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:
package accounts.web;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.ServletRequestBindingException;
import org.springframework.web.bind.ServletRequestUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import accounts.Account;
import accounts.AccountManager;

/**
* A Spring MVC @Controller controller handling requests for both the
* account summary and the account details pages. The accountDetails()
* method return an account, corresponding to a given entity id. The
* accountSummary() method returns a list with all accounts.
*/
@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.

Accounts-servlet-config.xml : do you mean accounts-servlet-config.xml ? The "A" must be lowercase.

Please UseCodeTags when posting code or configuration. Unformatted code and configuration is very difficult to read. You can edit your post to include them by using the button.

Do you have accountSummary.jsp under WEB-INF/views ?
