Hello,
I am new to this forum and trying to learn Spring.
I have a problem with a ModelAndView in my controller
and was wondering if anyone can help me out.

I hava a simple Administrator login page, when the administrator
logged in succesfully he comes to a page with a link directing to
a list of products. When he clicks te link I pass the list in a ModelAndView
with the JSP path it needs to call, but it seems to look for a different path.

Here is the admin page:

And here is the controller code

@Controller
@RequestMapping("/administrator")
@SessionAttributes("adminSession")
public class AdministratorController{
    private final AdministratorService administratorService;
    private final ProductService productService;

@Autowired
    public AdministratorController(AdministratorService administratorService, ProductService productService) {
        this.administratorService = administratorService;
        this.productService=productService;
    } 
    
    @RequestMapping(method=RequestMethod.GET)
    public String createLogin(HttpSession session){
        if(session.getAttribute("adminSession") !=null){
            return "administrator/adminpage";}
        else{return "administrator/adminlogin";}
    }
    
    @RequestMapping(method=RequestMethod.POST)
    public String login(@RequestParam("gebruikersnaam") String gebruikersnaam,
            @RequestParam("paswoord") String paswoord, HttpSession session){
        Administrator adminPoging=administratorService.findGebruikersnaam(gebruikersnaam);
        if(administratorService.adminLogin(adminPoging, paswoord)==true){
            session.setAttribute("adminSession", adminPoging);
            return "administrator/adminpage";
        }
        else{return "administrator/adminlogin";}
    }
    
    @RequestMapping(value="producten", method=RequestMethod.GET)
    public ModelAndView productList(){
        return new ModelAndView("administrator/productlijst", "producten", productService.findAll());
    }
}

I also use a prefix and suffix in my controller xml file as you can see here:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context" 
       xmlns:mvc="http://www.springframework.org/schema/mvc" 
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.1.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
    
        <context:component-scan base-package="com.chocowereld.web"/>
        <mvc:annotation-driven/>
        <mvc:resources mapping="/images/**" location="/images/*"/>
        <mvc:resources mapping="/styles/**" location="/styles/*"/>
        
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/JSP/" />
            <property name="suffix" value=".jsp" />
        </bean>
</beans>

So when I click the link on the administrator page I expect it to look for
"/ChocoWereld/WEB-INF/JSP/administrator/productlijst.jsp", instead i get:
"The requested resource (/ChocoWereld/WEB-INF/JSP/administrator/producten.jsp) is not available.".

I must be making some mistake but I can't figure it out. Help would be much appreciated.
Thanks!

What you have should work. Try cleaning out the contents of your wptwebapps directory cleaning your workspace and republishing the code. Maybe something is not getting updated correctly on your application server. Also try setting a break point and starting in debug mode. Do you have another handler method that could be getting the request and returning a view name of producten?

First of all I thank you for your reply. I don't find a wptwebapps directory anywhere on my system. I tried to
re install my tomcat server but I keep having the same problem. The only handler methods I have so far
are the ones in my controller I posted above. When I try to google my particular problem it also seems
I am the only person having this, it's really weird.

Now suddenly without any change to the code the administrator login page stopped working too,
when i try to login it looks for the url: "http://localhost:8080/ChocoWereld/administrator/administrator".

You have the dispatcher servlet mapped to / in the web.xml?

Hi, I resolved the issue.
It was a wrong import in my controller.

Should be:
