49 	a service manager.
50 	The service manager can create a few basic services, whose implementations  are:
51 	<ul>
52 	<li>com.sun.star.comp.loader.JavaLoader</li>
53 	<li>com.sun.star.comp.urlresolver.UrlResolver</li>
54 	<li>com.sun.star.comp.bridgefactory.BridgeFactory</li>

56 	<li>com.sun.star.comp.connections.Acceptor</li>
57 	<li>com.sun.star.comp.servicemanager.ServiceManager</li>
58 	</ul>
59 
60 	Other services can be inserted into the service manager by
61 	using its XSet interface:
62 	<pre>
63 		XSet xSet = UnoRuntime.queryInterface( XSet.class, aMultiComponentFactory );
64 		// insert the service manager
65 		xSet.insert( aSingleComponentFactory );
