Basic Spring MVC config: PageNotFound using InternalResourceViewResolver

Question

I'm trying to get a first Spring 3 MVC setup running.

My app is running on tomcat, with in the server context of "grapevine"

For the purposes of testing, I'm trying to get requests from http://localhost:8080/grapevine/test to render the contents of WEB-INF/jsp/noSuchInvitation.jsp

When I try this, I'm getting a 404, and the logs suggest that my jsp isn't present:

WARN  org.springframework.web.servlet.PageNotFound  - No mapping found for HTTP request with URI [/grapevine/WEB-INF/jsp/noSuchInvitation.jsp] in DispatcherServlet with name 'grapevine'

I must have mis-configured this somewhere, but I can't see what I've done wrong.

Here's all the relevant snippets.

Web.xml:

<servlet>
    <servlet-name>grapevine</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>grapevine</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

From my context:

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

Controller:

@Controller public class ParticipantInvitationController {

@RequestMapping("/test")
public ModelAndView test()
{
    return new ModelAndView("noSuchInvitation");
}

Log:

DEBUG org.springframework.web.servlet.DispatcherServlet  - Rendering view [org.springframework.web.servlet.view.JstlView: name 'noSuchInvitation'; URL [/WEB-INF/jsp/noSuchInvitation.jsp]] in DispatcherServlet with name 'grapevine'

Answer 1

This is because the <url-pattern> in your web.xml is too "wide". A value of /* means that the servlet is configured to receive all requests, and that includes the request from the servlet to the JSP. The error message you're seeing is from DispatcherServlet, which is receiving its own forwarded request.

You should pick a more specific <url-pattern>, e.g. <url-pattern>/xyz/*</url-pattern>, so that your URL then becomes http://localhost:8080/grapevine/xyz/test, and then it should work fine.
