Issue
BE GENEROUS AND TELL US WHY I AM HAVING THIS SILLY ISSUE
Everything works fine with no mapping! but I have a simple issue. I have set a parent mapping @ "/hello" and sub-mapped a method @ "/showForm", Dispatcher is set to "/" but I get 404 (see code fig. 3). I couldn't find an answer to an issue SIMILAR to mine.
See code below & TAGS for my setup
Controller fig.1
@Controller
@RequestMapping("/hello")
public class HelloWorldController {
@RequestMapping("/showForm")
public String showForm() {
return "hello-world";
}
web.xml fig.2
<servlet>
<servlet-name>yktech</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>yktech</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

... CARRIES ON SHOWS NO ERRORS....
Solution
Issue is in the view resolver bean, the prefix does not have a "/" in the beginning causing Spring to call any parented mapping requests from root rather than from /WEB-INF/view
