The main problem was with <url-pattern>*.html</url-pattern>.
I did following changes in your code and i am able to run the same code on my machine :
1) changed <url-pattern>*.html</url-pattern> to <url-pattern>/</url-pattern>
2) copied jstl-1.2.jar in lib folder.

Just change your controller as follows
@Controller
@RequestMapping("/hello")
public class HelloWorldController {
@RequestMapping(method = RequestMethod.GET)
public String helloWorld(ModelMap model, HttpServletRequest request) {
String message = "Hello World, Spring 3.0!";
System.out.println(message);
model.addAttribute("message", message);
return "hello";
}
}
hope this will solve your problem
