Thread: Spring Mvc 404 error

Hi:

I took a course on Spring 2.56 from Interface21 and the labs I got get it to work during the training.

But when I tried it at home it doesn't work.
I go to the following url and it's find.
http://localhost:8080/accounts/

It display "This is my JSP page. " This is from the default index.jsp page.
When I tried the url as suggested in the lab "http://localhost:8080/accounts/accountSummary.htm"

It gives me a 404 error.

Note, the Tomcat 6 console didnot show any errors meaning it didn't invoke the code for the url.
I am using Myeclipse 8 on Tomcat6.
Here is my Spring information:

Here is the AccountControler.java:

import accounts.Account;
import accounts.AccountManager;
 
/**

 * account summary and the account details pages. The accountDetails()

 */
@Controller
public class AccountController {
 
    private AccountManager accountManager;
 
    /**
     * Creates a new AccountController with a given account manager.
     */
    @Autowired public AccountController(AccountManager accountManager) {
        this.accountManager = accountManager;
    }
 
 
    /**
     * The @RequestMapping annotation takes care of setting the URL
     * this controller will react this.
     */
    @RequestMapping("/accountDetails.htm")
    public ModelAndView accountDetails(HttpServletRequest request) 
    throws ServletRequestBindingException {
        long id = ServletRequestUtils.getRequiredLongParameter(request, "entityId");
        ModelAndView mav = new ModelAndView("accountDetails");
        mav.addObject("account", accountManager.getAccount(id));
        return mav;
    }
 
    @RequestMapping("/accountSummary.htm")
    public ModelAndView accountSummary() {
        List<Account> accounts = accountManager.getAllAccounts();
        ModelAndView mav = new ModelAndView();
        mav.setViewName("accountSummary");
        mav.addObject("accounts", accounts);
        return mav;
    }
}

The database is hsqldb.

Any help or hint would be greatly appreciated it.

Yours,

Frustrated.

What happens if you try this url then?

http://localhost:8080/accounts/accou...untSummary.htm

// Json

Hi:

Thank for the reply.
I figure out what the problem is.
I have to try http://localhost:8080/account/account/Summary.htm

because context is account and the web project is account.

Thank you for your help!!!!
