Answer 1

+2 A:

Your web.xml is mapping the Spring DispatcherServlet to the url pattern /ct/* on top of the location your web application is being deployed to.

So if your web application is being deployed to /ct try going to http://localhost:8080/ct/ct/helloWorld

Chances are that you want the Spring DispatcherServlet to be mapped to all urls for your web application. Change the servlet-mapping to:

<servlet-mapping>
    <servlet-name>ct</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

and your original url should work as expected.

OK, now requests reaches the controller, thanks.But when controller whants to render the view, request to JSP-view is being served by DispathcerServlet, I've got following message in console:WARNING: No mapping found for HTTP request with URI [/ct/WebContent/WEB-INF/helloWorld.jsp] in DispatcherServlet with name 'ct'and result is again 404 page. Is there any way to serve jsp request bypassing DispatcherServlet?

OK, try changing the class of your view resolver to org.springframework.web.servlet.view.InternalResourceViewResolver.UrlBasedViewResolver expects to be able to translate your symbolic view name into a URI it can use to render the view. That's probably not what you want to do.Generally you don't want your JSP views directly accessible, and by putting them under WEB-INF they're not. InternalResourceViewResolver will be able to access them though.

Changing view resolver to InternalResourceViewResolver did't help. In http://stackoverflow.com/questions/1234298/can-springmvc-be-configured-to-process-all-requests-but-exclude-static-content-d/1235311#1235311 there is advise to use SimpleUrlHandlerMapping to exclude addresses containing '.jsp' from served by Spring DispatcherServlet. I wonder, how can I do this?

Answer 2

A:

Have you created your helloWorld.jsp page?

I tried out your code (NB: using 2.5.6), and saw a 404 on the browser, and the following error message in the server log:

File "/path/to/my/WEB-INF/helloWorld.jsp" not found

Where /path/to/my will be different for your env.

Without helloWorld.jsp, the view resolver will fail. Adding this jsp, and all is well.

Answer 3

A:

The path in your RequestMapping should be the full path, not just the pathInfo (the stuff after the matched string in the web.xml). So your RequestMapping should specify @RequestMapping("/ct/HelloWorld")

Alternatively, your problem may be that you aren't running your app as the root app and is actually running at the path /ct. In that case, your web.xml isn't matching anything because the /ct which designates the application context is not used when comparing the url-patterns in order to determine the servlet context. In that case, you need to access the url /ct/ct/HelloWorld in order to send the request to your servlet. But you'll still need @RequestMapping("/ct/HelloWorld") in order for the controller to be mapped to that request (but it doesn't care about the initial /ct which designates the app).

Personally, I actually think it is clear to map based on a suffix, but to use a generic suffix. I map *.html to my servlet and controllers which respond to those requests send back html. Similarly, I use *.json and *.xml for json and xml requests. I handle static html and other static content at the load balancer, so tomcat never sees them.

Answer 4

+1 A:

OK, for now solution is:

web.xml

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

HelloWorldController.java

@Controller
public class HelloWorldController {

    @RequestMapping("/helloWorld")
    public String list() {
     return "helloWorld";
    } 
  }

ct-servlet.xml

<bean
     class="org.springframework.web.servlet.view.InternalResourceViewResolver">
     <property name="prefix" value="/WEB-INF/jsp/" />
     <property name="suffix" value=".jsp" />
    </bean>

    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
