Connecting to a Data Source
The first step to access the configuration database is to connect to a configuration data source.
To obtain a provider instance ask the global com.sun.star.lang.ServiceManager for a com.sun.star.configuration.ConfigurationProvider. Typically the first lines of code to get access to configuration data look similar to the following:
// get my global service manager XMultiServiceFactory xServiceManager = (XMultiServiceFactory)UnoRuntime.queryInterface( XMultiServiceFactory.class, this.getRemoteServiceManager( "uno:socket,host=localhost,port=2083;urp;StarOffice.ServiceManager")); final String sProviderService = "com.sun.star.configuration.ConfigurationProvider"; // create the provider and remember it as a XMultiServiceFactory XMultiServiceFactory xProvider = (XMultiServiceFactory) UnoRuntime.queryInterface(XMultiServiceFactory.class, xServiceManager.createInstance(sProviderService));
This code creates a default com.sun.star.configuration.ConfigurationProvider. The most important interface a com.sun.star.configuration.ConfigurationProvider implements is com.sun.star.lang.XMultiServiceFactory that is used to create further configuration objects.
The com.sun.star.configuration.ConfigurationProvider always operates in the user mode, accessing data on behalf of the current user and directing updates to the user's personal layer.
The backend data store has several shared layers. One of these layers is used to store shared default data. The files for this layer are located in the share directory of the Apache OpenOffice installation. Additionally, there are special layers that are used by the Extension Manager for deploying configuration data associated with extensions. For details, see Extensions.
Arguments can be provided that determine the default behavior of views created through this com.sun.star.configuration.ConfigurationProvider. The following parameter may be used for this purpose:
||The user's locale.||This parameter was called "|
|The default configuration provider obtained when no arguments are given will always be the same object. Be careful not to call dispose() on this shared com.sun.star.configuration.ConfigurationProvider.|
