No mapping found for HTTP request with URI - Why won't my page load?

[Ray Clark]

Hi, I am new to Spring and I can't get the configuration right so that my page comes up. I bet that it is a simple configuration problem but I have exhausted myself with internet searches, reading through and trying examples, reading and rereading the 2 Spring books that I have and still no luck. I am hoping that someone can point out my configuration problem.

Thank you, here is my code:

My URL is:
http://localhost:8080/DVDTracker5-0/searchMainView.htm

When I use this URL the page doesn't come up and it doesn't seem to get to the controller.  This URL doesn't work either:

http://localhost:8080/DVDTracker5-0/searchMain.htm

    </bean>

</beans>

Controller:

package com.home.dvdtracker.controller;

import com.home.dvdtracker.service.SearchDvdServiceInt;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.support.SessionStatus;


@RequestMapping("/searchMainView.htm")
@Controller
public class SearchMainController {

    @Autowired
    private SearchDvdServiceInt searchDvdService;

    @RequestMapping(method = RequestMethod.GET)
    public String setupForm(ModelMap uiModelMap) {
        return "searchMainView";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String processSubmit(BindingResult result, SessionStatus status) {
        return "searchMainView";
    }
}

The JSP is /WEB-INF/jsp/searchMainView.jsp

The index and main page come up fine, but when I click on the link to go to this search page I get a 404 not found.  Specifically:
No mapping found for HTTP request with URI [/DVDTracker5-0/searchMain.htm] in DispatcherServlet with name 'dispatcher'|#]

I appreciate it if someone can suggest what is wrong with my configuration.

Thanks,
Ray

try changing

 <servlet-mapping>  
        <servlet-name>dispatcher</servlet-name>  
        <url-pattern>*.htm</url-pattern>  
 </servlet-mapping>  

to

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

Thank you for the reply. I read some of the tips for new posters like myself and I see that I posted way too much code. I apologize.

Ok, I changed the servlet mapping in the web.xml to be / instead of *.htm as suggested and the URL /DVDTracker5-0/searchMainView.htm still gets:

No mapping found for HTTP request with URI [/DVDTracker5-0/searchMainView.htm] in DispatcherServlet with name 'dispatcher'|#]

The controller has @RequestMapping("/searchMainView.htm") so I don't understand why the dipatcher servlet doesn't know which controller to send the request to.

No need to be sorry, I think you posted just the right amount of code. Most everything you posted was relevant to figuring out the issue.

You are missing

<mvc:annotation-driven/>

in your dispatcher-servlet.xml. This is different from <tx:annotation-driven /> and comes out of a different namespace. There is a thread floating around here somewhere from a few weeks back explaining what it does..
