninstall();
}

You get the BundleContext from your activate or Declarative services component's activate method. These are the recommended methods but in dire cases you can also use:

BundleContext context = FrameworkUtil.getBundle( this.getClass() ).getBundleContext();

Though handy it bypasses some mechanism that you might want to use in the future so getting the context in the recommended way is much better
