The following steps have to be performed before a process can use the UCB:
- Create and set the UNO service manager.
- Create an instance of the UNO service com.sun.star.ucb.UniversalContentBroker, passing the keys identifying a predefined UCB configuration to
createInstanceWithArguments().
There are several predefined UCB configurations. Each configuration contains data that describes a set of UCPs. All UCPs contained in a configuration are registered at the UCB that is created using this configuration. A UCB configuration is identified by two keys that are strings. The standard configuration is "Local" and "Office", which generally allows access to all UCPs available in a local installation.

String[] keys = new String[2]; keys[ 0 ] = "Local"; keys[ 1 ] = "Office"; xUCB = xServiceFactory.createInstanceWithArguments( "com.sun.star.ucb.UniversalContentBroker", keys ); } catch (com.sun.star.uno.Exception e) { } if (xUCB == null) return false; return true; }
