/** Bootstrap offers functionality to obtain a context or simply
a service manager.
The service manager can create a few basic services, whose implementations are:
<ul>
<li>com.sun.star.comp.loader.JavaLoader</li>
<li>com.sun.star.comp.urlresolver.UrlResolver</li>
<li>com.sun.star.comp.bridgefactory.BridgeFactory</li>
<li>com.sun.star.comp.connections.Connector</li>
<li>com.sun.star.comp.connections.Acceptor</li>
<li>com.sun.star.comp.servicemanager.ServiceManager</li>
</ul>
Other services can be inserted into the service manager by
using its XSet interface:
<pre>
XSet xSet = (XSet)UnoRuntime.queryInterface( XSet.class, aMultiComponentFactory );
// insert the service manager
xSet.insert( aSingleComponentFactory );
</pre>
