Thanks Thomas!
Your hint was just what I needed. OJB and hsqldb work
quite nicely together and they are the perfect pair
for client side application that need to persist data.
Now the db goes directly into the user HOME directory
:-) I just pasted the piece of code to perform the
trick just below.
Thanks again
Denis
MetadataManager meta = MetadataManager.getInstance();
String userDir = System.getProperty("user.home");
userDir = userDir + "\\.planning\\db";
JdbcConnectionDescriptor descriptor =
meta.connectionRepository().getDescriptor(new
PBKey("default","sa",""));
descriptor.setDbAlias(userDir);
PersistenceBroker broker =
PersistenceBrokerFactory.createPersistenceBroker(new
PBKey("default","sa",""));
