If you are just learning Spring, I recommend not using the BeanFactory, but an ApplicationContext object instead.

Also, is your hello.xml in the root of your classpath?

Then the only code you would need to start up Spring is

ApplicationContext context = new ClassPathXmlApplicationContext("hello.xml");

then just use
Hello hello = context.getBean("hello");

I also recommend putting your classes into packages, instead of the root package, like you are doing.

Right! We're on it! Let's get to work tiny ad!
