I felt the same issue. I added the jstl 1.2.jar and it worked for me.

Well i too faced this problem while following this tutorial and code above seems to be from this tutorial also,so Adding spring-webmvc-x-y-z.RELEASE.jar, and removing "asm" and "web.servlet" jars worked for me. Hope this would help someone learning spring.

Change the following in the web.xml

<servlet>

      <servlet-name>HelloWeb</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/HelloWeb-servlet.xml</param-value>
        </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <servlet-mapping>
      <servlet-name>HelloWeb</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

I had a similar problem and I believe it was Maven-related. What I did is I changed jstl dependency from jstl:jstl:1.2 to javax.servlet:jstl:1.2 . I do not believe that this was the reason but after Maven updated its dependencies - it started working. Then it made no difference which one I used. I think it had to do with libs being not in the right place...

Once check your folder structure.. all spring jars should be copied in lib folder that is in Web-INF and import from there. That should solve your issue

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
