derby.system.home is a static property that must be set before Derby 
starts, i.e. before the driver is loaded (I assume you are using the 
embedded driver). When you call getConnection(...), Derby has already 
started, so the new property value will have no effect. Does setting the 
property before loading the driver (Class.forName(...)) resolve your issue?
