When using the sample Java client to store/retrieve binary/raw files I have to execute separate open/close commands.  It is my understanding that this locks the database.  In a multi-user scenario, such locking is undesirable as binary/raw files can be quite large.  And since there is no alteration of the indexes etc during such operations, is there a better way? Also, why isn't there a corresponding retrieve method on the Java client, similar to the store method?

BaseXClient session = new BaseXClient(host, port, username, password);
session.execute("open " + database);
session.store(path, inputStream);
session.execute("close");
