  Five Things I Love About Spring
Subject:   Some errors in the code

The constructor for CommandLineView constructs a RentABike using new RentABike - there is no concrete implementation of RentABike.

More importantly, clv does not have a setRentABike method, so the Assembler is not able to do the injection.

Also, I do not understand why CommandLineView has a main method.

CommandLineView should look more like this:

public class CommandLineView {

private RentABike rentaBike;

public CommandLineView( ) {
//nothing to do here

public void setRentABike(RentABike rentABike){
this.rentABike = rentABike;

public void printAllBikes( ) {
System.out.println(rentaBike.toString( ));
Iterator iter = rentaBike.getBikes().iterator( );
while(iter.hasNext( )) {
Bike bike = (Bike)iter.next( );
System.out.println(bike.toString( ));

I hope this helps
