Using either reflection or direct instantation I've got a new exception:

The code I use is the following:

 public ResultSet getResultSet() throws SQLException {
	
	    org.postgresql.Driver driver = new org.postgresql.Driver();
	
	Connection connection = DriverManager.getConnection( this.databaseName, 
this.username, this.password );
	Statement statement   = connection.createStatement();
	return statement.executeQuery(" SELECT * FROM "+  this.tableName );
    }


Any idea?

Thanks,
Luca
