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