Page hyperlink navigation with Spring MVC @Controller

[james loveay]

Hi all,

I've been working on this for a while but can't seem to find the right way to go with it.

I want to be able to log in to a system, then on clicking on a hyperlink go to another page which will display a list of objects.

I'm using Spring MVC 3.1 with @Controller classes and the navigation goes from one .jsp to another .jsp page.

I've tried a few things and have considered SWF but think that is a little over what I need to do for this, also there seems to be no examples that I have been able to find, unless I'm getting a search term wrong.

So this is the code that I have

<!-- main menu page --> 
   <a href="/loanbooks">Loan Books</a>

MainMenuController File

@Controller
@RequestMapping("/mainmenu")
public class MainMenuController {
    
    @EJB(mappedName = "java:global/SpringBookLibrarySystem/BookFacade")
    private BookFacadeLocal bookFacade; 
    
    public void setBookFacade(BookFacadeLocal bookFacade){//DI used here (setter) 
        this.bookFacade = bookFacade; 
    }
    
   //what goes here? 
   public String getLoanBooks(Model model){
       List bookList = bookFacade.notOnLoan(); 
       model.addAttribute("bookList", bookList); 
       return "loanbooks";  
   }

I have tried the @RequestMapping("/loanbooks") also @RequestMapping(value = "/loanbooks", method = RequestMethod.GET)

Both have failed, either returning a 404 or returning a mapping issue, if I can get the mapping correct between the jsp and the controller and there is still a problem then I think that I require a mapping in the xml file but I'm just not sure where I'm going wrong.

Can somebody take the time to have a look at this and explain what I'm missing.

Many thanks in advance.

I think though that I'll try to use SWF and see how I go with that, hopefully I can make another post soon to let you know how I got on with it.

Hi all,

just an update, Have solved the problem.

Again another simple one that I just couldn't figure out and stumbled on it just by luck but I know what I did so that's great for later.

Just wanted to input the code changes so that anybody with the same problem can follow and not go around the houses like I have been.

<!-- main menu jsp --> 

 <a href="/SpringBookLibrarySystem/loanbooks.htm">Loan Books</a>

The controller class was changed

@Controller
public class LoanBooksController {
    
    @EJB(mappedName = "java:global/SpringBookLibrarySystem/BookFacade")
    private BookFacadeLocal bookFacade; 
    
    public void setBookFacadeLocal(BookFacadeLocal bookFacade){
        this.bookFacade = bookFacade; 
    }
    
    @RequestMapping(method = RequestMethod.GET)
    public void setUpForm(){}
    
    @RequestMapping(value = "/SpringBookLibrarySystem/loanbooks.htm", method = RequestMethod.GET)
    public String loanBooks(Model model){
        List bookList = bookFacade.notOnLoan(); 
        model.addAttribute("bookList", bookList); 
        return "loanbooks";
        
    }
}

This solved the problem and allowed my to display the results quite happily.
