Any language binding supported by UNO establishes interprocess connections using a local service manager to create the services necessary to connect to the office. Refer to chapter UNO Interprocess Connections for additional information. The following client program connects to a running office and retrieves the com.sun.star.lang.XMultiServiceFactory in C++:
#include <stdio.h> #include <cppuhelper/bootstrap.hxx> #include <com/sun/star/bridge/XUnoUrlResolver.hpp> #include <com/sun/star/lang/XMultiServiceFactory.hpp> using namespace com::sun::star::uno; using namespace com::sun::star::lang; using namespace com::sun::star::bridge; using namespace rtl; using namespace cppu; int main( ) { // create the initial component context Reference< XComponentContext > rComponentContext = defaultBootstrap_InitialComponentContext(); // retrieve the service manager from the context Reference< XMultiComponentFactory > rServiceManager = rComponentContext->getServiceManager(); // instantiate a sample service with the service manager. Reference< XInterface > rInstance = rServiceManager->createInstanceWithContext( OUString::createFromAscii("com.sun.star.bridge.UnoUrlResolver" ), rComponentContext ); // Query for the XUnoUrlResolver interface Reference< XUnoUrlResolver > rResolver( rInstance, UNO_QUERY ); if( ! rResolver.is() ) { printf( "Error: Couldn't instantiate com.sun.star.bridge.UnoUrlResolver service\n" ); return 1; } try { // resolve the uno-URL rInstance = rResolver->resolve( OUString::createFromAscii( "uno:socket,host=localhost,port=2002;urp;StarOffice.ServiceManager" ) ); if( ! rInstance.is() ) { printf( "StarOffice.ServiceManager is not exported from remote process\n" ); return 1; } // query for the simpler XMultiServiceFactory interface, sufficient for scripting Reference< XMultiServiceFactory > rOfficeServiceManager (rInstance, UNO_QUERY); if( ! rOfficeServiceManager.is() ) { printf( "XMultiServiceFactory interface is not exported\n" ); return 1; } printf( "Connected sucessfully to the office\n" ); } catch( Exception &e ) { OString o = OUStringToOString( e.Message, RTL_TEXTENCODING_ASCII_US ); printf( "Error: %s\n", o.pData->buffer ); return 1; } return 0; }
