static final String DRIVER ="org.basex.api.xqj.BXQDataSource"; Why use the class org.basex.api.xqj.BXQDataSource??? In JDBC driver is associated with a database. Why in XQJ I use a class???

In JDBC you're as well referencing the driver implementation. This is how you instantiate e.g. MySQL with JDBC:

Class.forName("com.mysql.jdbc.Driver").newInstance();
