Incurred 2 exceptions after copying your examples directly.
(1) In Spring3HelloWorldTest, the ClassPathResource path must be absolute, rooted to the project's src dir. So, the correct construction for that line is:
XmlBeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("net/roseindia/SpringHelloWorld.xml"));
(2) Probably a windows thing, but the xml file text cntl-c'd directly from this page carried some invisible characters over on paste which caused an exception in SaxParser. Just needed to delete and replace the whitespace there.
