				This example retrieves values contained in an Oracle OBJECT type. The example uses the table and types created in e296 Creating an OBJECT Type in an Oracle Database. 
				    try {
				        // Create a statement
				        Statement stmt = connection.createStatement();
				    
				        // Select rows from object1_table
				        ResultSet resultSet = stmt.executeQuery("SELECT * FROM object1_table");
				    
				        // Get the OBJECT values from each row
				        while (resultSet.next()) {
				            // Get the integer from the first column col_integer of the row
				            int i = resultSet.getInt(1);
				    
				            // Get the object1 value from the second column col_object1
				            oracle.sql.STRUCT object1 = (oracle.sql.STRUCT)resultSet.getObject(2);
				    
				            // Get the object1 values from each row
				            Object[] object1Values = object1.getAttributes();
				    
				            // Get the first value of object1, which is a string
				            String str = (String)object1Values[0];
				    
				            // Get the second value of object1, which is of the type object2
				            oracle.sql.STRUCT object2 = (oracle.sql.STRUCT)object1Values[1];
				    
				            // Get the values of object2
				            Object object2Values[] = object2.getAttributes();
				            str = (String)object2Values[0];
				            BigDecimal num =  (BigDecimal)object2Values[1];
